The fix? Email verification tools that do the hard work for you.

We’ve rounded up fifteen of the very best email verification tools on the market for you today. Their pros, cons, pricing, and other considerations to help you choose the most accurate, fastest, and easiest-to-use tool in the market.

What is an email verification tool?

An email verification tool checks if an email address is real and safe to send messages to. It spots emails that could hurt your sender reputation, such as:

• Outdated emails that no longer exist
• Addresses with typos
• Catch-all addresses
• Spam traps
• Duplicate emails that already exist in your email lists

In short, it tells you if it’s worth hitting that “send” button.

Best email verification tools in 2025: 15 picks

On the surface, all validation tools offer similar features and pricing. But the devil is in the details, which is why we did some deep research to find out:

• their features,
• how fast each tool works,
• what it costs,
• and what real users say about each tool.

We grouped the tools in different categories to help you make the best choice for your unique use case.

Best professional email checkers for small businesses

Small businesses need affordable pricing, a great core feature set and the ability to scale up or down based on the situation. These are some of our top picks.

#2 ZeroBounce

ZeroBounce is an email verification tool with a seemingly low price point, which makes it attractive to small businesses and those that only need a casual email list cleanup.

It removes invalid, outdated, or fake emails, so you don’t waste time or damage your sender reputation. 

Features:

• Email validation – ZeroBounce claims 99% accuracy.
• Catch-all and disposable detection – spots throwaway addresses, and the average rate for catch-all results was 10.8% in 2024.
• Spam trap detection – helps filter out risky addresses that might get you flagged in the future.
• Email bounce validator – detects emails that will bounce to keep bounce rates low.
• Abuse email detection – flags users who often mark emails as spam.
• Spam trap detection – identifies and removes hidden spam traps.
• Disposable email check – filters out temporary, self-destructing emails.
• Catch-all email check – spots catch-all domains for further scoring.
• Toxic domain verifier – detects harmful, spammy domains.
• Gender identification – adds gender info based on names in your list.
• Free email verifier – checks free, disposable, or toxic emails on demand.
• MX record detection – confirms if an email domain has valid mail servers.

Speed

Speed is where ZeroBounce loses a few points. Verifying 10,000 emails takes about 43 minutes, which is a long wait if you’re on a tight campaign schedule. 

With large lists, delays can turn into missed chances or worse, emails sent to potentially troublesome addresses. So while it gets the job done, it’s not very fast.

Pricing

ZeroBounce offers two main pricing options: pay-as-you-go and subscription plans. 

The cheapest package starts at $20 for 2,000 emails (that’s $0.01 per email verification). If you go for the monthly plan, it begins at $18 for the same amount.

Subscription plans start from $0 for Freemium and go to $249 for Pro.

User reviews

Plenty of people like ZeroBounce. Users mention helpful support, clean results, and fair pricing. Users say the dashboard is smooth and the download options are easy to handle.

But not everyone is excited about using ZeroBounce. ZeroBounce’s features can be overkill for small companies that don’t need deep-level email data. Some users feel it’s too complex for basic use cases. Others pointed out that the interface looks dated and could use a refresh.

#3 EmailListVerify (Email List Verify)

EmailListVerify helps clean up your email lists with all the core features of most validation tools. Their sales pitch is extreme verification speed at a low cost, with a high regard for your privacy.

Features

• Domain & SMTP validation – checks if an email’s domain and server actually work.
• Spam trap checker – spots addresses that could damage your sender reputation.
• Disposable email cleaner – removes throwaway emails that won’t lead to real engagement.
• Catch-all domain checker – helps figure out if you have generic inboxes like info@ in your lists.
• Syntax error validator – flags emails with invalid syntax, like common mistakes and typos.
• Hard bounce checker – filters out addresses that always bounce.
• MTA validator – confirms that mail servers are active and ready.
• Duplicate remover – deletes repeated emails to avoid double trouble.

Speed

EmailListVerify claims it can process over 100,000 emails per hour. But when tested, it needed about 75 minutes to check 10,000 emails. 

This isn’t all that bad, but it’s not the fastest either, and it’s definitely not according to their promises. For big batches, it can still save hours compared to doing things by hand, though speed depends a lot on your list size.

Pricing

You can pay as you go or choose a monthly plan. 

The pay-as-you-go option starts at around $5 for 1,000 emails and ends at $3,620 for 10 million emails. This sounds like a good deal, but it can be a big bite for smaller businesses.

The monthly plans look more affordable, from $16 for 5,000 credits per month. But still leave some questions, like what exactly you get and if there’s a free trial. Some extra clarity wouldn’t hurt.

User reviews

People love the support. It’s fast, friendly, and works around the clock. The tool is also known for effectively spotting spam traps and fake emails.

But not everyone’s thrilled. EmailListVerify works well for simple tasks, but performance isn’t always consistent. Some users report slow processing speeds and occasional issues. And costs may rise faster than expected. It does the job, but when it comes to speed and clarity, it leaves room for improvement.

#4 MailerCheck

MailerCheck is an email verification tool that checks your email list, points out problem addresses, and tells you if your messages are likely to land in inboxes or vanish into spam folders. 

You can verify emails one by one, in bulk, or in real time with their API.

Features

• Email list verification – verify your email list in 3 simple steps.
• Email insights – test your content to improve deliverability and open rates.
• Inbox placement – see if your emails will reach the inbox or go to spam.
• Real-time API verification – instantly verify emails as you collect them.
• Usage reports – track and improve how you collect and manage emails.
• DMARC monitoring and reporting – monitor domain activity to protect your reputation.
• Blocklist monitoring – get real-time alerts if your IP or domain is blocklisted.

Speed

Users say MailerCheck can verify lists within minutes, although we couldn’t find specific information about the actual timeframe. It’s a strong point for users who don’t want to pause a campaign for hours. Real-time checks also happen instantly as users type, so your list stays clean from the start.

Pricing

Pricing is simple: $10 for 1,000 emails in the Email Verification module. Which is quite a lot.

You can go pay-as-you-go or grab a monthly plan for the Deliverability Testing module. There, prices start from $0 in the Free plan and go as high as $975 for the Enterprise plan. Every new account comes with 200 free credits.  Inbox placement and email insights cost 200 credits per run, so you’ll want to use them wisely.

User reviews

MailerCheck gets good feedback for its clean interface, quick setup, and fast results. Users love how well it works with MailerLite and how easy it is for beginners to figure out.

But it’s not all perfect. MailerCheck covers the essentials, but some users feel it lacks depth for the price. It offers fewer verification categories than competitors, which can make results harder to interpret. Plus, it may flag too many valid emails as undeliverable, limiting how much of your list you can safely use.

Best email verification software for agencies and freelancers

Agencies and freelancers have varying needs for verification. Sometimes, you’ll need to verify 200 emails per month and other times, a client may need to verify 20,000 in a single day. They’ll need highly flexible verification tools that are fast, accurate and easy to use.

#5 Emailable

If you’re an agency or freelancer juggling email lists, Emailable is one of the best choices in the market.

Besides accurate email verification, it has inbox warmup and client management tools, making it suitable for agencies or freelancers working for their clients.

Features

• Reliable email validation – verifies syntax, domain, MX records, and server response with anti-greylisting tech.
• Risk detection – flags disposable, role-based, accept-all, no-reply, and full inbox addresses.
• Email quality scoring – assigns a score from 0 to 100 to help prioritize high-quality contacts.
• Data enrichment – adds SMTP provider, names, gender, and corrects misspelled domains.
• Scalable integrations – connects with 50+ tools and supports custom exports, team access, and unlimited API keys.

Speed

Most users say the email verification process is quick, even when checking large lists. You can upload thousands of contacts and get results quite fast. To be specific, verification of 10,000 emails takes 50 minutes. Which is not that bad.

Pricing

You get 250 free credits, and credits never expire, which sounds good. The pay-as-you-go plan starts at $38 for 5,000 emails. Monthly subscriptions are cheaper per email.

There is also a separate Deliverability plan, starting at $149 per month. While Emailable says its pricing is affordable, not everyone agrees, especially if you’re working with a tight budget or a smaller list.

User reviews

The reviews are mostly positive. People love the bulk email verification, API speed, and integration with Mailchimp. Freelancers and small businesses say it saves them time and helps avoid invalid addresses.

Emailable does the job well, but it has a few drawbacks. Verified data is only kept for a month, which isn’t ideal if you want to manage lists over time. There’s also no built-in way to consolidate and organize cleaned emails within the platform – you’ll need to export and handle that separately. For users in regions like Poland, the pricing might feel a bit steep.

#6 NeverBounce

If you’re sending emails for clients and can’t afford bounce-back drama, NeverBounce might save you. It’s built for agencies, freelancers, and growing teams that need to clean large lists without second-guessing the results.

Trusted by brands like Uber and Dell, NeverBounce is also made for serious senders, but it’s easy enough to use without an IT team.

Features

• Clean – bulk email list cleaning to remove invalid and risky addresses.
• Verify – real-time email verification to check addresses as they’re collected.
• Sync – automated list cleaning to keep your email databases continuously updated.
• API integration – plug NeverBounce into your system and verify emails automatically in the background.

Speed

NeverBounce can verify 10,000 emails in about 200 minutes. It’s not lightning-fast, but it’s steady enough for most agencies and freelancers. If your email list isn’t massive, you’ll likely get your results in under an hour. 

However, during busy times or when uploading large batches, a few users mentioned waiting and needing to refresh the page.

Pricing

NeverBounce skips subscriptions and sticks with pay-as-you-go pricing. You’ll pay around $50 for 10,000 emails, but the more you upload, the cheaper it gets, down to $0.002 per email for 4 million credits.

There’s also monthly invoicing, in the Sync plan, if you need it. It’s flexible, but it may be more expensive than other email marketing tools, especially if you clean lists often.

User reviews

Reviews are a mixed bag. On one hand, people love the UI, easy setup, and bulk email verification tools that save time. It works well with email marketing platforms like HubSpot, and users praise its real-time checks.

However, NeverBounce has drawn criticism for inconsistent accuracy, with some users reporting higher-than-expected bounce rates. That can be frustrating when deliverability is on the line. On top of that, customer support is often described as slow or unhelpful, making it harder to resolve issues quickly.

#7 DeBounce

While it’s primarily built for marketers and sales teams, DeBounce works well for agencies and freelancers that need to handle a variety of clients and verification needs.

With lead enrichment features, APIs, and numerous integrations, it can fit into any workflow and improve not just your accuracy, but your sales processes as well.

Features

• Email list validation – kicks out addresses that don’t exist or can’t receive emails.
• Email list monitoring – keep your lists up to date with ongoing monitoring.
• Catch-all validator – identify domains that accept all emails but may still bounce.
• Email validation API – integrate email checks into your own app or workflow.
• Real-time validation widget – instantly validate emails on your website or form.
• Data enrichment – add extra details like name, company, or location to emails.
• Lead finder – discover new leads using targeted email search tools.

Speed

DeBounce can take up to 950 minutes to check 10,000 emails. That’s a long coffee break. It works, eventually. If you’ve got a deadline or a big campaign to launch, the lag might leave you hanging. 

For smaller batches, though, you’ll likely see results sooner. The real-time API runs fast enough for day-to-day lead capture.

Pricing

DeBounce starts at $10 for 5,000 emails, just $0.002 per verification. You can verify up to 5 million addresses, and the more you purchase, the lower the cost per email.

Credits never expire, a rare feature in email marketing tools. It’s one of the cheapest email verification software options around, but that low price may cost you in other areas, like accuracy or speed.

User reviews

Reviews show some users are thrilled with the value for money. They say DeBounce is easy to use, the UI is clean, and results are reliable, most of the time. Others say it’s not perfect.

DeBounce is well-liked for its bulk processing capabilities, but it’s not without flaws. Users have pointed out that customer support can be slow or unresponsive, which makes solving issues frustrating. Another downside is that cleaned email data isn’t stored for long, forcing users to download results quickly or risk losing access.

Best for enterprises and SaaS platforms

The bigger the company, the more comprehensive its needs for clean emails. Large businesses often send out hundreds of thousands of emails at once, and a 1% error can lead to major consequences in bounce rates and sender reputations. The tools below handle large volumes of verifications well.

#8 Kickbox

If you’re running a SaaS platform or scaling email campaigns at an enterprise level, Kickbox is one of the best choices in the market.

Besides high accuracy, Kickbox pride themselves on their ethical cleaning practices, since they don’t clean purchased or scraped email lists.

Features

• Email list verification – clean and validate your entire email list for better deliverability.
• Email verification API – add real-time email validation to your apps or signup forms.
• Deliverability consulting – get expert help to improve inbox placement and sender reputation.
• Free tools – includes an email verifier, spam checker, and disposable email checker for quick, on-the-go checks.
• Sendex™ scoring system – ranks the quality of each email address so you know what’s worth keeping.

Speed

Kickbox handles large lists without choking and returns results rather quickly. Users mention getting the job done in “minutes”. While the exact time is unknown, users seem to be satisfied.

Pricing

You get 100 free verifications to test things out, no credit card needed. After that, pricing starts at $5 for 500 verifications and scales based on the number of emails you want to check.

The more you verify, the lower your cost per email. For example, 2,500 verifications cost $25, while 5,000 verifications cost not $50 but $40.

Plans range up to $4,000 per month, which can be beneficial for large enterprises that manage millions of contacts. It’s flexible enough for growth, but some say it lands on the pricey side if you run checks often.

User reviews

Kickbox gets points for being fast, accurate, and easy to use. The interface is a favorite: simple enough for beginners, sharp enough for teams that live in the dashboard.

Kickbox is easy to use and covers the basics well, but it falls short for users who need more advanced verification. It lacks deeper insights, data enrichment, or detailed categorization of email statuses. For teams looking beyond surface-level checks, the feature set may feel too limited.

#9 BriteVerify

For SaaS platforms and enterprise teams sending emails at scale, BriteVerify steps in. It’s built for those who need to verify large volumes of email addresses across platforms like CRMs, ESPs, or even spreadsheets.

BriteVerify handles basic email checks, while the real power, such as spam trap detection or inbox monitoring, is available only in other BriteVerify tools.

Features

• Real-time validation at point of entry – prevent invalid emails, phone numbers, and addresses from entering your database.
• Bulk email verification – identify outdated, disabled, or non-existent emails across large datasets.
• Multi-channel verification – validate not just emails, but also phone numbers and physical addresses.
• Reputation protection – catch invalid contacts before they hurt deliverability or sender score.
• Web app validation – quickly verify lists in a secure and user-friendly interface.
• High-speed performance – verify emails at scale without slowing down campaigns.
• CRM and tool integrations – validate contacts directly inside platforms like DemandTools and CRMs..

Speed

Based on our findings, BriteVerify can process 10,000 emails within 50 minutes. It manages bulk lists fairly quickly, provided your data is already clean. But if your list is full of duplicates or formatting errors, prep time will slow things down. 

Pricing

You’ll pay $40 for 5,000 emails (that’s $0.008 each). It gets cheaper with volume, but only slightly. For 250,000 verifications, the rate drops to $0.005 each, giving you $1,250. If you’re working with huge lists, the price can climb fast, especially compared to other email verification service providers.

They also have subscription plans, but you must contact sales for the price. 

User reviews

Most users like the easy integration and bulk processing power. It’s particularly helpful when you already use other Validity products.

BriteVerify offers a wide range of features, but that can be a downside for small teams. Its broader focus on contact validation, beyond email, may feel overwhelming if you’re only looking to clean lists and verify addresses. For users who want a simpler, email-only tool, BriteVerify might feel like more than what’s needed.

#10 EmailMarker

If price is your main concern, EmailMarker is the logical choice as you can verify 1,000 emails for just $3. On top of price, it also offers solid accuracy and speed thanks to its real-time verification API.

Features

• Safe email detection – instantly filters out invalid, risky, or spam-trap emails to protect your campaigns.
• Real-time email verification API – verifies emails during entry using PHP, Python, Node.js, or .NET integrations.
• Accurate syntax and domain validation – detects formatting errors and invalid or inactive domains.
• Spam trap and complaint control – identifies and removes harmful addresses that can damage your sender reputation.
• Email deduplication – cleans up duplicates to improve data quality and reduce sending costs.
• Active mail check – confirms if an email will bounce or reach an active inbox.

Speed

Not bad for the price. In tests, EmailMarker cleaned up 10,000 emails in 150 minutes. That’s about half the time it takes most other tools in this price range. It won’t blow your socks off with speed, but for many businesses, it’s quick enough to keep things moving.

Pricing

EmailMarker starts at just $3 for 1,000 verifications. You’ll pay $21 for 10,000 verifications, or $589 for a million. Credits never expire, so there’s no rush to use them. Compared to other tools, it’s one of the cheapest options around.

User reviews

Users love the low cost, basic features, and no-nonsense pricing. It’s ranked high for affordability and turnaround time, but accuracy is where things get shaky. In audits, EmailMarker scored just 74% for accuracy, far below the top-tier players.

Some reviews also mention weak spam trap detection and limited integrations, specifically with Mailchimp. Still, if you need a budget-friendly cleaner that works quickly, it might be worth a try.

Best all-in-one email tools and email list verifiers

If verification is just one of the items on your shopping list, you’re probably looking at tools with a broader feature set. The entries below combine verification with cold email generation, inbox warmup, list management, and others. These tools are ideal for organizations that want to get the most value for their money.

#11 Woodpecker

Woodpecker is a cold email tool loved by agencies, startups, and enterprises because of its variety of features. 

It’s primarily a cold email tool with email verification, but it adds much more value: email inbox warmup, list segmentation, A/B tests, detailed analytics, sequences with triggers and tons of other features.

Features

• Free email verification – remove invalid contacts before sending outreach.
• Free warm-up – prepare your email domain for better deliverability.
• Inbox rotation – send campaigns from multiple inboxes to spread volume and reduce risk.
• Adaptive sending – automatically adjusts sending behavior to stay under spam thresholds.
• Centralized inbox – manage replies from all connected accounts in one place.
• Domain audit – check the health and configuration of your sending domain.
• Condition-based campaigns – trigger follow-ups based on recipient behavior.

Speed

Woodpecker runs checks in real-time: no manual uploads, no delays. Hit “Send,” and the system verifies your emails instantly with Bouncer before they leave your outbox. 

Pricing

Woodpecker starts at $0 with 600 emails and 50 contacted prospects, for 7 days, as a trial. Need more? The Starter plan kicks off at $29/month for 6,000 emails and 500 prospects. Larger teams can scale up to the Growth, Scale, or MAX tiers, with MAX offering unlimited everything at $9,999/month.

User reviews

Users enjoy how Woodpecker “just works.” The built-in verification, free warm-ups, and smart campaigns get special praise, along with the team’s support. Many say it saves time and delivers real results, especially when paired with tools like LinkedIn and CRMs.

However, some users said the Lead Finder needs some improvements. And others note their UI can be polished as well. However, for cold email, Woodpecker has a great all-around package.

#12 Hunter

Hunter.io has become the industry leader for finding email addresses. It has a large feature set, but it’s best known for its powerful email finder. You can add the main details of your leads, and Hunter fills the gaps, giving you accurate, verified email addresses you can use for outreach.

Features

• Campaigns – send and manage cold email outreach.
• Discover – find B2B leads tailored to your target audience.
• Domain search – get a list of email addresses linked to a specific company.
• Email finder – locate any professional’s email address.
• Email verifier – check if an email address is valid and safe to use.
• Signals – identify prospects based on real-time intent data.
• TechLookup – find websites based on the technologies they use..

Speed

Hunter’s speed depends on what you’re doing. Single checks and small bulk tasks are done quickly and are great for quick turnarounds. You get results in seconds, with no long loading bars. For bigger lists, the bulk tool works in the background while you move on to the next task.

Pricing

Hunter has a free plan if you’re just testing the waters: 50 credits per month. Paid plans start at $34 per month and range up to $209 per month (or more with enterprise options). Higher plans give you more searches, verifications, and campaign power.

User reviews

Users like how quick and easy Hunter is. Reviews often mention how fast it finds contacts and verifies them. Two clicks, and done. It’s especially popular with users doing email outreach and lead prospecting.

Hunter has powerful outreach and lead-finding tools, but it falls short in email verification. It lacks some of the deeper options offered by specialized tools. Users have also raised concerns about the email finder’s performance. And since a recent update, some have noticed a drop in available data, which limits its usefulness for prospecting.

#13 Mailgun

The next on our list is Mailgun. It’s an email delivery service that helps businesses and developers send, receive, and track emails. To be specific, it offers features for sending, tracking, testing, and optimizing emails, making it a comprehensive solution for email communication.

Features

• Send emails – seamless email sending with strong reliability, compliance, and speed.
• Optimize emails – improve engagement and ROI by avoiding spam folders and boosting performance.
• Validate emails – use high-speed email validation to reduce bounces and increase conversions.
• Inspect emails – preview emails for accessibility and compliance before sending..

Speed

Mailgun’s email checks happen in real time – no uploading files, no long waits. And according to their website, there is “guaranteed 99% attempted delivery of up to 15 million messages within the first five minutes of sending”. If it’s true, it’s impressive.

Pricing

Mailgun’s free plan gives you 100 emails/day. Paid plans start at $15/month and go up depending on how many features you want. You can even pay $90 per month for 100,000 emails, which is relatively cheap.

User reviews

Mailgun stands out in many key areas, like its ease of setup, especially for developers. Users appreciate how simple it is to monitor IP reputation and track campaign performance through clear reporting tools.

Yet, there are many negative reviews. Many users report serious issues with customer support and account handling. Several reviewers describe being unfairly blocked or charged despite providing full business verification. There’s also frustration over the lack of transparency, inability to escalate support issues, and a strong sense that legitimate businesses are being treated as spam risks without proper investigation

Best email validation free tools & pay-as-you-go options

If you’re not sure you even need to verify your lists, it’s best to test the waters with a free tool. By going through a small sample of your email list, you’ll hopefully see how badly your lists need a thorough clean.

#14 Mailfloss

Mailfloss is proud of their automatic daily cleanup, which is excellent if you constantly add new addresses and don’t want to manually validate emails on a regular basis. They also have a unique typo fixer feature, which automatically fixes things such as “gmial” to “gmail” on the go.

Features

• Easy integration with 40+ email providers – connect tools like Mailchimp, HubSpot, and ActiveCampaign in under a minute – no developers needed.
• Automatic daily cleaning (Autofloss) – keeps your list fresh by removing invalid emails every day without manual effort.
• Decay protection – detects and removes stale or abandoned email addresses each month.
• Smart automation settings – auto-fix common typos, auto-remove or unsubscribe bad emails, and auto-tag or update custom fields for better segmentation.
• Custom cleaning preferences – set cleaning frequency, choose aggressiveness, and decide how invalid emails are handled.
• Manual review mode – option to review flagged emails before taking action like deleting or unsubscribing.
• Detailed reports and analytics – get CSV exports, see status breakdowns, and track results with filtering and sorting.

Speed

Mailfloss users can clean up 10,000 contacts in less than 5 minutes. Really good result.

Pricing

You can start with a free 7-day trial if your email service provider is supported. After that, plans start at $29/month for 10,000 prepaid credits – perfect for small lists or one-time cleanups. The best part? Prepaid credits never expire, so you don’t lose money if you skip a month.

User reviews

There’s only one review for Mailfloss on G2, but it highlights a few key points.

The user praised its broad integrations, affordability, and usefulness for cleaning email lists with bounce detection and duplicate removal.

However, they also noted the lack of 24/7 customer support and the absence of a money-back guarantee, which could be a drawback for first-time users.

#15 Verifalia

Verifalia uses AI to perform over 30 different validation checks for every email address, resulting in really good accuracy. They’re also known for their support for international addresses, making it a solid choice for anyone doing business in the global market.

Features

• AI-powered email list cleaning – removes invalid, risky, or mistyped addresses.
• Detailed results – classifies emails with 40+ status codes for clear reporting.
• Real-time & bulk API – verify emails instantly or in batches with SDKs for major languages.
• Email capture widget – a lightweight, no-code widget for real-time validation on forms.
• Team & reseller support – multi-user access, permissions, and security settings.
• 6,000+ integrations – works with tools like Google Sheets, CRMs, and via Zapier.

Speed

Verifalia is pretty fast. But only if you’re paying for it. On a standard plan, 10,000 emails take about 50 minutes to check. Higher tiers like “Extreme Quality” are slower but more thorough, so you trade speed for detail.

Pricing

You can use pay-as-you-go rates or subscription plans. In pay-as-you-go, you will pay $7.90 for 1,000 credits. And costs can rise to $4,890 for 10 million verifications.

Subscription plans go from $0 for 25 credits, to $9 for 250 credits and $499 for 25,000 credits. Credits don’t expire. It’s easy to underestimate how fast your credits get eaten up, especially if you switch to higher-quality checks.

User reviews

Most users are happy with the results. Verifalia is reliable, accurate, and handles big lists well. The real-time API and bulk cleaning both get praise.

On the downside, there aren’t many user reviews about Verifalia on G2. Thus, you can’t check how the tool is performing in real life.
