Complaints range from incomplete bulk verification to misclassified valid emails and limited automation.
So, is there a better option?
You’re in the right place if you want higher accuracy, deeper insights, and more control over your email lists.
Let’s check out the best MailerCheck alternatives – and find the perfect tool for you.
What is MailerCheck?
MailerCheck helps businesses with email deliverability by checking email lists, predicting inbox placement, and reviewing email content.
It looks for syntax mistakes, invalid email addresses, and spam triggers to prevent emails from landing in spam folders.
With its email verifier, users can check single addresses, scan full lists, or run real-time verification through an API.
The email insights feature detects problems like:
- Spam-related words,
- Broken links,
- Blocklist issues.
At the same time, inbox placement tests show if an email will reach the inbox or get filtered out before sending.
Businesses use MailerCheck to protect sender reputation, reduce bounces, and avoid wasted costs from sending emails to bad addresses.
The tool also keeps track of domain activity, provides usage reports, and gives marketers data-driven insights for better decision-making.
MailerCheck’s top features
#1 Improve deliverability by cleaning your email list
MailerCheck’s email verifier helps identify and remove bad email addresses. Upload your list, and it quickly checks which contacts are safe to keep.
#2 Get insights beyond basic verification
MailerCheck provides email insights, showing which addresses are unreliable and which might still work. It also gives recommendations for managing your list, helping you decide whether to keep, remove, or organize contacts into different groups.
#3 Check for issues before sending emails
MailerCheck scans your content to highlight these risks. Fixing them before you hit “send” reduces the chances of emails getting lost or ignored.
#4 Know where your email will land
With inbox placement testing, MailerCheck runs your email through different email service providers like Gmail and Outlook. You’ll know if it will arrive in the inbox, land in spam folders, or be blocked completely.
#5 Validate emails in real time
MailerCheck’s email verification API checks addresses as they are entered.
You’ll know instantly if someone signs up for your mailing list with a fake or mistyped email. This helps prevent bad contacts from being added in the first place, keeping your email deliverability high.
#6 Analyze your email list’s performance
MailerCheck doesn’t just identify invalid email addresses—it gives a complete overview of your list’s health.
With usage reports, you can track your emails’ performance across different uploads, integrations, and API activity. Having this data helps with bulk email list verification and long-term list management.
#7 Monitor your domain for unauthorized use
MailerCheck watches for suspicious activity and alerts you to potential problems before they impact your inbox placement.
#8 Find out if you’re on a blocklist
MailerCheck scans major blocklists and notifies you if your domain or IP address is flagged. This allows you to resolve the issue before it affects your email marketing campaigns.
#9 Keep your email list in good shape
MailerCheck includes tools to verify email addresses, check email content, and monitor email deliverability. Keeping your mail addresses clean and valid can reduce bounces and improve how your campaigns perform.
Why MailerCheck isn’t the best
MailerCheck promises to verify email addresses, clean up lists, and improve inbox placement.
But not everyone is happy with it.
Some users say it misses key features, others complain about how it handles bulk email verification, and a few question its email verification process altogether.
Let’s take a closer look at the downsides.
#1 Bulk email verification feels incomplete
For a tool that markets itself as an email verification service, some users feel MailerCheck doesn’t go far enough when handling large lists. Adam B. pointed out that “For the price – it is missing a couple of features that other services have.”
He also mentioned that it lacks detailed email address verification categories, saying, “It has just basic categories for emails that have been checked when it should have a few more like those emails that may bounce but worth a try.”
When dealing with bulk email list verification, knowing which emails are active email addresses and which are risky is important. If a tool isn’t giving clear answers, users are left guessing—and that’s not helpful when running email marketing campaigns.
#2 Invalid email addresses might be misclassified
One of the biggest concerns is how MailerCheck flags invalid email addresses. Adam B. noted, “I also feel like it is invalidating a few more emails than other services.” If an email verification software marks good contacts as bad, businesses could delete valuable leads for no reason.
This also raises questions about the email verification process itself. How reliable is the mail server validation? Are emails being flagged correctly? This uncertainty can be frustrating for businesses that rely on accurate data.
#3 Not enough automation for email marketing campaigns
A good email verification API helps keep lists clean automatically for companies running email marketing campaigns. However, according to Alessandro G., MailerCheck doesn’t do enough: “Too limited option in workflow automation. Need more triggers and actions.”
Without proper domain verification and automated email address validation processes, users have to clean their lists more often manually. That takes time—and in email marketing, time is money.
#4 Lack of transparency about the email verification process
Some users also feel that MailerCheck doesn’t explain how it verifies email addresses compared to other tools.
Cody C. said, “I would say lack of education for the customer. WHY exactly are they different from Bouncify/NeverBounce? If they had a 1-2 min video explaining the backend details/complexity of how they verify emails (different).”
When choosing an email verification software, users want to know how their email address verification is handled. Without clear mail server validation steps, businesses don’t know if they can fully trust the results.
