What is it, why should you care and how to get started? You’re about to find out.

What is real time email verification?


Real-time email verification is a process that instantly checks the validity and accuracy of an email address as soon as it’s entered or submitted.

It ensures that the email address is not only correctly formatted but also exists and can receive messages, effectively lowering the bounce rate and keeping bad email addresses at bay.

This helps prevent the use of fake or mistyped email addresses, reduces errors and improves the overall ROI of your email marketing efforts.

In simple terms, it’s like having a quick and automatic way to confirm if an email address is real and ready to use before sending any emails to that address.

How does a real time email verification service work?

Real-time email verification involves a series of steps to keep the accuracy and validity of email addresses. Here is how it goes.

Data input

Users or systems input email addresses into a sign-up form, database, or any platform where email addresses are collected.

API integration

For real-time verification, businesses often integrate an email verification API into their systems. This API acts as a bridge to the verification service.

Bouncer - email verification API

API request

When a user submits an email address, the integrated API sends a request to the email verification service. This request includes the email address that needs validation.

Verification process

The email verification service performs various checks, e.g. syntax validation. This helps with checking whether the email is correctly formatted. It also checks the existence of the email address by interacting with mail servers.

Results returned

The verification service sends back the results of the verification to the API. This typically includes information about whether the email address is valid, invalid, or risky.

Integration with platforms

The API then communicates the results back to the user interface, sign-up form, or the system where the email was originally entered.

Action based on results

Depending on the verification results, businesses can take appropriate actions. For example, they may allow the user to proceed if the email is valid or prompt for a correct email address if it’s invalid.

Improving sender reputation

Keeping a clean and valid email database contributes to a better sender reputation. This is crucial for email deliverability, as mail servers are more likely to accept emails from senders with good reputations.

Your reputation is preserved as you get rid of spam traps, disposable emails, and all other types of risky emails with careful email list cleaning.

Preventing spam folder placement

Validating email addresses helps prevent emails from being flagged as spam. This is because mail servers are more likely to deliver emails to the inbox if they come from verified and reputable sources.

Real-time email verification acts as a proactive measure to maintain a clean email database, enhance sender reputation, and improve overall email deliverability.

Why is real time email verification important?

Real-time email verification should be a topic of your interest for several reasons:

Saves time and money (since you don’t have to verify later)

When you verify email addresses in real-time, you eliminate the need to address verification issues later in your marketing campaigns. This way, the email verifier saves you both time and resources, as you can verify invalid addresses in bulk.

Scenario: picture gearing up for a product launch campaign to your email subscribers. Without real-time verification, you risk sending emails to your entire list, including potentially outdated or invalid email addresses.

Impact: this could result in a large number of bounces, negatively affecting your sender reputation and wasting resources on sending to non-existent addresses.

With real-time verification: thanks to employing real-time verification to verify email addresses as they are collected or used, you make your campaign target only valid recipients. In this way, you save time and resources spent on handling bounce-related issues later. This is especially crucial for efficient bulk email list verification.

No more typos in email submissions (as it takes a look at syntax too)

The verification process includes syntax checks for invalid email addresses. The check verifies whether email submissions are free from typos or formatting errors. Doing this typically leads to more accurate and reliable data.

Scenario: imagine running a sign-up campaign where users manually enter their email addresses. Typos are very likely to occur during manual entries.

Impact: typos in email addresses lead to delivery failures. This can potentially cause your subscribers to miss out on important updates.

With real-time verification: real-time verification, which includes syntax checks during sign-ups, prevents typos from entering your database. This guarantees that your subscribers’ list is accurate from the start. The result? A clean and valid email list. A clean email list means a lower email bounce rate and email content that reaches real people.

No more fake, outdated, and spam emails

Real-time verification identifies and filters out fake, outdated, or potentially spam-related email addresses. The outcome of this is that your communication reaches genuine recipients from your clean email list.

Scenario: think about preparing a targeted promotion for loyal customers without real-time verification. It may result in including fake, outdated, or spam-related addresses.

Impact: sending promotions to these addresses can harm your sender reputation and impact email deliverability, as these are bad emails that may not even exist on an email server.

With real-time verification: real-time verification filters out fake, outdated, and potentially harmful addresses so that your promotions reach genuine and engaged customers. This practice is fundamental for safeguarding your sender reputation and email service provider relationships.

Improved overall email marketing metrics

With a clean and validated email database, your email marketing campaigns are more likely to achieve higher deliverability rates, engagement, and conversion. As a result of this, you can get ready to boost your overall marketing metrics and use your email marketing tools to the best of their capabilities.

Scenario: as an example, take crafting a compelling newsletter and aiming for high engagement from subscribers.

Impact: you get a high number of bounces and low engagement rates because of invalid addresses. This negatively impacts email marketing metrics and campaign success, as well as your email sender reputation.

With real-time Verification: integrating real-time verification contributes to higher deliverability rates, increased engagement, and improved conversion. This approach positively influences overall email marketing performance, especially when doing bulk email verification for large lists. You get to remove all types of risky email addresses, including disposable email addresses.
