Ready to verify your email list?

There are no long term commitments, so you can see the magic for yourself. Try MailerCheck for free and get 200 credits to start. No credit card required.


Speaker: To begin the email verification process, select the email verification tab and click on "Verify New List." You have two options: you can either upload a file with email addresses or integrate MailerCheck with your email marketing software to verify your list directly from there. In this case, I will upload a CSV file with 11 email addresses, which means it will consume 11 credits. To check your credit balance, look under your account's name. If you need additional credits, you can purchase them on the same page. Click "Verify List" to scan the file. Once the verification is complete, a report will be generated, and a copy of the report will be sent to your email. Click "View Details" to access the report.


Speaker: At the top of the report, you will see the "Valid Addresses" section. These are the email addresses that are safe to send content to. The remaining addresses are more likely to bounce, so it's better to remove them. You can select the "Valid Addresses" category, download the emails, and now you have an updated list of valid addresses to work with.


Speaker: Moving on to the "Risky" category, we have separated the email addresses that are likely to bounce for different reasons. A "Catch-all" email refers to an address that may not belong to a real person. A "Mailbox Full" result indicates that the emails will not go through to that inbox because it is likely not being checked at all.


Speaker: "Role-based" emails are those that do not include a person's first name and instead use generic terms like "admin@" or "info@." These email addresses are also considered risky as they cannot be linked to an actual person. We also have emails that have recorded bounces in the past and "Unknown" emails that might be valid, but there isn't enough information to be 100% sure. These emails are placed in the risky section.


Speaker: The "Do Not Send" section includes all the email addresses that are highly prone to bouncing back for various reasons. This can include syntax errors, typos, non-existent mailboxes, temporary inactivity, or being blocked. It is strongly recommended to remove these email addresses from your list to ensure better deliverability. Sending emails to these addresses should be avoided.


Speaker: You can select and download any of these sections (such as "Do Not Send" or "Risky") to review the verification results in more detail. To access the results, go to the email verification page.

By regularly verifying your email list and removing problematic addresses, you can maintain a high-quality email list, improve deliverability, and enhance the success of your email marketing efforts.
