Verifying your recipients’ email addresses allows you to optimise your transactional email sends, ensure a high level of email deliverability and maintain a strong sender reputation with low bounce rates.

In addition, you may save yourself some money. After all, why use up the sending quota of your MailerSend plan by sending transactional emails to fake, misspelled, inactive or disposable email addresses when you can simply clean your email list?

Thanks to MailerSend’s bulk email verification tool, you can upload your entire recipient list as a CSV file. Afterwards, you can then simply download the email validation results and add invalid email addresses to your suppression list. By the way, they also offer an API endpoint for email verification.


The email verification tool is available for all premium MailerSend plans. Depending on how many emails you send per month, you get a certain number of free credits. One credit is equal to one email address. Additional credits are available as needed in the Add-ons section starting at $10 for verifying 1,000 email addresses.
