What is email verification and validation?

Email validation checks if your contact’s email address follows a valid format (i.e., is syntactically correct). In other words, it ensures that the address you’re sending to has a valid username and email domain.

Email verification tools then verify that an email address exists and is in use by a real person. Though your email list may contain valid email addresses, it doesn’t mean that they actually exist on those domains. You need to verify them to ensure someone’s on the receiving end.

What is email verification and validation?

How email verification tools get results

Email verification and validation take the guesswork out of email marketing.

For regular email list cleaning, you just need to upload your subscriber list, and the email verifier handles the rest.

Email marketers like you can identify which of your subscribers are real and which are fake (or no longer active). Send your next campaign to these clean email lists and watch your bounce rates hit zero.

FAQs

You can clean up your email list by using email verification tools. You can do this by downloading your list of email addresses and uploading it to an email verifier. Alternatively, if the platform supports it, you can integrate your ESP or CRM directly into the email verification tool via an API connection. Then, the email validation tool will determine which email addresses are valid, invalid, or high-risk. Maintaining an email list with valid contacts will help you maintain proper hygiene.
