How to find and verify the reality of an email address?
To do that you can use email validation services: https://esputnik.com/en/blog/10-best-email-list-validation-services
The most popular are ZeroBounce, Voila Norbert, The Checker and QuickEmailVerification.
Here’s what email validators help you do:
- Check the correctness of the email syntax: for example, you can find domain spelling errors, missing “@”, and delete such addresses.
- Find and replace duplicate emails.
- Detect spam traps and remove them. Spam traps look just like normal email addresses, but if you send an email to such an address, email services will consider email marketing campaigns from your domain as spam.
- Reveal contacts with a big number of spam complaints from them.
- Detect disposable email addresses, i.e., email aliases for users’ real addresses. Nobody reads any emails in such mailboxes.
- Find role-based addresses, i.e. addresses associated with a certain company or position, not a person. Such addresses have high unsubscribe and complaint rates.
- Check mail eXchanger (MX) records in the addresses’ domains. A domain without MX can’t receive emails.
- Check for an SMTP connection with the recipients’ servers that shows if their accounts really exist.
- Detect contact activity/inactivity — whether the subscriber is currently using the given mailbox.
To check your email, you can use an API check https://proofy.io/email-validation-api/. To use such a check you will be enough to subscribe to the service. Such an API checking email will give you a clean list of email addresses
