Verifying Email Addresses
LeadIQ performs qualification tests for all of the email addresses that it finds.
- We contact their mail server and ask, for example, "Does email@example.com exist?" and their mail server should say yes since that is valid.
- Then we ask "Does firstname.lastname@example.org exist?" and they should say No because it's not valid. If it says No, we know it only accepted the legit email and we consider it verified.
- If they say yes to all formats, we can not verify the email because it's using a Catch-All system and accepting all mail and then rejecting it on the backend. This is an Unverified status.
- We infer the email format based on verified emails from other people at the same company, and mark those as “Best Guess”.
We also do use other methods, including third-party vendors, as data sources beyond our own testing.
