How does LeadIQ verify email addresses?

The LeadIQ extension does it's own qualification tests for work emails that it finds.

The way we LeadIQ extension verifies emails is as follows:

  • We contact their mail server and ask, for example, "Does alan@leadiq.com exist?" and their mail server should say yes since that is valid.  
  • Then we ask "Does alan.ellis@leadiq.com 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.
  • If we have a verified email from someone at a company, and other emails are unverified, we assume the company uses the same format for everyone, which isn't always the case (for example, we have 3 Ryans working for us, so they have various versions of emails).  We list those as "Best Guess"

We also do use other methods, including third-party vendors, as data sources beyond our own testing.
