Following are the email verification status values you would notice when you verify the emails using MassMailer Email Verifier.

1. VALID

The email has a valid account associated with it.  SAFE TO  E-MAIL


2. INVALID

The email address is invalid.  DO NOT E-MAIL


3. ACCEPT ALL

Accept-All emails are when a server is set to receive all emails at a specific domain, meaning these domains accept any email you send to them at first.  So it appears as if all of the emails are Valid at that domain, but the company actually has a firewall or another spam tool that may remove the email message or send a bounce message at a later time.  Since it’s possible there will be some bounces from the Accept-All category, please consider the following before mailing:

  • If you are using a Shared IP address then we don't recommend emailing them: E-MAIL AT YOUR RISK
  • If you have opted for a Dedicated IP address from MassMailer:  E-MAIL SLOWLY


4. UNKNOWN

The email address looks good but the associated domain is not responding. This could be a temporary status for domains having intermittent issues or a permanent issue for dying domains. There will be some bounces from the Unknown category so consider the following before mailing:

  • If you are using a Shared IP address then we don't recommend emailing them: E-MAIL AT YOUR RISK
  • If you have opted for a Dedicated IP address from MassMailer: E-MAIL SLOWLY

There are only 4 statuses for an email in MassMailer Email Verifier.


  1. Valid: The email represents a real account / inbox available at the given domain

  2. Invalid: Not a real email
  3. Unknown: For some reason we cannot verify valid or invalid. Most of the time a domain did not respond quickly enough.

  4. Accept All: These are domains that respond to every verification request in the affirmative, and therefore cannot be fully verified.
