"Unknown" and "Accept_all" are 2 different status responses.

For Unknown emails, 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 dead domains. Since we are not able to conclusively determine the result, we mark it as unknown. 

  • If your ESP’s bounce threshold is 5% or less: DO NOT MAIL.
  • If your ESP has given you a dedicated IP: MAIL SLOWLY.

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. Typically, they are associated with Business email addresses. Since it’s possible there will be some bounces from the Accept-All category, please consider the following before mailing:

  • If your ESP’s bounce threshold is 5% or less: DO NOT MAIL.
  • If your ESP has given you a dedicated IP: MAIL SLOWLY.
