Filter contacts with "There was an issue sending an email to this contact"

Hi,

When making lists of contacts I want to be able to exlude contacts where I get the message “There was an issue sending an email to this contact.”

I don’t want to turn them into a marketing contact. How can I filter them out of a list when they don’t have any of: email invalid, bounced etc?

Hi @EVatsev,

There is no definitive filter for this error message, but you can get very close to finding all of these contacts with the below filters:

  • Unsubscribed from all email is True
    OR
  • Email hard bounce reason is known
    OR
  • Invalid email address is True
    OR
  • Email is unknown

Bonus tip: Create a list of disposable email addresses and one for competitors and also set those to non-marketing.

Best regards!
