Why can't I unblock a bounce myself?

If a contact has bounced, it is completely and permanently blocked.

This means that the contact can never be written to again. A final block will be applied if, for example:

  • the email address is wrong - either because there is a typo in the email address, or because the recipient has deleted this email address
  • there is something wrong with the domain (the one behind the @) - again, a typo may be the cause of this.
  • the email has been┬árejected due to suspected spam.
  • the sender domain is rejected because of a bad reputation.

If you were to write to contacts who are already blocked, this would give you a negative reputation. The emails are much more likely to be rejected as spam and no longer arrive in your recipients' inboxes - a situation that should be avoided.
