In case the same contact has hard bounces in three consecutive campaigns, Benchmark email
automatically flags the contact as a "Confirmed Bounce". A "Confirmed Bounce" contact will be excluded from your active contact count, and will not be sent any email, if the contact list is selected again. In case a previously bounced email is opened in another campaign before it has been flagged as "Confirmed Bounce", the contact's bounce counter is reset to zero. This allows bounced emails, to remain in the active contact count and not be flagged as "Confirmed Bounce". The "Confirmed Bounce" contacts are listed separately in your contact list.
If an email has bounced for a known, permanent reason based on the error codes returned by the recipient’s email server, we remove that contact from your list in the first instance.
Some of the examples of the error codes would be
- 550 No such user (xxx@xxxxxxxxxxxx) Giving up...
- 5.1.1 unknown or illegal alias: xxxx@xxxxx ...
- Recipient address rejected: User unknown
To manually delete bounced address from your Contact List, you can use the ‘Clean List’
option in the Contact List details page.
