About email threads
Follow-ups in same threads work only if the follow-up email has the same subject, the same recipients, and is sent from the same email account.
Some flexibility:
-
Adding Re: and Fwd: at the beginning is not considered a different subject.
-
The follow-up still threads even if you add new addresses in cc.
-
The follow-up still threads even if you send from an alias.
The option is not available if:
-
You send personalized attachments in the follow-up.
-
You or the recipient permanently deleted the email thread.
