There are a few possible reasons a user could not be receiving emails from the BB CRM sync. Here are some common ones.

1.  There were no new sync errors - the sync email will only be generated if there are new sync errors since the last sync.  If there were no errors, this means that there are no records in the CRM table B2TROWS to process.

2.  The user is not part of the email list that the sync goes to. Team Approach Support can check this in the sync settings (see Internal notes).

3.  The email notification is set up with the wrong SMTP server. Team Approach Support can check this in the sync settings (see Internal notes).
