Hi!
When enrolling multiple people on a sequence there’s a great number of contacts that are not going to be delivered the email, and I will receive an automated email that most of the times read “Adress not found” - Email Delivery Subsystem; or “Your message couldn’t be delivered” - Postmaster.
I would like to know if there’s a chance for me to identify them over HubSpot and not Gmail, so the sequence stops and I can update the information.
Also, is there a chance this same idea can be drafted over a workflow, so that any time I receive this kind of automated email, the sequence stops and it notifies me?
Thank you 
Hi @ElisaAlvarez,
When a contact bounces in a sequence, they will automatically be unenrolled, see here. When you navigate to your sequence (Menu > Automation > Sequences) and click on it, you should see a list at the bottom of the screen where you can filter sequence activity by status, including “Errors”:
Technically you can re-build sequences in marketing workflows, yes. You’d have to create automated emails for each email of your sequence. Similar to sequences, you’d see bounces in the workflow Performance tab. However, these workflows wouldn’t stop when a contact replies to an email – a key feature of sequences. (see here)
Also keep in mind that automated workflow emails would be sent using your connected email domain. Sequence emails are sent through your connected personal inbox.
Hope this helps!
Thank you,
I understand those bounces and how they reflect themselves as errors, however, the ones that I’m interested to know if I can join on a list or identify, are the ones that cannot be sent to the contact because they have been stopped. When I enroll multiple contacts on a sequences, it’s ver common that I receive emails that look like this:
I’d love to know how to get them together, for they are contacts that cannot be reached and that should be updated.
Hi @ElisaAlvarez,
My apologies for the looong delay here.
You should be able to get this list of contacts by creating an active contact list and filtering for contacts with “Email hard bounce reason is known” and “Now in sequence has ever been equal to true”.
Hope this helps!
