Sending new messages to subscribers who have already finished the sequence
If you add new messages to a follow-up sequence and want "Finished"
subscribers to get those new messages, here's the process:
1. Set autoresponder status to "Suspended".
2. Add your new messages.
3. Set autoresponder status to "Active".
4. Filter subscriber list by autoresponder and status "Finished"
5. Use Subscribers > Group Tasks > Edit to set their status to "Active" en masse.
They will be added back into the sequence and carry on from where they left off.
After they have received the new messages, they will be re-flagged as "Finished".
Note that the above will only work if messages are added at the end of the sequence,
not in the middle of it.
