Autumn replied on 12 February, so steps 3 and 4 never ran.

The reply landed four days after the first email. Hisendy recorded it, cancelled the rest of the sequence before the scheduler picked the work up, and moved the thread into Conversations.

01Pace

Paced like a person, not a queue.

A new mailbox starts at eight a day and only moves up when the last stage stayed clean. Pick your mailboxes and the working window to see the first fifteen days.

03The path

Five screens from a list to a scheduled campaign.
