Just changed computer & noticed that snoozed emails do not pop up on new computer, nor are scheduled emails sent, unless I open the old computer/mailspring on that computer.
Do we know if snoozed emails are supposed to migrate across? Is there a way to migrate them across, or is there a way of backing them up, in case of loss of computer, so that losing access to old computer would not lose access to the snoozed emails?
Snooze dates, Send Later schedules and reminders are stored with your Mailspring ID, not on the computer, so they do migrate. When you sign in to the same Mailspring ID on the new machine and connect the same account (same address and IMAP/SMTP settings), Mailspring pulls down all of the existing snooze/send-later metadata for that account on first sync.
One thing to know: the work of sending a scheduled message or returning a snoozed thread to your inbox is done by whichever computer is running Mailspring at the time. If the new install hasn’t finished its initial sync yet, or the old one is still running and beats it to it, it can look like nothing happened. Give the new machine time to finish syncing, and sign out of or remove Mailspring on the old one so two copies aren’t both trying to do the job.
For backup purposes: because this metadata lives with your Mailspring ID, losing the computer doesn’t lose your snoozed mail. The threads themselves are on your mail server (in the Snoozed folder/label) and the dates come back when you sign in again.
