Anything written from your own connected mailbox can be booked to send later instead of now: the reply drafted at eleven at night that should land at nine in the morning, the follow up that belongs on Monday. The control sits in the composer, wherever the composer opens from.

- 01
Write the email as usual, then open the send options beside Send and choose Schedule send.
- 02
Pick a Send at date and time, or take one of Tomorrow 9:00 am, Monday 9:00 am and In 1 hour.
- 03Press Schedule. The composer swaps its header for the booked time.
Every time here is read in your organisation's timezone, not your browser's, so a member working from another city books the hour everyone else is expecting. The instant has to be at least a minute away and no more than a year out.
It stays a draft
Nothing about the message is frozen when you schedule it. The draft is still an ordinary draft, still editable, and what is on it when the clock comes round is what goes out. That is worth knowing both ways: a correction typed at 8:55 makes the 9:00 send, and so does a half finished sentence.
The booked draft shows up in Scheduled on the Outgoing tab, carrying three buttons: Edit to reopen it, Send now to go early, and Unschedule to put it back to an ordinary draft. The same three sit in the composer. Group emails can be scheduled too; when the time comes, the group starts sending its individual emails.
It sends once
The send claims the draft before it composes anything, so a retry, a restart or a duplicate trigger cannot post the same email twice.
When the time comes
The send fires on the minute you chose. A sweep runs every five minutes behind it and picks up anything the first attempt missed, so a hiccup in the queue costs a few minutes rather than the email.
Some things cannot be recovered by trying again: a recipient address that is no longer valid, an attachment that has gone, mailbox access that has expired, or a merge field whose contact link was removed after you scheduled. In each of those the schedule is cleared, the draft is left exactly as you wrote it, and you get a Scheduled email could not be sent notification. Fix the draft and send or schedule it again. That notification goes to the mailbox owner and is on by default both in app and by email: see Notifications.
An account that has gone read only is the other case worth naming. Scheduling is refused outright while an account is read only, and a draft scheduled before that happened fails at the other end with the same notification. See Read-only accounts.
