You have read an email but need to deal with it on Friday. Leaving it in the inbox may bury it among new messages. Gmail’s Snooze temporarily removes a received message from the inbox and returns it at your chosen time. It does not write or schedule a reply.
Choose a useful return time
In Gmail on a computer, point to the message and choose Snooze, then select the later date and time. Check the actual date instead of accepting a familiar-looking suggestion. For a fictional workshop email, pick a time when you can act on it, not the minute the workshop begins.
Start with one unimportant message rather than a large selection. Keep its subject in a note until you understand the result. If several accounts are open, confirm which mailbox you are changing.
Find the message before it returns
Open Snoozed in Gmail or search in:snoozed. This is the useful check immediately after postponing: you should still be able to open the received message and read its contents. An empty inbox is not evidence that the message was deleted.
At the selected time, check the inbox itself. On mobile, a reminder also depends on notification settings; inbox return and a visible phone alert are different observations. Do not rely on an untested phone alert as the only reminder for a deadline.
Keep sending and receiving separate
Use scheduled sending when you want an outgoing message to leave later. Use Snooze when you want an existing message brought back to your attention. Before postponing an important request, decide whether the sender needs a reply now. Moving the message out of view does not answer the request or complete the work.
