Snooze or set a reminder
Snoozing hides a message from the ordinary list until the chosen time. You can bring it back early from the snoozed folder. A reminder helps you return to a message without hiding it.
Follow up when there is no reply
Before sending, set a reminder for a conversation that has not received an answer. Review scheduled reminders in settings.
Keep the app running
Postosha must be running, including in the system tray, for timely notifications. Windows notification permissions and Do Not Disturb also affect banners. Snoozing a received message is not scheduled sending.
