Timing
- A newly eligible unread message becomes due after 10 minutes.
- A conversation has a two-hour email cooldown for that recipient.
- Several pending unread messages in the same conversation can be grouped into one email.
- Messages already included in a successful reminder are not repeatedly emailed without newer eligible unread messages.
Conditions checked before sending
The recipient must have an eligible verified email address and the direct-message email preference enabled. The pending messages must still be unread and visible. Hidden conversations, blocks in either direction, unavailable accounts and messages no longer eligible for notification can suppress delivery. Reading the messages before delivery removes that unread reason to send. A recipient with recent active presence is deferred and checked again. Keeping a dashboard tab open does not guarantee continuous active presence: browsers can suspend background tabs or stop their activity updates. An email arriving after a tab becomes idle is therefore possible.Manage the preference
- Open account settings.
- Select Notifications.
- Find the direct-message email preference and enable or disable it.
- Save and confirm the setting remains selected.
