These messages are dispatched via email, activated when the user is marked as deceased. The procedure encompasses two notification choices: the Friend's Check and the Self Check.

The Friend's Check requires sharing a confidential code with a trusted person who can confirm the user's passing, thus initiating the delivery of the posthumous messages. On the other hand, the Self Check allows users to set periodic check-ins, and if there is no response within the specified time, the messages are automatically sent.

Crafting posthumous messages on GoodByeMemo is a straightforward and intimate process. Users can employ their smartphones to compose messages, include photos, attach files, and even record videos, rendering each message distinct and profoundly meaningful.
