How it works: Once you’ve signed up using the chatbot found on the Post Mortem Post Facebook page, you’ll be given the option to select a charity, draft a final post and grant an appointed loved one access to your Facebook account, providing them with everything they need to fulfill your wishes. Upon your death, your legacy contact would simply need to retrieve the shared last post from their inbox and visit the Post Mortem Post Facebook page to learn how to memorialize an account and pin the Post Mortem Post to your timeline.
