How to send messages after death

Can you send a message after you die?

Yes. You can't send anything yourself once you're gone, so every method comes down to the same two parts: you write the message now, and something or someone delivers it later. That something can be a person you trust, a service that waits for a date, or a system that waits for you to stop responding.

What changes between the options is how they decide the moment has come, how private the message stays while it waits, and what happens if the person or service you relied on is no longer around. Those three questions, trigger, privacy and reliability, are the ones worth asking of any approach before you trust it with your last words.

Ways to leave messages for loved ones

Here are the common ways to leave messages for loved ones after death, with the honest strengths and weaknesses of each.

• Scheduled email services

  You write an email and pick a future date. Simple and free, but a date is a guess. Send it too early and a living you has to explain it; too late and it arrives years after it mattered. Most of these services also store your message in plain text, so the company and anyone who breaches it can read it.

• A letter held by a lawyer or executor

  A sealed letter kept with your will is private and widely understood. The downsides are cost, friction when you want to update it, and timing: it is usually only opened once the estate is being dealt with, which can be weeks or months after death. It also relies on the lawyer still practising and the executor knowing it exists.

• Password manager emergency access

  Several password managers let a trusted person request access, which is granted if you don't decline within a waiting period. This is good for passwords and poor for personal messages: it gives one person everything, and it is designed to share credentials, not a letter to your children.

• Social media legacy contacts

  Facebook, Apple and Google let you name someone who can manage or download your account after death. This keeps a memorial page tidy and lets a relative recover photos, but none of them deliver a message you wrote. They also typically need a death certificate before they act.

• A dead man's switch

  You check in on a schedule you set. If you stop and the reminders go unanswered, your messages are released to the people you named. The trigger follows your life rather than a calendar, and a well-built one encrypts the message so the service can't read it. The trade-off is that you have to keep checking in, and recipients need the key you gave them.

Email scheduling vs a dead man's switch

These two get confused because both are apps that send a message later. The difference is what they wait for. A scheduled email waits for a date. A dead man's switch waits for silence. Since nobody knows their date, the switch is the one that can actually answer the question "deliver this only if I'm gone".

There is a second difference that matters for anything personal. A scheduled email is usually an ordinary email, sitting on a server, readable by the company that holds it. With PostMortem, the message is encrypted on your phone before it is uploaded, using a personal access key that you generate and keep yourself. Box names, recipient emails and the check-in schedule are not encrypted, but the message itself is. The recipient decrypts it on the web with the access key card you shared with them in advance.

Scheduling still has its place. If you want a birthday note to land on a fixed date regardless of whether you're alive, a scheduled email is the right tool. If you want a message that only goes out when you can't speak for yourself, you want a switch. Our guide to what a dead man's switch is goes deeper on the mechanism.

What to put in a final message

People freeze at this step because "final message" sounds like it has to be profound. It doesn't. The messages that families say they treasure are usually short, specific and in your own voice. Write the way you talk.

Keep practical and personal content separate where you can. A letter that says "I'm proud of you" shouldn't also carry the router password. In PostMortem each message box can hold up to three text messages, login credentials for accounts, up to five file attachments (images, PDFs, documents and audio, 20 MB each), and financial records such as debts you owe or assets you want known about, so you can keep a warm letter alongside the practical details without mixing them into one wall of text. If you want help with the letter itself, see our guide to writing a legacy letter.

• The personal part

  What they meant to you, something you never got round to saying, a memory you want them to keep. One honest paragraph beats three pages of ceremony.

• The practical part

  Where documents are, who to call, which accounts exist, which subscriptions to cancel. Our digital legacy planning guide has a checklist.

• Access

  The email account that everything else resets through, the phone PIN, the password manager. See passwords after death for what to share and how.

• Wishes

  Funeral preferences, what to do with pets, who gets the guitar. Keep in mind that a message like this is not a will. Whether informal wishes carry any legal weight varies by country and state. This is general information, not legal advice.

How to make sure it actually reaches them

Delivery is where most plans quietly fail. A letter nobody knows about is never opened. A scheduled email goes to an address that was closed years ago. A message encrypted so well that the recipient can't open it is the same as no message at all. Nothing can promise delivery, but you can remove the common points of failure.

First, use an address the recipient will still have. A personal email is better than a work one. Second, decide whether to tell them in advance. PostMortem lets you choose per box: it can send an intro email so the person knows a message exists, or stay silent until release. Telling them is usually the safer choice.

Third, make sure they can open it. With end-to-end encryption, the recipient needs the access key card you shared with them beforehand; without it the message stays locked. Hand it over in person or store it somewhere they will find. Fourth, keep the reminders in mind on the recipient side too. After release, PostMortem emails a recipient who hasn't opened the message every 14 days, up to 12 times, so one missed email isn't the end of the story.

Finally, test it. PostMortem includes a test box: a one-tap sample on an hourly interval addressed to a +postmortem_test alias of your own email, so you can watch a release happen from check-in to decryption before you trust it with anything real.

How PostMortem does it

PostMortem is a free app for iOS and Android built around message boxes. Each box holds what you want delivered and who should receive it, and each has its own check-in interval: daily, weekly, monthly or a custom period of your choosing.

Checking in is one tap in the app, and one check-in resets every active box at once. If you don't check in, reminders arrive by email and push notification at about 60%, 70%, 80% and 90% of the interval, with the last one marked as final. Only when the interval fully runs out is the box released.

At release, each recipient gets an email with a link to their recipient page, and you get an email telling you the box went out. Recipients decrypt the contents in the browser with the access key card you gave them. Messages, passwords, files and debt details are encrypted on your phone before upload (box names, recipient emails and the check-in schedule are not), and because the key is yours, PostMortem can't read those contents or recover them if the key is lost. Account sign-in is by email and a 6-digit code, with optional Face ID or fingerprint, and you can delete your account from the app whenever you like.

Common mistakes when leaving messages after death

• Relying on one person

  If the only copy lives with your brother and he moves house, loses his phone or dies first, the message is gone. Name more than one recipient for anything that matters.

• Guessing a date

  Scheduling to a date you picked at 40 is a coin toss. Prefer a trigger that follows whether you're still responding.

• Writing once and never updating

  People divorce, children grow up, accounts change. Pick a method you can edit in minutes, and reread your messages once a year.

• Hiding the key with the message

  Encryption only helps if the recipient has the key and an attacker doesn't. Share the access key card separately and in advance.

• Treating it as a will

  A message can say what you want; it generally can't enforce it. Rules differ by country and state, so keep legal matters in a proper will. This is general information, not legal advice.

Frequently asked questions

• Can I schedule a message to be sent after I die?

  Not to a date, because nobody knows it. What you can do is use a dead man's switch: the message is held until you stop checking in and the reminders go unanswered, then released to your recipients. That ties delivery to your life rather than a calendar.

• Is there an app that sends messages after death?

  Yes. PostMortem is a free iOS and Android app that works as a digital dead man's switch. You write messages, attach files and credentials, name recipients, and check in on a schedule. If you stop responding, the messages are released.

• What happens if I forget to check in?

  You get reminders by email and push notification at about 60%, 70%, 80% and 90% of your interval, with the last one marked as final. A single tap in the app resets every active box. Only if the full interval runs out with no response is anything sent.

• Can PostMortem read my messages?

  Not the contents. Messages, passwords, files and debt details are encrypted on your phone before upload with a personal access key you generate and save to your photo gallery; box names, recipient emails and the check-in schedule are not. The flip side is that if you lose the key and nobody has the access key card, the contents can't be recovered.

• How does the recipient open the message?

  They receive an email with a link to a recipient page on the web, where they scan or upload the access key card you shared with them in advance. They don't need the app or an account. If they haven't opened it, they get a reminder email every 14 days, up to 12 times.

• Is a message left this way legally binding?

  Generally no. A message can express your wishes, but a will is a separate legal document with its own requirements, and the rules vary by country and state. Use a message to explain and to say goodbye; use a will for anything that needs to be enforced. This is general information, not legal advice.

• What can I include besides text?

  Each message box can hold up to three text messages, login credentials, up to five file attachments of 20 MB each (images, PDFs, documents and audio, but not video), financial records such as debts or assets, and one or more recipients identified by name and email.
