Dead man’s switch for email: how it works (and how to avoid accidental sends)

What a “dead man’s switch” means in practice

At its core, it’s a system that checks whether you’re still active. If you remain active, nothing happens. If you become inactive for long enough, delivery is triggered.

The safest implementations rely on multiple safeguards: repeated check-ins, a waiting period, and (optionally) third‑party confirmation.

LaterWill’s delivery safeguards (high level)

• Periodic check-ins: We email you a “still here?” check‑in on a schedule (30 days by default).
• Multiple reminders: Missing a single email won’t trigger anything.
• Waiting period: Delivery happens only after a longer period of non‑response.
• Optional trusted contacts: If you add them, they can verify your status before delivery.

A simple timeline example

This is what the default flow can look like:

1. Day 0: you write messages and everything stays private.
2. Day 30: check‑in email.
3. Day 60: second check‑in email.
4. Day 90: final check‑in email.
5. Day 90+: if trusted contacts are added, we ask them to verify your status.
6. After the full waiting period (and verification if enabled): messages are delivered to recipients.

How to reduce accidental delivery risk

Most accidental triggers come from simple things: spam filters, changed email addresses, and “I’ll do it later.”

• Add our sender address to your safe senders list once you sign up.
• Use an inbox you check regularly (or set a reminder in your calendar).
• Consider adding a trusted contact if you want an extra safety step.
• Review your setup a few times per year — especially after big life changes.

What to do next

If you’re ready to set this up, start with one message to one recipient. You can expand later — the goal is to reduce friction and make the habit real.
