How It Works
Two ways to seal and deliver your message. Pick the one that fits.
🔒 Time Capsule
Deliver on a fixed date, no matter what.
Create a Time Capsule
Give it a name, write your message, and choose a delivery method — email, webhook, social media, and more.
Set an unlock date
Pick any future date and time. Your capsule is sealed and waiting — no check-ins required.
It delivers automatically
When the date arrives, EternalRelays fires your delivery exactly as configured. No action needed on your part.
⏰ Safety Vault
Deliver only if you stop checking in — your ongoing proof of life.
Create a Safety Vault capsule
Configure a check-in interval — daily, weekly, or any custom period. Set up your delivery method and message.
Keep it alive with regular check-ins
Log in and click Keep Alive, use the API, send an email — whatever fits your workflow. As long as you check in, nothing happens.
It fires if you go silent
Miss your check-in window and the capsule delivers. A grace period gives you extra time — you can also get warning emails before the deadline.
