Never let a domain expire by accident

Registrar reminders aren't reliable

The email on your registrar account might be an old address. Renewal notices go to spam. The card on file expired. You renewed through a reseller who doesn't forward alerts. Any of these, and you find out the domain is gone when someone else has it.

A lapsed .com can be in someone else's hands within 24 hours. Domain auctions move fast.

How it works

1. 1

   Add your domain

   Enter the domain. Domain Sentinel reads the expiration date directly from the RDAP registry, not from your registrar account.

2. 2

   Set your reminder schedule

   Choose when you want to be notified: 60, 30, 7, and 1 day before expiry. Domain Sentinel sends an email at each interval.

3. 3

   Renew on time

   You get the email, you renew with your registrar, done. Domain Sentinel picks up the updated expiry date automatically.
