Frequently Asked Questions

How does the domain expiry checker work?
We look up your domain's registration data via RDAP (Registration Data Access Protocol) and WHOIS to find the expiry date. This is the same data registrars use.
What happens if my domain expires?
When a domain expires, your website goes offline, emails stop working, and you risk losing the domain permanently. Most registrars offer a grace period (30-45 days) but charge extra for late renewal.
How often are expiry notifications sent?
We send the first notification 7 days before expiry, then daily reminders until the domain is renewed or expires. We also detect renewals automatically and send a confirmation.
Do you support all domain extensions (TLDs)?
Yes, we support all major TLDs including .com, .net, .org, .io, .dev, .me, country-code TLDs, and most new gTLDs. For subdomains, we automatically check the root domain.
Is this really free?
Yes, 100% free with no account required. We just need your email to send notifications. You can unsubscribe anytime with one click.
