Free Domain Expiry Checker When Does a Domain Expire?
An expired sending domain silently kills a live campaign and expired domains get snapped up. Enter a domain to see its registrar, registration date, and expiry date pulled from public RDAP registration data.
How this check works
- 01
The domain is looked up via RDAP (the modern, structured replacement for WHOIS).
- 02
Registrar, created date, and expiry date are extracted from the registration record.
- 03
If the registrar blocks automated lookups, you get the manual check path instead.
How to fix common problems
Expiring within 60 days
Renew now, and turn on auto-renew. Campaign domains lapse more often than primary domains because nobody 'owns' them internally.
RDAP lookup blocked
Some registries rate-limit automated queries. Check expiry in your registrar's dashboard or via a manual WHOIS lookup.
Example
A sending domain registered 2025-03-01 expiring 2026-03-01 with auto-renew off is a campaign outage waiting to happen set a renewal reminder at 90 days out.
FAQ
- What happens if a sending domain expires?
- All mail from it fails, links in sent emails break, and after the grace period anyone can register it including bad actors inheriting your reputation.
- What is RDAP?
- RDAP (Registration Data Access Protocol) is the standardized, machine-readable successor to WHOIS for domain registration data.
- How long should I keep old sending domains?
- Keep them registered while any sent emails still matter links and reply threads live for months. Renewal is cheap; reputation loss is not.
