What this check does

Enter the registered domain. Deliverlens requests its RDAP registration data and looks for a registration event.

How to read your result

Age provides registration context. Sender reputation, ownership history and future delivery depend on additional evidence. Missing dates and provider failures remain inconclusive.

What to do next

Review the date alongside authentication, sending history and receiver feedback. Confirm registration details with the registrar if the source omits a date.

Common questions

Can I check a sending subdomain?

Use the registered domain for registration evidence. A sending subdomain can have a different operational history.

Does an older domain guarantee delivery?

Delivery decisions also depend on authentication, reputation, content and recipient expectations.
