deliverlensWhat this check does
Enter the email address you want to check. Deliverlens validates its format and looks up the domain’s mail-routing records. It does not send a message or contact the recipient’s mailbox.
How to read your result
The result separates address-format problems from domain-routing problems. A correctly formatted address with working mail servers is a good sign, but it does not prove that the individual mailbox exists or will accept a future message.
What to do next
Correct any formatting or domain-routing problem shown in the report, then run the check again. If you need mailbox-level confirmation, use a provider that explicitly offers that coverage.
Common questions
Does a successful check prove the mailbox exists?
No. It confirms the address format and the domain’s published mail routing. The mailbox itself is not contacted.
Does this check send an email?
No. The checker uses the address format and public DNS records only.
