What this check does

Enter an address only when you are allowed to assess it. Deliverlens uses only the coverage advertised by the connected provider and clearly identifies when a result applies to the domain rather than the individual address.

How to read your result

There is no single public blacklist containing every individual email address. The report must therefore be read with its named source and scope. A result cannot prove mailbox existence, consent, or acceptance by every provider.

What to do next

Follow the guidance for the exact source shown in the report. Also review list permission, complaint handling, suppression, authentication, and sending practices before resuming a campaign.

Common questions

Is a domain result the same as an address-level result?

No. Deliverlens labels the scope so a domain signal is not presented as an individual-mailbox finding.

Does a clear result mean an old mailing list is safe to use?

No. Permission, recipient expectations, and suppression rules still apply.
