What this means for your email list

What this means for addresses at this domain

dw.com looks like an organisation's own domain. Those are usually good leads, and also where bounces come from: people change jobs and mailboxes get closed. Checking each address, including whether the server accepts any recipient, avoids damaging your sender reputation.

Sender authentication

dw.com has a strict DMARC policy (reject): mail that fails authentication is refused, which protects its brand from spoofing and means anyone sending as dw.com must have SPF and DKIM set up correctly.
