wow.com MX records
wow.com publishes a single MX host, mx-aol.mail.gm0.yahoodns.net. With no backup host, a sender that can't reach it queues the message and retries until the server answers or the queue gives up.
51 other domains we checked on the same day also hand their mail to Yahoo Mail servers, with different records from wow.com: ameritech.net, aol.at, aol.be, aol.ch, aol.com.au, aol.com.br, aol.com.mx, aol.de and 43 more.
wow.com SPF record
The record on 5 November 2026 was v=spf1 include:aol.com ?all.
In plain terms, it delegates to aol.com. The top level uses 1 DNS-querying term; SPF allows 10 in total including nested includes (RFC 7208 §4.6.4).
It ends in a neutral ending (?all): the record makes no claim about unlisted servers.
wow.com DMARC policy
_dmarc.wow.com returned no DMARC record on 5 November 2026. Receivers therefore get no instruction about mail that fails SPF and DKIM, which makes @wow.com easier to spoof (RFC 7489).

Can you verify @wow.com addresses?
Our checker treats @wow.com like any domain: syntax, MX, disposable and role checks first, then a made-up address to rule out a catch-all, then your address at RCPT TO, disconnecting without sending. We have not tested @wow.com itself, but its mail goes to the same servers as aol.com, so expect @wow.com results to follow the pattern described there. Each result carries its own reason.
Cleaning a list with these addresses
DNS tells you where mail goes, not whether one person's mailbox still exists. For a list, run the whole file through a verifier before you send: invalid rows come out, risky rows (catch-all, unknown, refused) go in their own segment, and valid rows are safe to mail.
What Yahoo Mail documents for senders
- Yahoo asks every sender to authenticate with SPF and DKIM, and bulk senders to publish DMARC, offer one-click unsubscribe and keep spam complaints low. Yahoo Sender Hub: best practices
- Yahoo publishes the meaning of its own SMTP replies, including the deferrals it uses to slow unfamiliar senders. Yahoo Sender Hub: SMTP error codes
