Is arnet.com.ar a valid email domain?

Free providerChecked 2026-11-06

arnet.com.ar has no MX record, so mail falls back to the domain's own address record. Most senders still deliver, but it is a fragile setup.

It is a free, public mailbox provider, and it is not on our disposable list.

SPF is published. DMARC is set to reject.

What this means for your email list

Is a free-provider address a problem?

Addresses at arnet.com.ar are legitimate and deliverable in general. What goes wrong is the mailbox part before the @: typos, old accounts and abandoned inboxes. That is what per-address verification catches.

Sender authentication

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