Email deliverability checker

Find out if your domain is set up to reach the inbox. Live SPF, DKIM, DMARC, MX and blacklist checks, scored 0–100 in seconds.

What the checker looks at

Gmail, Yahoo and Microsoft now require authenticated mail from anyone sending in volume. These five checks are what they look at first.

SPF

20 pts

Is there exactly one SPF record, does it end in ~all or -all, and does it stay under the 10-lookup limit?

DKIM

20 pts

Is a DKIM public key published? We probe the common selectors (Google, Microsoft, most ESPs), or the one you give us.

DMARC

20 pts

Is there a DMARC record, and is its policy enforced (quarantine or reject) or only monitoring (none)?

MX

15 pts

Can the domain receive mail? Replies and bounces need somewhere to land, and spam filters notice when they can't.

Blacklists

25 pts

Is your mail server's IP listed on Spamhaus ZEN or Barracuda? A list that doesn't answer is reported as unknown, never as clean.

Authentication gets you in the door. Reputation decides inbox or spam, and that's what warmup builds.
