Question 1

What is domain health for email?

Accepted Answer

Domain health measures how correctly a sending domain is configured for email authentication and reputation. The core signals are the SPF, DKIM, and DMARC DNS records that prove your mail is legitimate, whether the domain has valid MX records, and whether it appears on any email blocklists. A healthy domain has all three auth records set up and enforcing, resolvable MX, and no blocklist listings — which is what mailbox providers like Gmail and Outlook look for before delivering to the inbox instead of spam.

Question 2

How do I check my email domain health?

Accepted Answer

Enter your domain into this free Domain Health Check and it queries your live DNS in real time: it looks up your SPF record, probes common DKIM selectors, reads your DMARC policy, checks your MX records, and tests the domain against public blocklists. Each check is scored pass, warn, or fail and rolled into a single 0-100 health score, with a one-line fix and a link to the right generator for anything that fails. No signup is required.

Question 3

What is a good SPF, DKIM, and DMARC setup?

Accepted Answer

A good setup has exactly one SPF record that lists every service that sends on your behalf and ends in "-all" (hard fail); a DKIM key published at a selector for each sending service with a valid, non-revoked public key; and a DMARC record with an enforcing policy of "p=quarantine" or "p=reject" plus a "rua" address so you receive aggregate reports. SPF and DKIM prove the mail is authentic, and DMARC tells receivers what to do when a message fails — together they are what earns inbox placement.

Question 4

Is this domain health checker free?

Accepted Answer

Yes. MailPilot’s Domain Health Check is completely free with no signup. It runs live SPF, DKIM, DMARC, MX and blocklist checks and returns a health score in seconds. MailPilot’s full platform then continuously monitors these signals — plus warms your mailboxes and tracks inbox placement — and has a free plan, with paid plans from $9/month.
