Free tool · Email deliverability

Do your emails reach the inbox?

Since February 2024, Gmail and Yahoo require SPF, DKIM and DMARC from anyone sending 5,000 or more emails a day to their users. Enter your domain to see which records you have, what each one does and the record to add if one is missing.

In short

How do I check SPF, DKIM and DMARC for my domain?

Enter your domain in the email deliverability check. In under 5 seconds it reads your public DNS records and shows whether SPF, DKIM, DMARC, MX and BIMI are set, counts SPF’s 10-lookup limit, checks them against the Gmail and Yahoo sender rules, and gives you a starter record to paste for anything missing.

01 — What it checks

The records every inbox reads.08

Before an inbox shows your campaign, it looks up three records on your domain. Here’s each one, and the details that break them.

  • SPF

    Which servers may send as you. One record only, with an ending that tells inboxes what to do with the rest.

  • SPF lookup limit

    Every include: costs DNS lookups; past 10, SPF fails. We follow the includes and count.

  • DKIM

    The signature that proves an email wasn’t changed. We look up the selectors you enter, or the common ones.

  • DKIM key size

    1024-bit keys still pass, but 2048-bit is today’s standard. We size every key we find.

  • DMARC policy

    What inboxes do with mail that fails: nothing, spam folder or reject. p=none only monitors.

  • DMARC reports

    A rua= address, so you see every service that sends as you, and when one starts failing.

  • Mail servers

    MX records, so replies to your campaigns don’t bounce, and which provider handles them.

  • BIMI

    The optional record that shows your logo next to your emails, once DMARC is enforced.

02 — How it works

Three lookups, one answer.

  1. We ask public DNS

    Over encrypted DNS (Cloudflare’s resolver, with Google’s as backup), for the same records every inbox reads.

  2. We read each record

    SPF includes are followed and counted, DKIM keys are sized, and the DMARC policy and reports are read tag by tag.

  3. You get the record to add

    Each check gets pass, warn or fail, and a missing record comes with a starter version to paste into your DNS.

What a record check can’t see

Whether mail lands in the inbox or spam, your sender reputation, list hygiene and how your campaigns are built. A deliverability audit tests those with real sends.

Questions about email records.

Not on the list? Ask on a call, or by email.

The name a sending service gives its DKIM key, like “google” for Google Workspace or “k1” for Mailchimp. You’ll find it in the domain settings of each tool that sends as you. Enter several, separated by commas.
