Email domain checker
Runs every check at once. Use this one if you are not sure what is wrong — it looks at SPF, DMARC and your mail servers together, which is how a receiving server sees you.
Why check all three together
Authentication is judged as a whole. A perfect SPF record does not help if DMARC is absent, and a strict DMARC policy will reject your own mail if SPF and DKIM are not aligned. Looking at one at a time is how setups end up internally inconsistent.
What good looks like
An SPF record well inside the ten-lookup limit ending in ~all or -all; a DKIM key published and not in test mode; a DMARC policy at quarantine or reject with an rua address collecting reports. If all three are true, you have done more than most senders.
If you are about to send a campaign
Fix authentication before volume, not after. Reputation is slow to build and fast to lose, and the first large send from an unauthenticated domain is the one that teaches every receiver to distrust you.
Authentication set up for you
Add a domain in Pigeonify and we generate the SPF, DKIM and DMARC records, then verify them for you. Free up to 5,000 emails a month.
