Check and fix your domain (SPF, DKIM, DMARC)
Email providers look at three records of your domain before letting an email through. Secuenza checks them and tells you how to fix what’s missing.
What is checked
For each mailbox, the checks tab reviews:
- SPF: which servers may send on behalf of your domain.
- DKIM signature: that your emails are signed and the key is long enough.
- DMARC: what providers should do with an email that fails the other two.
- Mail reception (MX), reverse DNS (PTR), MTA-STS, BIMI and connection encryption.
Each check shows green, amber or red, with an explanation in plain language.
How to fix it
When something fails, Secuenza tells you which record to add and where, with the steps for your provider. If you’d rather have an AI explain it, Copy prompt for AI prepares the question with your details.
DNS changes take a while to show: check again after an hour.
With Pro
