SPF, DKIM and DMARC explained in simple words

Mail systems check if an email really comes from you. Three records help.

SPF

A TXT record listing the servers allowed to send email for your domain.

v=spf1 +a +mx include:_spf.yourhost.com ~all

DKIM

A digital signature added to each email. The receiver checks it against a public key in your DNS. It proves the message was not changed.

DMARC

Tells receivers what to do when SPF or DKIM fail, and sends you reports.

v=DMARC1; p=none; rua=mailto:you@yourdomain.com

Start with p=none, read the reports, then move to quarantine or reject.

Why it matters

Without these records, your mail often goes to spam and criminals can send fake mail in your name. Add the records in your DNS panel: DNS records explained.
