SPF & DMARC record generator

Build the DNS records that keep your cold email out of spam. Answer a couple of questions and copy the record straight into your DNS. Runs entirely in your browser.

SPF record

Lists the services allowed to send email for your domain. Tick every one you use.

What should happen to mail that fails the check?

TypeTXTHost / Name@ (your root domain)
v=spf1 ~all

DMARC record

Tells inbox providers what to do with mail that fails checks, and where to send reports.

Policy

TypeTXTHost / Name_dmarc
v=DMARC1; p=none; pct=100

Start on Monitor only to watch the reports without affecting delivery, then move to Quarantine and Reject once you know your legitimate mail passes.

Cadivra checks all of this for you.

When you send from your own mailbox, Cadivra scans your SPF, DKIM and DMARC and watches the major blocklists, so deliverability problems surface before you send, not after. Start free with 100 credits - no card required.
