SPF, DKIM and DMARC Record Generator

Make the three DNS records that tell inboxes your email is really from you.

Runs in your browser. Nothing you type is stored or sent.

Your domain

Who sends email for you?

Other senders (domains or IP addresses)Mail from anyone else

SPF

TypeTXTHost / name@ (or your domain)Valuev=spf1 include:_spf.google.com ~all

1 of 10 DNS lookups used.

DMARC

PolicyApply to 100% of mailSend reports to (email)

TypeTXTHost / name_dmarc.yourdomain.comValuev=DMARC1; p=none; adkim=r; aspf=r

Start with none, read the reports for 2 weeks, then move to quarantine and reject.

DKIM

Selector (from your email provider)Public key (paste it from your provider)

Your provider makes the DKIM key (Google: Admin console > Apps > Gmail > Authenticate email). Paste its public key above to get the record.

Add each record in your domain's DNS (where you bought the domain, or Cloudflare). Then check them with the DNS Checker in this studio.

Questions

Do I need all three?

Yes. Since 2024 Google and Yahoo expect SPF, DKIM and DMARC from anyone sending in bulk, and they help every sender reach the inbox.

Which DMARC policy should I start with?

p=none, to collect reports without blocking anything. Move to quarantine, then reject, once the reports look clean.

Is my data sent anywhere?

No. This runs in your browser, so what you type stays on your device.

About the SPF, DKIM, DMARC

The SPF, DKIM and DMARC generator makes the DNS records that prove your email is really from you. Since 2024, Gmail and Yahoo require them for bulk senders, and without them your email is far more likely to land in spam.

When to use it

Set up email for a new domain.
Add a new sending service such as Mailchimp or HubSpot to SPF.
Start DMARC reporting before moving to a strict policy.

Tips for a better result

Start DMARC at p=none, read the reports, then move to quarantine.
Keep SPF under 10 lookups.
