SPF and DMARC record generator

Two DNS records stop scammers sending email that looks like it's from your domain. Answer three questions and copy the records into your DNS settings. Free, and nothing you enter is stored.

What these records do

SPF lists the services allowed to send email as you. DMARC tells Gmail, Outlook and the rest what to do with email that fails: deliver it, send it to spam, or block it. DKIM, which your email provider switches on, signs your real email. Our email spoofing guide explains all three and the mistakes to avoid.
