SPF, DKIM and DMARC setup — for your exact registrar and mail provider

Most guides tell you what a TXT record is. These tell you exactly where to click in your registrar's DNS panel, what to paste, and which mistake breaks mail for half the people who try it alone. Twenty-eight combinations, written and kept current by a developer who fixes email authentication every week.

The full matrix

Every registrar × mail provider combination

All twenty-eight are published. Each carries its registrar's actual DNS panel path and field names, and its provider's real SPF include, DKIM selector type and activation step — not one article with the names swapped.

Need a combination that is not listed — a self-hosted mail server, a marketing platform like Mailchimp or Klaviyo alongside your mailbox? Ask us; those are the ones people get wrong most often.

Before you start

The three questions everyone asks first

Worth reading before you open your DNS panel — the second one is the mistake that causes most of the damage.

Yes. SPF lists which servers may send mail for your domain, DKIM cryptographically signs each message so it cannot be altered in transit, and DMARC tells the receiving server what to do when a message fails either check. Gmail and Microsoft now expect all three from anyone sending at volume, and a missing DMARC record alone is enough to put legitimate mail in the spam folder.
