SPF authorizes sending servers, DKIM signs messages cryptographically, and DMARC ties both to your visible From address with a policy and reporting. A plain-English comparison of all three DNS records, the exact syntax, the 10-lookup limit, alignment rules, and the staged rollout order that gets you to p=reject without blocking your own mail.
BIMI puts your brand logo next to your emails in supporting inboxes, but only after DMARC enforcement and a verified mark certificate. Here is what BIMI requires, how to publish the record, how to prepare an SVG Tiny PS logo, where it actually renders, and how to decide whether the annual certificate cost is worth it for your sending program.
SPF, DKIM, and DMARC explained without the jargon. See what each DNS record does, how they work together, and the safe order to roll them out.
