Authentication

What is BIMI?

BIMI (Brand Indicators for Message Identification) is a DNS record that lets supporting mailbox providers show your brand logo next to your emails. It requires an enforced DMARC policy.

Also called: Brand Indicators for Message Identification

Updated

BIMI puts your logo where the sender avatar would be. It is a reward for authenticating properly, and a small piece of branding in a crowded inbox.

What you need

  1. Enforced DMARC. The policy must be quarantine or reject. p=none is not enough.
  2. A logo in a specific SVG format, hosted at an HTTPS address.
  3. A DNS record at default._bimi.yourdomain.com that points to the logo.
  4. A certificate, for the mailbox providers that require one. This is a verified or common mark certificate, issued after the provider checks your trademark or use of the logo.

The record looks like this:

v=BIMI1; l=https://example.com/logo.svg; a=https://example.com/cert.pem

BIMI and Amazon SES

BIMI is configured in DNS and judged at the receiving end, so SES has no BIMI settings. If your mail from SES passes an enforced DMARC policy, it is eligible like any other mail. The work is on your domain’s side.

Should you bother

Only after the basics are solid. A logo in the inbox helps people recognise mail they want, and that can help engagement. It will not rescue a poor sender reputation, and it takes real effort: enforcement, a correct SVG and usually a certificate. Many senders skip it, and that is a reasonable choice.

See DMARC policy for how to reach enforcement without blocking your own mail.

Common questions

Is BIMI worth it?

It makes your mail easier to recognise, and it is a visible reward for authenticating well. It does not improve deliverability by itself, so set up SPF, DKIM and DMARC first.

Does every inbox show BIMI logos?

No. Support varies by mailbox provider, and some require a verified mark certificate before they show a logo.
