Free BIMI Record Generator.

Enter your domain and the HTTPS address of your SVG logo above, add your certificate's address if you have one, and copy the TXT record the tool builds. Before you publish, make sure your DMARC policy is quarantine or reject and that your logo is an SVG Tiny PS file. Check And Generate tests both against your live DNS and the file itself, so you can fix problems before anything goes live.

Add it as a TXT record named default._bimi on your sending domain, so the full name is default._bimi.yourdomain.com. Many DNS panels add your domain automatically, so you type only default._bimi in the host field, while others want the full name; the tool shows both. Publish one BIMI record at that name: when there are two, providers use neither.

BIMI needs a DMARC policy of p=quarantine or p=reject, applied to all of your mail. A quarantine policy with pct below 100, or a record in testing mode with t=y, does not qualify, and neither does a subdomain policy of sp=none. The rule covers both the domain you send from and its parent domain, so a strict subdomain under a parent at p=none still fails.

You need one of them for Gmail and Apple Mail, but not for every provider. A Verified Mark Certificate (VMC) covers a registered trademark. A Common Mark Certificate (CMC) covers a logo you can show appeared on your own website at least 12 months ago, with no trademark needed. Gmail accepts both and adds a checkmark only with a VMC. Apple's documentation names the VMC, and Yahoo's guidance mentions no certificate.

A BIMI logo must be an SVG file in the SVG Tiny PS profile: version="1.2", baseProfile="tiny-ps" and one non-empty title. It cannot contain scripts, animation, embedded raster images or links to other files. It should be square, stay under 32 KB and sit on a solid background, and Gmail also asks for an absolute width and height of at least 96 pixels. Most design tools do not export this profile directly.

Yes, if it is already a vector SVG. Upload or paste it and the tool fixes what it safely can: the version and profile, a missing title, x and y on the svg element, scripts, editor metadata, inline styles, the size and padding to a square. Each fixed file is checked again and rendered beside your original before it is offered. A PNG or JPG cannot be converted faithfully, so start from your vector artwork.

Google says it can take up to 48 hours for BIMI to start working and for logos to appear in Gmail. DNS changes also need time to reach every resolver. Even then, providers decide message by message: Yahoo, for example, shows logos only for bulk mail from senders with enough reputation and engagement, so a new domain may wait longer.

Usually one of four things is wrong. DMARC is not enforced on your domain or its parent, the logo is not valid SVG Tiny PS, the logo inside your certificate differs from the file at your l= address, or the provider has not yet seen enough good mail from you. This tool checks the first three against your live DNS, your hosted file and your certificate.

No. The BIMI Group lists Microsoft as not supporting BIMI, so Outlook and Microsoft 365 mailboxes do not show your logo whatever you publish. The same list shows Apple, Google, Yahoo, Fastmail, La Poste and Zoho Mail among the providers that do. Gmail and Apple Mail also need a mark certificate before they show a logo.

No, not directly: BIMI does not change how spam filters score your mail. The DMARC enforcement it requires makes your domain harder to spoof, and a recognisable logo can help people spot your messages once they are already reaching the inbox. Delivery still depends on authentication, reputation and content, which an inbox placement test and a template check measure.
