BIMI Logo Checker

BIMI puts your company logo next to your emails in Gmail, Yahoo and Apple Mail. Check that your logo file meets BIMI's strict format, fix the common problems in one click, and check that your domain is set up for it.

1. Check your logo file

BIMI logos need a title. Used by "Fix it for me".

2. Check your domain

What you need for a BIMI logo

  1. DMARC at enforcement. Your domain's DMARC policy must be p=quarantine or p=reject, applied to all mail. A p=none policy doesn't qualify. The DMARC generator builds the record.
  2. A logo in SVG Tiny PS format. A special, locked-down kind of SVG: square, with a title, and no scripts, animation, outside links or embedded photos. This page checks all of that and fixes most of it.
  3. The logo on your website at an https address, for example https://yourcompany.com/bimi/logo.svg.
  4. A BIMI record in your DNS: a TXT record named default._bimi pointing to the logo.
  5. A mark certificate (VMC or CMC) for Gmail and Apple Mail. It's a paid certificate from companies like DigiCert or Sectigo that proves the logo is yours. Yahoo can show your logo without one.

The BIMI DNS record

Add a TXT record with the name default._bimi and this value, using your own logo address:

v=BIMI1; l=https://yourcompany.com/bimi/logo.svg; a=https://yourcompany.com/bimi/certificate.pem

Leave a= empty (a=;) until you have a mark certificate.

Designing a logo that looks good in BIMI

Inboxes show BIMI logos small and cropped to a circle, sometimes on a dark background. Use a simple mark or monogram rather than a wide wordmark, keep it centred with some space around the edges, and give it a solid background colour so it doesn't vanish in dark mode. The previews above show the circle crop at real sizes.

What the BIMI logo checker does

BIMI lets inboxes like Gmail, Yahoo and Apple Mail show your company logo next to your emails, but the logo file has to follow a strict SVG format and your domain needs the right DNS records. This tool checks your SVG logo against those rules, fixes most problems for you, and looks up your BIMI and DMARC records. It saves you from guessing why your logo isn't showing up.

Benefits

  • Upload or paste your logoDrop in an .svg file or paste the SVG code straight from your design program.
  • Clear checklist of problemsEvery rule gets an OK, Note or Problem label: version, baseProfile, title, square shape, scripts, animation, outside links, embedded images, file size and background.
  • Fix it for meOne click adds the right version and profile, adds your company name as the title, makes the logo square, and strips scripts, animation, outside links and editor clutter.
  • Download or copy the fixed fileSave the cleaned logo as an SVG file or copy the code to paste wherever you need it.
  • See how it will lookPreviews show the logo cropped to a circle at inbox, dark mode, opened email and large sizes.
  • Checks your domain tooIt reads your default._bimi and DMARC records and tells you if your policy is strict enough, if pct is below 100, and whether a mark certificate is listed.
  • Loads the logo from your recordIf your BIMI record points to an https logo, the tool tries to load it and check it automatically.
  • Honest about what it can't fixAn embedded PNG or JPG can't be turned into vector shapes, and the tool tells you to get the original vector file from your designer.

Who it is for

  • Small-business owners who want their logo to appear next to their emails.
  • Web designers preparing a client's logo for BIMI without hand-editing SVG code.
  • Marketing teams checking why their logo isn't showing in Gmail or Yahoo.
  • IT admins confirming DMARC and BIMI records are in place before buying a mark certificate.
  • Freelancers who set up email authentication for clients and need a quick check.

How to use it

  1. Upload your SVG logo or paste its code, and type your company name.
  2. Read the checklist and look at the circle previews.
  3. Click Fix it for me if there are problems, then download or copy the fixed logo.
  4. Enter your domain and click Check domain to review your BIMI and DMARC records.

Your privacy

Your logo is checked and fixed in your browser and is not uploaded to ListaFix. The domain check asks Cloudflare's public DNS (or Google's as a backup) for your public BIMI and DMARC records, and your browser may try to load the logo from the address in your BIMI record.

Frequently asked questions

What is BIMI?

Brand Indicators for Message Identification. It lets email providers like Gmail, Yahoo and Apple Mail show your company logo next to your emails, once your domain is protected by DMARC.

What is SVG Tiny PS?

A strict, simplified version of the SVG image format required for BIMI logos. It must be square, include a title, and contain no scripts, animation, external links or embedded photos.

Do I need a VMC certificate for BIMI?

For Gmail and Apple Mail, yes: they require a paid mark certificate (VMC, or CMC for Gmail). Yahoo can show a BIMI logo without one if your domain has a good sending reputation.

Why isn't my BIMI logo showing in Gmail?

The usual reasons: no mark certificate, DMARC still at p=none or below 100%, the SVG isn't in Tiny PS format, or the logo URL isn't reachable over https. This page checks the logo, the BIMI record and DMARC.

Can I convert a PNG logo to BIMI SVG here?

No. A BIMI logo must be drawn as vector shapes. An SVG that just wraps a PNG or JPG inside isn't allowed. Ask your designer to export the original vector logo as SVG, then fix it here.

Is my logo uploaded?

No. The logo is checked in your browser. The domain check looks up your public DNS records, and your browser then loads the logo from the address in your BIMI record.
