Providers reject non-conforming files silently. A valid file is the difference between a logo appearing or not.
How to implement SVG Tiny PS logo files#
- Export a square SVG with the logo centered and a solid background color.
- Set baseProfile="tiny-ps" and version="1.2" on the root svg element.
- Add a <title> element matching your brand name.
- Remove all script, filter, and external href references, and strip x/y attributes from the root.
- Validate with a BIMI SVG converter and keep the file under 32 KB.
How to verify it worked#
Send a test message to seed mailboxes at Gmail, Outlook, and Yahoo, then inspect the Authentication-Results and delivery headers. Repeat after any DNS or sending-platform change.
Common mistakes#
- Transparent backgrounds, which render unpredictably on dark-mode clients.
- Text elements that rely on fonts; convert text to outlines.
Frequently asked questions#
Why does my SVG fail validation?
Most commonly a missing baseProfile attribute, embedded images, or leftover editor metadata. Run it through a converter that outputs the Tiny PS profile.
