What SVG Tiny PS logo files are#
SVG Tiny 1.2 Portable/Secure is the restricted SVG profile required by BIMI. It forbids scripts, external references, and embedded raster images, and requires a <title> element and baseProfile="tiny-ps".
Why it matters#
Providers reject non-conforming files silently. A valid file is the difference between a logo appearing or not.
How mailbox providers use it#
Gmail, Microsoft, and Yahoo combine authentication results, sender reputation, and recipient engagement into a placement decision made per message. SVG Tiny PS logo files feeds directly into that model, and weaknesses compound with other signals.
How to measure the impact#
- Baseline inbox placement with seed tests before any change.
- Make one change at a time and hold volume steady.
- Re-test after 48 to 72 hours; provider models need time to update.
- Track Postmaster Tools and SNDS alongside your seed results.
Improving it#
- 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.
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.
