BIMI (Brand indicators for message identification)
BIMI lets you display your brand logo next to emails by adding a DNS record pointing to an SVG file of your logo. Gmail and several other providers support it, with caveats:- To guarantee your logo appears in Gmail, you need a Verified Mark Certificate (VMC): a third-party certification that costs around 200/year.
- Without a VMC, some clients may still show your logo, but support is inconsistent.
