What does BIMI need before a logo shows?

A BIMI TXT record at default._bimi. pointing at an SVG Tiny PS logo over HTTPS, and DMARC at enforcement (p=quarantine or p=reject at pct=100) for the domain and its organizational domain. Gmail also needs a Verified Mark Certificate or Common Mark Certificate, and Apple Mail a Verified Mark Certificate.

Does BIMI improve deliverability?

Not by itself: it displays a logo on mail that already passes DMARC. The work it requires, getting DMARC to enforcement, is what protects deliverability.

Can I use BIMI without a certificate?

Yes, with providers that do not require one, such as Yahoo. Gmail and Apple Mail show the logo only with a mark certificate.
