BIMI: definition
BIMI (Brand Indicators for Message Identification) is a standard for displaying a sender's logo in the inbox. The domain publishes a DNS TXT record, usually at default._bimi.domain, with v=BIMI1, an l= tag pointing to the logo in the SVG Tiny Portable/Secure (SVG Tiny PS) format, and optionally an a= tag pointing to a mark certificate.
BIMI only works on top of authentication: the message must pass DMARC, and the domain's DMARC policy must be at enforcement (quarantine or reject), not p=none. Some mailbox providers, including Gmail, also require a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC) before they show the logo.
Why it matters
BIMI is mostly a brand and trust signal for marketing and transactional mail. For cold outreach it's rarely a priority: many outreach teams send from separate domains, and the work of reaching DMARC enforcement matters more than the logo itself. It's worth doing on your main domain once SPF, DKIM and DMARC are solid.
How Skrap.ai helps
Skrap.ai has nothing to do with BIMI: it doesn't set up records, logos or certificates. What it does is keep your sending lists clean, through the free email verifier and bulk verification, so the domain you've authenticated keeps a good record.
