BIMI
Also called: Brand Indicators for Message Identification
BIMI (Brand Indicators for Message Identification) is a DNS record that lets participating mailbox providers show your logo next to your emails, once your domain is protected by DMARC at enforcement.
The BIMI Group’s guide requires DMARC at enforcement on the organisational domain and subdomains (quarantine or reject; none or a pct below 100 isn’t accepted), a logo in SVG Tiny PS format, and recommends a Verified Mark Certificate (VMC) or Common Mark Certificate (CMC). It notes that self-asserted records have limited support and that each provider sets its own criteria (BIMI Group).
How it affects cold email
BIMI isn’t required for cold email and won’t fix deliverability on its own. The part that helps is the prerequisite: a DMARC policy at enforcement. A logo can make an email from an unknown sender look more trustworthy, but cold emails that look like personal notes don’t need one.
How Inboxed handles it
- Inboxed doesn’t publish or check BIMI records. If you set BIMI up for your domain, mail sent through Inboxed from that domain is treated the same as any other mail from it.
