What is BIMI VMC Certificate along with DMARC ?
Brand Indicators for Message Identification (BIMI) is a standardized way for inboxes
to display brand logos beside authenticated email securely and at scale. Verified Mark Certificates (VMCs) allow you to render your logo next to the “sender” field in email clients so that users see your mark—and that your organization has been authenticated—before they even open your message. While DMARC is Domain-based Message Authentication Reporting and Conformance is an accredited email authentication system developed to verify email authenticity by aligning the results of DKIM (Domain Keys Identified Mail) and SPF (Sender Policy Framework).
Pre-Requisites for BIMI/VMC Certificate
1). DMARC record needs to be placed in your domain’s dns with policy enforced either at quarantine or reject stage(p=quarantine or p=reject). if it’s at none stage i.e. p=none then you can not apply for BIMI. BIMI Records needs to be placed in domains DNS as TxT record.
2). Your Logo must be Trademarked.
3). Your logo must be in SVG Tiny 1.2 format only.
4). While creating an SVG images these points needs to be noted:
- Image size should be less then 32KB
- Must include a <title> element and reflect your company name
- The following namespace needs to be allowed at a minimum: svg: http://www.w3.org/2000/svg. We recommend that only the svg namespace should be added in the <svg> tag.
Example: <svg version=”1.2″ baseProfile=”tiny-ps” viewBox=”0 0 200 200″ xmlns=”http://www.w3.org/2000/svg”> <svg>
- SVG Version: 1.2 with baseProfile as “tiny-ps”
- remove any x or y if it’s coming
5). Purchase a VMC certificate from CA, depending upon how many domains/sub-domains or different logo’s are required. CA or its partner would be able to assist in this.
6). Add the certificate as provided by CA in DNS and your logo would be displayed right next to every email.
