Brand Identity • BIMI Standard • VMC Certificate

Free BIMI Record Generator & SVG Validator

Construct an official BIMI DNS TXT record to display your verified company logo next to emails in Gmail, Apple Mail, and Yahoo.

Quick Answer • Standard BIMI Record Syntax

BIMI records are published at default._bimi.yourdomain.com as a DNS TXT record with value v=BIMI1; l=https://yourdomain.com/logo.svg; a=https://yourdomain.com/vmc.pem;. DMARC enforcement (p=quarantine or p=reject) is mandatory for BIMI eligibility.

1. The Evolution of Brand Indicators for Message Identification (BIMI)

Brand Indicators for Message Identification (BIMI) is an email ecosystem specification that enables organizations to display their official trademarked logo directly within the inbox UI of major email clients, including Gmail, Apple Mail on iOS/macOS, Yahoo Mail, and Fastmail.

Unlike proprietary avatar solutions (such as Gravatar or Google Account profile photos), BIMI is tied directly to cryptographic email authentication standards (SPF, DKIM, and DMARC). For a mailbox provider to render a BIMI logo, the message must achieve 100% DMARC identifier alignment and originate from a domain enforcing strict anti-spoofing policies (p=quarantine or p=reject).

2. The SVG Tiny Portable/Secure (P/S) Formatting Specification

Standard SVG files containing scripts, external fonts, or bitmap imagery pose security and rendering risks. Mailbox providers strictly enforce the SVG Tiny P/S profile:

Square 1:1 Aspect Ratio: The image dimensions must be perfectly square (e.g. 512x512).
viewBox Declaration: Must include a valid viewBox="0 0 512 512" attribute.
Zero External Dependencies: All paths and vector shapes must be self-contained within the SVG file.
Strict 32 KB File Limit: The uncompressed SVG file should not exceed 32 kilobytes in total size.

3. Frequently Asked Questions (BIMI & VMC Engineering FAQ)

What is BIMI and why is it important?

BIMI (Brand Indicators for Message Identification) is an email standard that allows authenticated senders with DMARC enforcement to display their official trademarked logo next to inbound messages in major mailboxes (Gmail, Apple Mail, Yahoo Mail). It drives higher open rates, reinforces brand recognition, and protects customers against visual phishing.

Do I need a Verified Mark Certificate (VMC) for BIMI?

For Gmail and Apple Mail, a VMC issued by an authorized CA (such as DigiCert or Entrust) is mandatory. Yahoo Mail supports self-asserted BIMI without a VMC for senders with exceptional domain reputation, but acquiring a VMC is strongly recommended for universal display.

What are the exact SVG requirements for a BIMI logo?

The logo must conform to the SVG Tiny Portable/Secure (SVG Tiny P/S) profile. Requirements include: 1:1 square aspect ratio, centered graphics, viewBox attribute present, no embedded raster images (PNG/JPEG), no external font or script references, and file size under 32 KB.

Why is DMARC p=none not supported for BIMI?

BIMI is a reward mechanism for organizations that protect their domain from spoofing. Because p=none provides zero anti-spoofing protection, mailbox providers mandate active enforcement (p=quarantine with pct=100 or p=reject) before rendering brand logos.

Where is the BIMI DNS record published?

A BIMI record must be published as a DNS TXT record at default._bimi.yourdomain.com (or using a custom selector e.g. promo._bimi.yourdomain.com).

How long does it take for Gmail to display my BIMI logo after DNS deployment?

Once DNS propagates and VMC certificates are validated, mailbox providers usually take between 48 hours and 2 weeks to begin rendering logos in inboxes, depending on sending volume and sender reputation history.
