Frequently Asked Questions

What is BIMI?

BIMI (Brand Indicators for Message Identification) is an email standard that displays your brand logo next to your emails in supported inboxes like Gmail and Yahoo. It requires DMARC enforcement and an SVG logo.

Do I need a VMC for BIMI?

VMC (Verified Mark Certificate) is required by Gmail but optional for some other providers. It proves trademark ownership and costs around $1,000-1,500/year from providers like DigiCert or Entrust.

What are SVG Tiny P/S requirements?

BIMI logos must use SVG Tiny Portable/Secure format: no JavaScript, no external references, no animations, square aspect ratio, and under 32KB file size.

Why isn't my BIMI logo showing?

Common issues: DMARC policy not set to quarantine/reject, SVG not in Tiny P/S format, logo not accessible via HTTPS, or missing VMC for Gmail.

Which email providers support BIMI?

Gmail, Yahoo, Apple Mail, and Fastmail support BIMI. Gmail requires VMC, while others may show logos without it. Support is growing across providers.

Understanding BIMI: The Complete Guide

BIMI (Brand Indicators for Message Identification) is an email specification that allows organizations to display their brand logo next to authenticated emails in recipients' inboxes. It's the visual reward for implementing strong email authentication and provides immediate brand recognition while building trust with recipients.

How BIMI Works

BIMI connects your brand logo to your email authentication:

  1. You publish a BIMI record in DNS at default._bimi.yourdomain.com
  2. The record points to your logo (SVG format) and optionally a VMC certificate
  3. When you send an authenticated email (DMARC pass with p=quarantine or p=reject), the receiving mail client fetches your logo
  4. Your logo appears next to your email in the recipient's inbox

BIMI Requirements

Before implementing BIMI, you must have:

  • DMARC at enforcement - Your DMARC policy must be p=quarantine or p=reject (not p=none)
  • SPF and/or DKIM passing - At least one must pass with alignment for DMARC to pass
  • SVG Tiny PS logo - Your logo must be in SVG Tiny Portable/Secure format (not standard SVG)
  • Square logo - The logo must be square with a centered design

VMC Certificates Explained

A Verified Mark Certificate (VMC) is a digital certificate that verifies your organization owns the trademark for your logo. While not all email providers require VMC, Gmail does.

  • Gmail - Requires VMC for logo display
  • Yahoo/AOL - Displays logos without VMC
  • Apple Mail - Supports BIMI without VMC
  • Fastmail - Supports BIMI without VMC

VMC certificates are issued by certificate authorities like DigiCert and Entrust, and require proof of trademark registration.

Creating a BIMI-Compliant Logo

Your logo must meet specific technical requirements:

  • Format - SVG Tiny 1.2 Portable/Secure (not standard SVG)
  • Dimensions - Square aspect ratio, centered design
  • Background - Solid background color (no transparency)
  • File size - Under 32KB recommended
  • No scripts - Must not contain JavaScript or external references

Use BIMI logo generators or converters to ensure your logo meets these requirements.

BIMI Record Syntax

A BIMI record is a DNS TXT record with the following format:

  • Basic (no VMC): v=BIMI1; l=https://example.com/logo.svg;
  • With VMC: v=BIMI1; l=https://example.com/logo.svg; a=https://example.com/vmc.pem;

The logo URL must be HTTPS and publicly accessible.

Benefits of BIMI

  • Brand visibility - Your logo appears prominently in crowded inboxes
  • Trust signal - Recipients can visually verify legitimate emails from your brand
  • Phishing protection - Makes it harder for attackers to impersonate your brand
  • Higher engagement - Studies show BIMI can increase open rates by 10%+
