But it&rsquo;s not just cosmetic:</p> <ul> <li><strong>Trust</strong>: a verified logo increases recipient confidence</li> <li><strong>Open rates</strong>: studies show a 10-30% increase in opens</li> <li><strong>Anti-spoofing</strong>: BIMI requires DMARC at <code>quarantine</code> or <code>reject</code>, which blocks spoofing</li> <li><strong>Brand visibility</strong>: your logo appears before the message is even opened</li> </ul> <h3 id="who-supports-bimi">Who Supports BIMI?</h3> <table> <thead> <tr> <th>Client / ISP</th> <th>BIMI Support</th> <th>VMC Required?</th> </tr> </thead> <tbody> <tr> <td>Gmail</td> <td>✅ Yes</td> <td>✅ Yes</td> </tr> <tr> <td>Apple Mail (iOS 16+, macOS Ventura+)</td> <td>✅ Yes</td> <td>❌ No</td> </tr> <tr> <td>Yahoo / AOL</td> <td>✅ Yes</td> <td>❌ No</td> </tr> <tr> <td>La Poste</td> <td>✅ Yes</td> <td>❌ No</td> </tr> <tr> <td>Outlook</td> <td>🔄 In progress</td> <td>,</td> </tr> <tr> <td>Fastmail</td> <td>✅ Yes</td> <td>❌ No</td> </tr> </tbody> </table> <blockquote> <p>Gmail is the only one requiring a VMC (Verified Mark Certificate).
