If your open rates have plateaued and your subject lines are already good, the problem might not be your content. It might be that people do not recognize you in the inbox before they decide whether to open.

That is the gap BIMI closes. And if you run your email on Zoho Mail, you already have most of the tooling to set it up.

What BIMI actually does

BIMI (Brand Indicators for Message Identification) displays your verified brand logo next to your name in the inbox, before the email is even opened. It shows up in Gmail, Yahoo, Apple Mail, and Zoho Mail, and in several of those it comes with a verified checkmark beside your sender name.

A Yahoo Mail pilot run by Verizon Media found that senders using BIMI saw an average 10% increase in open rates. Later research from Red Sift and Entrust reported open rate lifts as high as 21%, along with a 90% jump in consumer confidence that an email was legitimate.

BIMI is not a logo upload, it is a reward for authentication

This is the part that surprises people. You cannot just publish a logo and switch BIMI on. BIMI is the payoff for getting your email authentication right first.

Before BIMI will display anything, you need:

  • SPF and DKIM passing for every system that sends mail as your domain
  • DMARC at enforcement, meaning p=quarantine or p=reject with pct=100. A p=none policy will not work.
  • A compliant SVG logo in the SVG Tiny PS profile
  • A certificate, either a VMC or a CMC, hosted publicly and referenced in your BIMI DNS record

DMARC enforcement is where most people get stuck. Move to enforcement too fast and legitimate mail gets quarantined. Sit at p=none forever and the logo never appears. The safe path is to run p=none first, read your DMARC reports for a few weeks to catch every legitimate sender, then move to quarantine, then reject.

Setting up BIMI in Zoho Mail, step by step

The good news for Zoho users is that the Admin Console handles MX, SPF, DKIM, DMARC, and BIMI in one place. Here is the flow.

  1. Configure MX, SPF, and DKIM. In the Zoho Mail Admin Console, go to Domains, select your domain, and open Email Configuration. Zoho generates the SPF and DKIM records for you to add to your DNS, then verify them.
  2. Set DMARC to enforcement. Use Zoho’s DMARC generator in the same Email Configuration area. Set the policy to quarantine or reject and the percentage to 100, publish the record in your DNS, and confirm it verifies.
  3. Prepare your logo. Convert your logo to an SVG in the BIMI Tiny PS profile, with baseProfile set to tiny-ps and version set to 1.2. Keep it square and centered, and make it at least 96 by 96 pixels with absolute dimensions, since Gmail enforces that. Host the SVG on a public HTTPS URL.
  4. Get and host your VMC. Zoho’s BIMI setup expects a Verified Mark Certificate, which requires your logo to be a registered trademark. Obtain it from an accredited authority such as DigiCert, then host the PEM file on a public URL.
  5. Generate the BIMI record in Zoho. In the Admin Console, go to Domains, select your domain, open Email Configuration, and choose BIMI. Enter your logo URL and your VMC URL, then click Generate. Zoho produces the BIMI TXT record.
  6. Publish and verify. Add the generated record as a TXT entry at default._bimi.yourdomain.com in your DNS, then return to the Admin Console and click Verify BIMI record. Go to https://mxtoolbox.com/bimi.aspx to test.

Test before you celebrate

DNS and mailbox caches mean your logo will not appear instantly. Give it time to propagate, then send test emails to Gmail, Yahoo, and Zoho accounts and confirm the logo renders. Keep an eye on your DMARC reports afterward so a new sending source does not quietly break alignment later.

The takeaway

BIMI is one of the higher-leverage things you can do for email trust, and on Zoho the setup is more guided than most people expect. The logo is the visible part. The real win is the clean authentication underneath it, which protects your domain from spoofing whether or not anyone ever notices the logo.
