Configured SPF, DKIM, and DMARC are no longer a luxury — they're a requirement for landing in the inbox. But even correct authentication doesn't guarantee that an email will be noticed and opened. BIMI adds a visual identifier to technical protection: an official logo next to the email. This isn't a decorative detail — it's a tool for boosting trust and click-through rates.

BIMI (Brand Indicators for Message Identification) is a standard that lets email clients display a verified sender logo in the inbox list. BIMI requires: correct SPF and DKIM, a strict DMARC policy (quarantine or reject), a logo file in SVG-Tiny format, and proof of trademark ownership.

How it works — technically

  1. SPF and DKIM are enabled at the domain level.
  2. DMARC is set with a quarantine or reject policy.
  3. A logo is prepared in SVG-Tiny format that meets the requirements.
  4. A certificate of logo ownership is obtained.
  5. A BIMI DNS record is published, pointing to the logo/VMC.If the email client supports BIMI and all checks pass, the logo appears next to the email.

Why BIMI affects deliverability and metrics

  • Open rate. Having a logo increases the likelihood of an email being opened thanks to instant visual identification. In some case studies and research, open-rate growth has reached double digits.
  • Sender reputation. Configuring all authentication protocols and publishing BIMI signals to mail providers that you take security seriously — this reduces the chance of landing in spam.
  • Reduced fraud risk. The visual mark helps users distinguish official emails from fakes, which reduces complaints and erosion of trust.

A logo in the inbox list works like a mini-ad: even without opening the email, the user sees your brand. This is especially valuable for companies in high-distrust segments (banks, fintech, e-commerce): the visual mark increases the chances of instant recognition and a click.

  • Open rate and CTR can grow thanks to a visible logo.
  • For large brands, BIMI helps reduce the number of phishing fakes, saving resources on support and reputation recovery.

What's needed to implement it — a step-by-step checklist

  1. Check SPF: the sender domain includes the required IPs/authorized senders.
  2. Set up DKIM and make sure the signatures pass verification.
  3. Set DMARC to quarantine or reject and monitor reports.
  4. Prepare an SVG-Tiny logo according to BIMI requirements.
  5. Obtain a VMC from an accredited authority (usually requires trademark registration).
  6. Publish the BIMI record in DNS and specify the logo or VMC URL.
  7. Send a test email and check the display in major email clients.
  8. Track metrics: deliverability, open rate, CTR, complaints/unsubscribes.

If email is an important part of sales or communications and your brand cares about protection from fakes, BIMI is worth implementing. This is especially relevant for services where trust directly affects conversions: fintech, online retail, SaaS.

BIMI adds a visible trust mark to an already configured authentication system. It's an effective tool: it boosts recognition, increases open rates, and makes it easier for users to identify official messages. Implementation requires technical steps and proof of logo ownership, but delivers measurable benefits in email communications.
