Summary
Implementing BIMI involves a multi-step process. Proper DNS setup is essential, with the BIMI record under `default._bimi`. The SVG logo must meet specific criteria. A VMC is often required (Gmail), though some providers (Yahoo) offer alternatives based on reputation. Strong authentication (SPF, DKIM, DMARC - enforced at p=quarantine or p=reject) is critical. Collaboration between marketing and IT, thorough testing, and ongoing monitoring are best practices. Success boosts brand recognition and trust.
Key findings
- VMC Necessity Varies: While Gmail requires a VMC for BIMI logo display, other providers, like Yahoo, may offer support without one based on sender reputation and adherence to guidelines.
- DNS Record Placement: The BIMI TXT record MUST be placed under the `default._bimi` selector of your domain to be correctly recognized by email providers.
- Strict DMARC Policy: A DMARC policy of `p=quarantine` or `p=reject` is a firm requirement for BIMI. `sp=none;` is not sufficient. This policy is crucial for protecting against spoofing and phishing.
- SVG Logo Specifications: The SVG logo must be a vector graphic, properly scaled, free of embedded links/scripts, served with the correct MIME type (`image/svg+xml`) and accessible via HTTPS.
- VMC Root Domain Inheritance: A VMC applied at the root domain level will be inherited by compliant subdomains, simplifying implementation for organizations with multiple sending domains.
Key considerations
- Cross-Team Collaboration: Successful BIMI implementation requires close cooperation between marketing and IT teams to ensure all technical and brand requirements are met.
- Ongoing Monitoring: Regularly monitor email deliverability metrics (open rates, click-through rates) and use BIMI validators to ensure your implementation remains effective and compliant.
- Testing: Implement thorough testing of BIMI by utilizing free online BIMI validators and sending test emails to different email providers like Gmail and Yahoo. These tools will assist you in identifying any setup problems before a full rollout.
- VMC Selection Factors: When choosing a VMC provider, consider factors beyond just the price tag, such as the ease of the application process, the level of support offered, and their reputation within the email community.
- Prioritize Authentication: Before embarking on BIMI, ensure SPF, DKIM, and DMARC are correctly implemented and actively managed. This is the foundation upon which BIMI is built.
What email marketers say
13 marketer opinions
Implementing BIMI involves setting up SPF, DKIM, and DMARC with a strict policy (p=quarantine or p=reject), creating a compliant SVG logo, obtaining a Verified Mark Certificate (VMC) for Gmail and other providers, and publishing the BIMI DNS record. A VMC at the root domain inherits to subdomains. VMC providers are functionally similar but differ in application and support. BIMI enhances brand recognition and trust, impacting open rates. Testing and monitoring are crucial. Serving the logo with the correct MIME type and HTTPS is important.
Key opinions
- VMC Inheritance: A VMC applied to the root domain will extend its verification to all compliant subdomains, simplifying the process for organizations with multiple sending domains.
- DMARC Requirement: A DMARC policy of p=quarantine or p=reject is mandatory for BIMI to function, ensuring only authenticated emails are delivered and preventing spoofing attacks.
- BIMI Implementation Steps: Key implementation steps include configuring SPF, DKIM, and DMARC; creating a compliant SVG logo; obtaining a VMC (required by Gmail); and publishing the BIMI DNS record.
- VMC Provider Similarity: While the functional outcome of VMC providers is the same, the application process, implementation assistance, and support can vary, influencing the overall user experience.
- Logo Display and Verification: VMCs provide logo display and verification at Google, Apple, Onet (Poland), and Zone (Estonia) domains
Key considerations
- VMC Provider Choice: Consider factors such as price, ease of application, and customer support when selecting a VMC provider, as the experience can vary despite the end result being the same.
- SVG Hosting Requirements: Ensure the SVG logo is served with the correct MIME type (image/svg+xml) and is accessible via HTTPS to comply with security requirements.
- BIMI Testing: Test your BIMI implementation with online validators and by sending test emails to various email providers to identify and resolve any configuration issues before a full rollout.
- BIMI Monitoring: Monitor email deliverability metrics, such as open rates and click-through rates, to assess the impact of BIMI on your email marketing campaigns and identify any areas for improvement.
- BIMI and Brand Recognition: BIMI is a great option to help brand recognition and trust with potential clients and helps ensure recipients that the email is legitimate and from a trusted source.
