Summary
The consensus across email marketers, experts, and official documentation is that there is no explicitly stated minimum email volume required for BIMI logo display in Gmail. While volume can contribute to building sender reputation, factors such as proper email authentication (SPF, DKIM, DMARC), consistent sending habits, good list hygiene, and achieving a Verified Mark Certificate (VMC) are considered more crucial. Some have successfully implemented BIMI with low-volume sending, while others suggest that maintaining a consistent and substantial email flow aids in building a reliable sender reputation, which is essential for BIMI to function correctly. Low volume may result in a longer period for Google to ascertain sender reputation.
Key findings
- No Explicit Volume Requirement: Neither Gmail nor official documentation explicitly state a minimum email volume for BIMI logo display.
- Sender Reputation is Paramount: A strong sender reputation is consistently highlighted as the most critical factor for BIMI success.
- Authentication and VMC are Essential: Properly configuring SPF, DKIM, and DMARC records, as well as obtaining a Verified Mark Certificate (VMC), are crucial prerequisites for BIMI implementation.
- Low Volume BIMI is Possible: Several marketers have successfully implemented BIMI with low email volumes, demonstrating that it's achievable with the right setup and practices.
- Consistency Over Quantity: Consistent sending habits, good list hygiene, and engagement are valued more than simply sending a large volume of emails.
Key considerations
- Implement Robust Authentication: Ensure your sending domain is properly authenticated with SPF, DKIM, and DMARC records.
- Obtain a VMC: Secure a Verified Mark Certificate (VMC) from an authorized Certification Authority.
- Maintain Consistent Sending Practices: Establish a regular and predictable sending schedule to build trust with mailbox providers.
- Practice Good List Hygiene: Regularly clean your email lists to remove inactive or invalid addresses to minimize bounces and spam complaints.
- Monitor Sender Reputation: Use tools like Google Postmaster Tools to monitor your sender reputation and identify any potential issues.
