BIMI implementation requires a DMARC policy set to quarantine or reject, valid SPF and DKIM records, and a Verified Mark Certificate (VMC) for your logo, especially for providers like Google. The VMC validates logo ownership and requires trademarking. DMARC reports are crucial for identifying and troubleshooting authentication failures. Common errors include incorrect DNS syntax, unvalidated VMCs, and overly permissive DMARC policies. While BIMI itself might not directly boost deliverability, it enhances brand recognition, engagement, and sender reputation. Monitor DMARC compliance and utilize online BIMI checkers. SPF records have lookup limits, and one-off authentication failures can occur. Setting up SPF/DKIM for all mailstreams and tweaking settings for senders like HubSpot are important.
