RetailEmail Deliverability4HighOwner$ implied

Promotional emails to regular customers are landing in spam since December, causing open rates to drop by over half, and the business owner cannot determine whether the issue is technical (Google's new bulk sender requirements) or tool-related.

Existing email tools don't provide clear deliverability diagnostics or compliance guidance for new sender requirements (like Google's bulk sender policies), leaving small business owners unable to diagnose and fix spam filtering issues without technical expertise.
