Small service business loses over half of its outgoing emails to spam folders, causing missed appointments and lost revenue, with no way to detect the problem.

Workarounds Described

• Manually tested by sending to personal Gmail/Outlook accounts
• Had customer check spam folder for past emails
• Cleaned email list by removing non-engagers manually
• Set up separate sending addresses for confirmations vs. marketing
• Moved marketing emails to dedicated sending infrastructure (PuzzleInbox, Mailforge, Maildoso)

Implied Software Gaps

• Automatic inbox placement testing and alerting without manual effort
• Guided SPF/DKIM/DMARC setup that warns if incomplete
• Automatic identification and removal of dead addresses from email list to improve sender reputation
• Segmented sending lanes for transactional vs. marketing emails to prevent spam filtering of important messages
