The crisis.

A wellness research institute sending 10 million emails monthly was experiencing catastrophic deliverability decline. Their therapy course sales, heavily dependent on email marketing, were suffering from plummeting open rates:

  • 01 Yahoo/AOL deliverability crisis with 60% spam placement.
  • 02 Shared IP pool issues with 4 IPs on blocklists.
  • 03 16,000+ emails failing SPF evaluation.
  • 04 Maximum spam scores (SCL 5) for Outlook/Hotmail.
  • 05 Year-over-year performance down 10%.

The recovery.

  • MONITORING
    Upgraded to GlockApps Enterprise ($200/mo) for professional monitoring.
  • POSTMASTER
    Configured Google Postmaster Tools and automated DMARC reporting.
  • IP REPUTATION
    Identified and resolved shared IP reputation issues.
  • DNS
    Optimized DNS records including DMARC policy enhancements (fo=1).
  • STRATEGY
    Implemented provider-specific campaign strategies.
  • CONTENT
    Developed content strategy changes to reduce promotional density.
  • INFRASTRUCTURE
    Transitioned to dedicated IP strategy with proper warmup.

The hardest part.

The biggest hurdle wasn’t technical — it was changing decades-old email practices. I had to convince the team to adopt modern deliverability standards while maintaining their direct-response approach that drove course sales.

// OUTCOME

What shipped, in numbers.

  • 01 Yahoo open rates recovered from 2% to 33%.
  • 02 Spam placement reduced from 60% to 23%.
  • 03 99%+ DMARC compliance across 10M monthly emails.
  • 04 Dedicated IP strategy and Postmaster monitoring running in production.
