How Aztek Boosted Email Open Rates by 71% with a Smarter Deliverability Strategy

When Bil-Jac, a premium dog food brand, began seeing declining email engagement, they turned to Aztek to solve critical deliverability challenges and reinvigorate their Best Friends Club (BFC) newsletter strategy. Through detailed analysis and a thoughtful, multi-layered approach, we restored inbox placement, enhanced their email metrics across the board, and strengthened their coupon-driven automation program.

Pain Points:

Declining Engagement Metrics:

Open and click rates were consistently low, falling well below benchmarks. 

Unengaged Email List:

A large, unsegmented list of inactive subscribers caused deliverability issues, diluted engagement, and made it difficult to gauge true performance.

Inbox Placement and Deliverability Issues:

A poor domain reputation resulted in emails landing in spam folders, especially in Gmail – their most-used email client – severely limiting reach and engagement. 

Strategy & Execution

Aztek implemented multiple strategies to improve deliverability and address engagement issues. 

Engagement-Based Segmentation

  • Aggressively segmented the email list by subscriber activity (e.g., 0–30 days, 30–60 days, etc.). 
  • Focused campaigns on engaged subscribers (180-day engagement window) to improve sender reputation. 
  • Gradually reintroduced unengaged subscribers through annual re-engagement campaigns, adding over 14,000 subscribers back into the active list. 

Deliverability Infrastructure Optimization

  • Audited and corrected DNS records, SPF, DKIM, and DMARC settings to authenticate emails properly and improve trust with inbox providers. 
  • Connected the domain to Google Postmasters to monitor and address Gmail-specific issues, improving domain reputation from "poor" to "high." 
  • Conducted regular inbox placement tests using Litmus to confirm emails moved out of spam folders into recipients' primary inboxes. 

Automation and Content Strategy Adjustments

  • Redesigned the BFC automation sequence to better target unengaged users: 
  • Added a resend email targeting subscribers who hadn’t opened the final email in the sequence, leading to hundreds of additional coupon requests. 
  • Optimized subject lines, preview text, and send times using ActiveCampaign’s predictive sending. 
  • Enhanced CTA visibility with design updates (larger buttons and more engaging copy). 

List Hygiene Practices

  • Removed over 20,000 inactive subscribers who failed to re-engage, reducing list bloat and improving deliverability. 
  • Conducted annual re-engagement campaigns to attempt to bring lapsed subscribers back into the engaged segment. 
  • Maintained a steady active list size of around 42,000 engaged subscribers.
