Email Marketing That Drives 40%+ Revenue: List Growth, Offers & Retention with Max Sturtevant

Published on: 1st April, 2026

Email is still the highest-ROI growth channel in ecommerce. But most brands overcomplicate it and leave serious money on the table.

In this episode of Ecom Growth Insider, I sit down with Max Sturtevant, founder of Wellcopy, one of the biggest email & SMS agencies in the DTC space. Max’s team supports around 130 brands with a team of roughly 80 people, and he shares the exact retention levers that consistently move revenue.

We break down:

  • Why list growth is the #1 lever in email (and what to track)
  • Pop-up strategy: what conversion rates to aim for and how to improve them
  • Offer testing that actually works, including the “mystery discount” approach
  • The biggest trap in retention: over-segmentation and overcomplication
  • How to “send to engaged” without wrecking deliverability
  • Flows vs campaigns: what to prioritize as you scale
  • What 7–9 figure brands do differently with email

If you run a Shopify store and want higher LTV, more repeat purchases, and more profit without increasing ad spend, this episode is a must-listen.
