Email and SMS are the highest-ROI channels in ecommerce because you own them — no algorithm tax, no rising CPMs, and you’re marketing to people who already bought or opted in. Here’s the complete system for repeat revenue.
Grow the list
Every visitor and order is a chance to capture an email/phone: signup incentives, checkout opt-ins, popups that don’t annoy. Your list is an owned asset that compounds.
Flows do the heavy lifting
Automated flows drive most email revenue — welcome, abandoned checkout, browse abandonment, post-purchase, win-back. If you run one thing well, run these. See the flows that make money.
Campaigns keep you top-of-mind
Broadcast sends (launches, promos, content) drive spikes and reinforce brand. Lead with value, not just discounts, and keep a sustainable cadence.
Segment for relevance
Blasting everyone the same message wastes your list. Segment by behavior, purchase history and engagement — relevance drives revenue and protects deliverability.
Add SMS strategically
SMS for time-sensitive moments — abandoned checkout, launches, back-in-stock. High open rates, low frequency tolerance.
Measure what matters
Revenue per recipient, flow revenue, and list growth — not opens alone. This is core to how we run retention.

Every visitor and order is a capture opportunity: signup incentives, checkout opt-ins, and non-annoying popups. Your list is an owned asset with no algorithm tax — unlike paid, it doesn’t get more expensive over time. Growing it is compounding leverage.
Flows vs campaigns
Automated flows (welcome, abandoned checkout, post-purchase, win-back) drive most revenue while you sleep — build these first. Broadcast campaigns (launches, promos, content) keep you top-of-mind and drive spikes. You need both, but flows are the foundation.
Deliverability protects everything
Blasting your whole list the same message hurts deliverability and revenue. Segment by behavior and engagement, sunset dead contacts, and lead with value. Landing in the inbox is a prerequisite for every other email tactic working.
The metrics that actually matter
- Contribution margin per order (not just revenue)
- CAC and payback period
- LTV:CAC ratio (aim for 3:1 or better)
- Repeat purchase rate
- Blended MER across all channels
Where most brands leave money
The biggest wins are rarely in acquisition — they’re in conversion and retention. Doubling your repeat rate or lifting conversion by a point often beats spending more on ads. Audit your funnel end to end: traffic in, conversion, average order value, and repeat rate. Fix the weakest link before scaling spend on the others.
