Across the brands we operate, owned channels (email and SMS) consistently account for 25% to 35% of total revenue. Not 5%. Not 10%. A third of the P&L, on a cost line that's a rounding error compared to paid media. And yet most stores are running three flows and a monthly newsletter.
This isn't about volume. It's about the fact that the cheapest customer to convert is the one who already trusted you enough to give you their email. Every dollar you don't spend re-acquiring that person is a dollar of margin.
The three flows you cannot skip.
If you build nothing else this quarter, build these. In our portfolio, they collectively account for 60-70% of all flow revenue.
- Welcome series (5-7 emails). This is the highest intent moment in the relationship. Don't waste it on brand story. Email one is the discount. Email two is social proof. Email three is the founder story. Email four is the bestsellers. Email five is the soft close. Half your list will convert in this sequence or never.
- Browse and cart abandonment (3 emails each). The two together typically print 15-20% of total email revenue. Send the first within an hour, the second the next morning, the third 48 hours later with a small incentive. Don't discount on email one, you'll train your list to wait.
- Post-purchase (4-6 emails over 30 days). The most under-built flow in ecommerce. Order confirmation, shipping notifications, delivery follow-up, review request, cross-sell, replenishment. This is where you turn one-time buyers into repeat customers, and where LTV gets made.
Two campaigns to ship this week.
Flows are the foundation. Campaigns are the headline. Two ideas that work in almost every category:
- The bestseller restock. Pick your top SKU. Email the whole list. Subject line: the product name. Body: one line, one image, one button. No clever copy. We've seen this single format outperform thoroughly designed campaigns 4 out of 5 sends.
- The behind-the-scenes. A photo or video from your warehouse, your kitchen, your studio. Two sentences from the founder. No CTA other than "reply if you have a question." This is your highest open-rate, highest reply, highest goodwill email of the quarter. The revenue is indirect but the relationship compounds.
The segments that print money.
Most brands send every campaign to their entire list. That's the fastest way to burn deliverability and train inbox providers to filter you straight into Promotions. Better: send the right message to the right slice. Four segments worth the setup:
- VIP (top 10% by LTV). They get early access, private discount codes, and the founder's direct reply address. Conversion rate runs 3-5x the list average.
- 30-day engaged non-buyers. Opened or clicked in the last 30 days, never purchased. The cheapest cohort to convert. Hit them with a tighter offer than the welcome series.
- 60-90 day repeat candidates. Bought once, window for second purchase is closing. Replenishment reminder or category cross-sell, with a low-friction incentive.
- 120+ day dormant. Win-back series. Three emails. If they don't engage, sunset them out of your active list. Holding dead weight tanks deliverability for everyone else.
What stops most brands.
It isn't lack of tools. Klaviyo will do all of the above out of the box. It isn't lack of templates either, there are thousands online. What stops most brands is treating email like a side project for an overstretched marketing coordinator, instead of a revenue channel that deserves the same operator-level attention as paid media.
If paid is 50% of your revenue, you'd never let it run without a dedicated owner, a weekly cadence, and a number to hit. Email deserves the same. The brands that treat it that way win the retention math, and retention is the only math that matters once CAC stops being free.
