Elastic Email

I'm going to say something that will irritate about 99% of ecommerce email agencies on X: Most of them don't actually do email marketing strategy. They do flow installation. Every ecommerce founder has heard the same checklist repeated endlessly: "Make sure you have the core flows set up." • Welcome flow • Abandoned checkout • Abandoned cart • Browse abandon • Post purchase • Winback So agencies install them. They know the names of the flows. They know how to connect Klaviyo. They know how to design a decent-looking template. And then they call it retention marketing. This is the equivalent of knowing the names of gym machines and calling yourself a strength coach. Because the real question is not which flows exist. The real question is: • What exactly happens inside them? • What psychological triggers are used? • What objections are neutralized? • What buying behavior are we trying to create? • What stage of the customer lifecycle is being moved forward? 99% of agencies have absolutely no answer to this. They install a welcome flow because "every brand needs one." But they cannot explain: • Which emails should push the second purchase • Which emails increase average order value • Which emails accelerate repurchase velocity • Which emails build long-term LTV Because they've never actually tested for those outcomes. And this is the dirty secret of the email marketing industry. Most agencies have never run real lifecycle experiments. They've never isolated variables. They've never tested strategic messaging against behavioral outcomes. They've never built an experiment where the goal was explicitly: "Increase repurchase rate." Instead they optimize for vanity metrics. Open rates. Click rates. Campaign revenue screenshots. None of which actually determine whether a brand scales. What determines whether an ecommerce brand becomes durable is two things: • Repurchase rate. • And customer lifetime value. Everything else is noise. When you design email systems around those two metrics, the entire architecture changes. Because now you're not asking: "Did this email get clicks?" You're asking: "Did this email change customer behavior?" "Did more people buy again?" "Did they buy sooner?" "Did they spend more over time?" That's the only thing that matters. And when you actually run experiments around this, the results get very uncomfortable for agencies who only install flows. Because strategic lifecycle emails move numbers in ways templates never will. For example. We ran a experiment for one brand where we tested a behavior-driven repurchase sequence against the typical non-pushy nurture emails most agencies write. Same audience. Same products. Only the strategy of the emails changed. The result: Repurchase rate increased by 40%. Customer lifetime value increased by 18.6%. Different brand. Different niche. We ran a similar experiment focused specifically on repurchase acceleration inside the post-purchase flow. Again, same emails. Only the strategic framing of the emails changed. Result: Repurchase rate increased by 34.9%. Customer lifetime value increased by 13.72%. No fancy designs. No aggressive discounting. No hack. Just strategic lifecycle messaging engineered to move customers toward the second and third purchase faster. Which is where most ecommerce profit actually lives. But you almost never see agencies talk about these kinds of tests. Because running them requires something most retention teams don't have: A strategic hypothesis. You need to understand why customers hesitate to repurchase. Where trust breaks down after the first order. What psychological triggers move someone from buyer → repeat buyer → loyal customer. And then you need to design emails specifically to solve those problems. That's strategy. Not installing flows. The funniest part is that most ecommerce founders assume email agencies already do this. They assume someone somewhere is optimizing the lifecycle. In reality most retention programs look like this: • Install flows • Send campaigns • Report revenue • Repeat every month. Meanwhile the brands quietly dominating ecommerce are doing something completely different. They treat email like a behavior engineering system. Every sequence has a specific objective: • Increase second purchase probability. • Increase basket size. • Reduce time between orders. • Extend lifetime value. When email is built around those outcomes... the revenue increase shows up everywhere. Ads become more profitable because higher LTV means higher allowable CAC. Word of mouth increases because loyal customers actually recommend brands. And the business stops depending entirely on paid traffic to survive. Email stops being a channel. It becomes the economic engine of the brand. But that only happens when someone is actually doing strategy. And strategy requires one thing most agencies have never done. Run real tests that change customer behavior. Start doing that or find someone who already does.

Honestly, is there any alternative to postman ?
