The Lifecycle Lab · 1 of 1 on the internet

See what your lifecycle email setup actually looks like — before you hire anyone.

I built this lab because every founder asks the same thing: "what flows do I actually need?" Now you can see them. Pick your industry, explore the exact automations I'd build for you, and design the email itself — live, in your browser.

Act 1The flows

Every industry has a different lifecycle shape.

A supplements brand lives or dies by replenishment. A SaaS lives by activation. A jeweler by repurchase windows that span years. Pick your industry — see the exact flows I'd build, with the business reason behind each one.

Industry
Core specialty

Supplements & Nutraceuticals

Supplements are bought for an outcome — sleep, energy, gut, immunity — not for a product. Email's job is to route the right SKU to the right goal, then defend the replenishment window so the customer never runs out. Compliance and claim language live in every send.

Replenishment cadence is the #1 LTV lever — a single missed reorder window can cut customer value by 40%.

Act 2The emailLive

Now design the email itself.

Drag image, text, CTA, coupon, dynamic product grid and HTML blocks onto a real canvas. Switch industries to load battle-tested templates. This isn't a screenshot — it's the same kind of editor I use every day.

Desktop-only experience

The live designer needs a bigger canvas.

Open this page on a laptop or desktop to drag image, text, CTA and coupon blocks onto a real email canvas. On mobile, you can still explore the flows above.

Why I built this

Most lifecycle work is invisible. This makes it tangible.

In 3.5 years and 180+ flows, the same pattern repeats: founders sign with an agency, wait 6 weeks, then squint at a Klaviyo dashboard hoping it's working. I built the Lab so the conversation starts with "here is exactly what your setup will look like" — not a slide deck of promises.

Every flow you see in the explorer is one I've shipped. Every block in the designer maps to a real email pattern that earned its place by moving revenue. Nothing here is theoretical.

"Uday doesn't just build flows — he explains the why behind every send. We doubled email revenue in one quarter."

"The industry-specific approach is rare. Most agencies template you. Uday actually re-mapped our lifecycle."

"Replenishment cadence alone added 18% to LTV. Worth ten of his fee."
