How I Built an AI Email Platform as a Solo Founder (Cresca Behind the Scenes)

Like many founders, I was frustrated by how long it took to write, design, and send emails.
So I built Cresca — a tool that lets you do all of that in seconds using AI.

Here’s how I went from idea → product → live launch in just a few months.

1. The Problem Even with modern tools, sending email campaigns felt broken:

Too manual

Too time-consuming

Not built for solo makers or small teams

I wanted to fix that.

1. The Stack Frontend: Next.js, Tailwind, Framer Motion

Backend: Node.js, MongoDB, BullMQ for queues

AI Layer: OpenAI + prompt engineering

Infra: AWS + Upstash Redis

1. Features I Prioritized Email generation via prompt

Campaign scheduling + analytics

Lightweight UI — fast and clean

Instant test sends

1. Lessons Learned Launch early, improve fast

Talk to users, not just code

Simplicity beats feature bloat

Feedback is gold — Reddit, Twitter, IndieHackers helped shape v1
