Product of the Day14th
Hey everyone, Thought I’d share a bit of context behind why we started building Keplars. While working on a product, I needed to set up transactional emails - and that’s where things started to feel unnecessarily complicated. Most tools required separate effort just to get started - configuration, setup, figuring out how everything works - all before you could actually use it. It felt like I had to pause building the product to deal with email infrastructure. So I built something simple for myself. In one night, I put together a basic working setup - just a single page, everything left-aligned, nothing fancy, but emails were being sent. But once it worked, I got really drawn into it. I kept refining it, improving reliability, simplifying the workflow, and adding visibility into what actually happens after sending an email. Over time, that small solution evolved into Keplars. The idea has stayed the same - reduce friction, make email easy to start with, and make it feel like a natural part of the product, not a separate system.
