Community Voice & Feedback
email infra tools always end up more complex than expected. is this dev heavy or usable for non-tech teams also
This hits home.
I’ve used SendGrid in the past, and honestly, the biggest friction wasn’t just setup, it was everything after.
Deliverability felt like a black box, and when things went wrong, support wasn’t always helpful or timely. You end up spending more time debugging email than actually building your product.
What stands out about Keplars from this story is the focus on:
- reducing setup friction
- making email feel like part of the product (not separate infra)
- and actually giving visibility into what happens after sending
That last part is huge, because sending is not aka delivery
Congrats for the launch!

Congrats on the launch @debojyoti452 love the product. Early adopter and have manged to use it as my go to email as a service solution for FoundersBoxx and other projects. Love the new features.
positioning email infrastructure as a product team problem rather than a backend one is the interesting move here. delivery visibility and sandbox testing are usually buried behind DevOps access, so making them something the product team can reach directly removes the whole "can someone check if that onboarding email actually fired" loop, which anyone who's shipped a transactional flow knows is more annoying than it sounds :)
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.
