To solve this, we built an internal email warmup system for our personal use. After deep research into email deliverability, we created a stronger, more reliable solution.

Other startups in the incubator quickly asked to use it too; so we turned it into a real product.

After launching publicly, Mailwarm became #1 Product of the Day on ProductHunt and was accepted into Y Combinator, the world’s most prestigious startup accelerator.
