  • Limited Customization
    Some users may find that Mailwarm’s automation features lack the level of customization required for highly specific or complex email strategies.

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.
