Mailwarm's answer:
Mailwarm started as a real problem we faced ourselves.
We were two founders working at Station F in Paris, the largest startup incubator in Europe, trying to sell our own products. Every time we launched outreach campaigns, our emails kept landing in spam.
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 worldโs most prestigious startup accelerator.
Since then, Mailwarm has grown into a trusted platform used by thousands of companies to improve inbox placement and email deliverability.

At the beginning, I wasnโt fully sure what to expect, but the onboarding process was simple enough to get me started quickly.
