Description

Warpify.co was a SaaS that helped sales teams bypass the traditional email warming process and start outreach campaigns immediately.

We discovered a bug in Microsoft Outlook that allowed us to avoid email limits and blacklisting, reducing warmup time from weeks to just 24 hours.

The platform gained traction quickly, but Microsoft eventually patched the exploit we were using, teaching us valuable lessons about building on external dependencies.
