InboxFlood: subscribes your inbox to hundreds of newsletters

InboxFlood automatically subscribes your inbox to hundreds of curated newsletters. Perfect for competitive research, email filter training, and developer testing.

I built InboxFlood after spending countless hours manually subscribing test inboxes to newsletters while troubleshooting email deliverability. The process was repetitive, slow, and made it difficult to create realistic inbox environments for testing. The idea evolved from a simple automation tool into a platform focused on helping email professionals verify inbox ownership, build representative test inboxes, and evaluate how their emails perform under real-world conditions. Throughout development, I refined the workflow to make it fast, reliable, and easy to use while emphasizing responsible use and user verification. My goal was to eliminate hours of manual work and give marketers, deliverability specialists, and developers a practical way to test and improve their email campaigns with greater confidence.

Honestly curious about the real-world use case here - flooding your own inbox seems counter to what most people want, but I get the angle for filter training. Watched it run briefly and was surprised how fast it pulled in actual newsletter content, almost too fast.
