What is InboxFlood? InboxFlood exists because testing email deliverability on a brand-new inbox doesn't work. An empty inbox has no history — its filter has nothing real to learn from, so sending a test campaign into it and checking where it lands tells you almost nothing. How it works InboxFlood...

As answered by people managing InboxFlood and GitHub.
InboxFlood's answer
InboxFlood doesn't simulate engagement on a closed network — it subscribes the inbox to hundreds of real newsletters, and treats actual engagement (not just volume) as what trains the filter. That same real-mail approach is also why it works for competitive research and QA testing.
InboxFlood's answer
Most competitors warm up inboxes with simulated traffic on a closed mailbox network. InboxFlood uses real newsletters instead, so the engagement training the filter is genuine, not manufactured — and the same real-mail data doubles as competitive research or QA test data, which single-purpose warmup tools don't offer.
InboxFlood's answer
Three groups, all solving a "real mail" problem: people testing email deliverability before sending real campaigns, marketers tracking what their niche is sending in newsletters, and developers/QA teams who need realistic inbox data to test filters against.
InboxFlood's answer
It started from a recurring frustration in deliverability work: testing a campaign against a brand-new, empty inbox and getting a result that meant nothing, because the inbox had no real history behind it. I built the first version of InboxFlood just to fix that for myself — feed an inbox real newsletters, engage with them, then test against something real. Once it worked, I noticed marketers and developers wanted the same "real mail" data for completely different reasons, and it grew from there.
