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 GitHub and InboxFlood.
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.
