InboxFlood
Automate curated newsletter subscriptions
What this is
Feeds a fresh inbox with real newsletter volume and engagement signals, for developers and marketers who need to warm up deliverability before running an actual email campaign.
Our one-line summary — not the founder’s tagline.
- How it works
- Feeds a target inbox hundreds of real, independently-run newsletters daily to build genuine mail volume, then simulates opening, reading, and interacting with that mail to train the inbox's spam filter before a real campaign is sent in to see where it lands.
- Best for
- Cold email senders, agencies, and marketers who need to warm up a fresh inbox's deliverability before scaling a real campaign.

Dev. Launched 9d ago on PeerPush, where it placed #542. Today, it's live, but nothing on the site has changed since we started watching.
Quiet for 6 days — no penalty yet, but quiet doesn't stay free.
We check this site every day, ourselves. A founder can post “still working on it” — a claim like that doesn't price. What we price is what we can verify from the outside: evidence, not announcements. The real question isn't “will this be huge?” — it's “will they still be moving in four weeks?”
The market viewHow this launch is priced and ranked in our league — the investor side of the page.
ranked by the reality anchor, not the market price
It placed #542 on PeerPush with 10 votes. It also showed up on 1 other board — but didn't place well enough on any of them, so none of them add to the price. Listing on twelve directories is free; placing well on them isn't.
No matter how much money goes in. There is no pump here — you can't make yourself right by buying more. The line only moves on things that actually happened: an award, revenue that grew, a new platform, code that shipped — or silence.
A launch that goes quiet eases down a little at a time — never a cliff you could have run from the night before.
How the launch is moving on its own board, day by day — the crowd's attention.
A flat line is normal: votes stop within a day or two of launch, on every board. What's unusual — and what actually counts — is a launch that keeps pulling votes long after its day is over.
About
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 feeds an inbox hundreds of real, independently-run newsletters every day. That builds genuine mail volume — but volume alone isn't the training signal. The next step is engagement: opening, reading, and interacting with that mail the way a real person would. That engagement is what actually trains the filter. Once the filter has learned from real volume and real engagement, you finally have an inbox worth testing against — send your own campaign in and see, with real confidence, where it lands. Who it's for Cold email senders & agencies testing deliverability before scaling a real campaign Marketers who want to see what their entire niche is sending in newsletters, not just track one rival Developers & QA teams who need realistic inbox data to test how their systems handle real-world mail What makes it different Most tools in this space warm up inboxes by simulating engagement across a closed network of mailboxes sending each other fake conversations. InboxFlood doesn't simulate anything — every newsletter is real and independently run, and the engagement comes from an actual person, not a script. That's also why the same data works for competitive research and QA testing: in all three cases, what matters is that the mail is genuinely real.
Where it launched
2 platformsThe board it did best on sets the price. Every other board only adds to it if the launch also placed high on that board too — because just showing up somewhere isn't an achievement. Listing on twelve directories is free; placing well on them isn't.
