Most temp mail services give you 10 minutes. That's often not enough when the OTP takes 15. Inboxflip gives you 24 hours: → No signup or registration → Real-time inbox — OTPs appear instantly → Auto-deletes everything after 24h → No tracking pixels or ad cookies by default → Receive-only (no send = no abuse) Built for throwaway signups, OTP verification, developer testing, and keeping your real inbox spam-free.

Hey Product Hunt 👋

I built Inboxflip because I kept running into the same problem with disposable email tools: by the time a verification email arrived, the 10-minute inbox had already expired.

So Inboxflip works a little differently:

→ 24-hour inbox instead of 10 minutes — survives delayed OTPs

→ Zero signup — address generated the moment you open the page

→ No tracking pixels or ad cookies loaded unless you opt in

→ Receive-only by design — no send capability means no abuse vector

It's completely free, no premium tier, no catch.

Would love your feedback — especially if you run into a site that blocks the domain, or have ideas for what would make this more useful for your workflow.
