Description
MailOnce is a private temporary email service for fast signups, OTP codes and email verification without exposing your real inbox. Each inbox is private to your browser session instead of publicly accessible. Create random or custom temporary addresses, receive emails in real time, detect OTP codes and verification links, and manage everything from your browser. No account is required for basic use. Built for everyday privacy and developer testing.

Could you build this?
Yes Temporary email services can be quickly assembled using an inbound mail webhook provider (like Cloudflare Email Workers, Mailgun, or AWS SES) and a standard realtime frontend (Supabase/Firebase).
