Got tired of disposable emails being blocked, so I built my own

Hey folks,

If you are someone who keeps testing tools like Replit, Lovable, Cursor, or random SaaS trials, you have probably felt this pain already: disposable emails are basically useless now.

Most public temp mail services are heavily blacklisted. Half the time verification emails never arrive, and the other half your account gets flagged instantly. It was getting annoying enough that I decided to just fix it myself.

So I built Open-Temp-Mail.

The idea is simple. Instead of using public disposable email domains, you buy any cheap domain, hook it up to Cloudflare, and run your own temp mail system on it.

What you get:

• Unlimited email addresses on your own domain
• Working signups and verification emails
• No shared blacklisted domains
• Separate inboxes for testing, trials, and experiments
• Runs completely serverless on Cloudflare and costs basically nothing

Since the domain is yours and not shared with thousands of people doing sketchy stuff, it behaves like a normal email domain. In practice, it works way better than public temp mail services.

Tech stack, if you care:

• React + Vite
• Tailwind CSS v4
• Cloudflare Workers
• Cloudflare D1
• TypeScript

Everything runs at the edge, inbox updates are near real time, and setup takes only a few minutes once the domain is connected.

This is not about abusing platforms. It is just about owning your setup and removing friction when you are building or experimenting a lot.

The project is open source and still evolving. If you have ideas for features, UX tweaks, or security improvements, I am very open to feedback.

Hope this helps someone who is also tired of disposable email pain.
