What is a disposable email generator?

A disposable email generator creates a temporary inbox in seconds — no signup, no personal info, no tracking. You use it for one purpose (verifying a signup, downloading something gated, getting a one-time discount code), then walk away. The inbox auto-expires.

Why this matters: every site you sign up to with your real email is a potential leak. They store it. Some sell it. Many get breached. A disposable email is the simplest way to keep your real inbox clean and your identity de-correlated from the dozens of services you'll only ever use once.

TempMailPro is a developer-first disposable email service. We built it because Mailinator costs $79/month and most free services are slow, ad-heavy, or unreliable. Our free tier is fast, clean, and supports real-time delivery via WebSocket.

Why TempMailPro vs other generators

Real-time email delivery

Most generators make you refresh manually. We push new mail to your browser instantly via WebSocket.

24-hour retention (free tier)

Original 10-minute services expire too fast — you miss codes that arrive late. We give you 24 hours by default.

No ads on the free tier (yet)

Cleaner UI, faster page load, less visual noise. We monetise via the developer API, not pop-ups.

Developer REST API

Most generators don't have one. We do — for QA testers, signup-flow automation, fraud teams. Cheaper than Mailinator.

HTML email rendering

Some services strip formatting. We render HTML safely (DOMPurified) so you see emails like in Gmail.

Attachment support

PDFs, images, ZIPs — up to 2 MB free, more on paid plans. Most generators block all attachments.

FAQ

Is it really free?
Yes. The web inbox (1 active inbox, 24-hour retention, real-time delivery) is free forever. Paid plans unlock the API, custom domains, longer retention, and more inboxes.
Can I use this for development?
Yes — that's exactly who we built it for. The disposable inbox is also accessible via REST API on paid plans, so you can automate signup-flow tests in CI.
Do you store my data?
Inboxes are auto-deleted after 24 hours (free tier). We never sell or share data. Source: read our privacy policy.
Why don't you let me send email?
Receive-only by design. If we let users send, the service would be abused for spam within hours, and our SMTP reputation would tank — meaning legitimate verification emails would stop arriving for everyone. Receive-only keeps the service reliable.
What if I want a permanent custom email address?
Paid plans support BYOD (Bring Your Own Domain). You connect a domain you own and create permanent disposable inboxes on it.
