CoolMail vs Temp-Mail: which temporary email should you use?
Temp-Mail.org popularized disposable email and is the category's reference point. This comparison is honest: it's great for pasting a quick email and vanishing. Where CoolMail wins is when the inbox needs to actually work — verification codes, privacy, automation.
Side by side
| Criterion | CoolMail | Temp-Mail.org |
|---|---|---|
| Inbox privacy | Unique address: only your browser reads it | Public inbox: whoever types the address reads everything |
| Expiry | Free: 24h · Permanent: never expires | Inbox lives minutes; refreshing may swap your address |
| Verification code | Detected and highlighted, 1-click copy | You hunt for it in the HTML/email by hand |
| Domains | Own rotating pool (permanent tier off disposable lists) | Well-known domains, frequently blocked at sign-up |
| API for automation | Yes: create inbox and long-poll the code (25s) with public docs | No open public API; automation becomes scraping hacks |
| Price | Free without an account · R$ 5 (~US$1) one-time for permanent | Free with ads; paid apps and upgrades by subscription |
| Payment | Pix (R$ 5, one time) | International card, subscription |
| Ads | None | Banners and interstitials in the inbox |
When each one makes sense
CoolMail shines when…
- The sign-up matters: you'll receive a code and maybe return to the account later
- You want a private inbox — you don't want strangers reading your messages
- It's automation: the API hands you the code via long-poll
- The inbox becomes permanent: pay R$ 5 once and it's yours forever, with API and history
Temp-Mail works when…
- It's a 2-minute throwaway nobody will ever touch again
- You don't want an account or a code — just check that it arrived
- The site doesn't block its domains
Verdict
For an anonymous 2-minute throwaway, both work — and Temp-Mail has done that job for years. The turn comes when the inbox needs to actually work: code verification you don't hunt in HTML, an inbox that doesn't expire mid-sign-up, and API automation. That's where CoolMail delivers what Temp-Mail doesn't attempt: a private inbox, permanent if you want (R$ 5, one time), and the code ready to copy. Start free: the free inbox opens on the homepage with zero sign-up.
