Temp Mail vs Guerrilla Mail vs Yopmail: Which Wins?
Temp Mail, Guerrilla Mail, and Yopmail are three of the most well-known disposable email services. They all give you a throwaway inbox without requiring an account. But they approach the problem differently enough that the "best" one depends entirely on what you need.
Here's how they compare head-to-head, and when a different service beats all three.
The Three Services
Yopmail
Yopmail has been running since 2004 — the longest of the three. You type any username at @yopmail.com and the inbox exists. No randomization, no session — you choose the address and can return to it anytime (and so can anyone else). Emails are retained for about 8 days. It's receive-only with fully public inboxes. The interface is functional but dated.
Strengths: Choose your own address, return to it later, longest track record. Weaknesses: Receive-only, fully public, widely blocklisted, dated UI.
Temp Mail (temp-mail.org)
Temp Mail generates a random address automatically when you visit the site. The inbox persists for your browser session and disappears when you leave. The interface is clean and mobile-friendly — noticeably better than Yopmail and Guerrilla Mail on phones. It's receive-only with no privacy beyond session isolation.
Strengths: Clean mobile UX, automatic random address, no decisions required. Weaknesses: Receive-only, session-based (close the tab and it's gone), no persistence, blocklisted.
Guerrilla Mail (guerrillamail.com)
Guerrilla Mail has been operating since 2006. Its defining feature is limited sending capability — you can compose and send emails, not just receive them. Inboxes are instant and free. Like the others, inboxes are fully public with no privacy. The interface is cluttered but functional.
Strengths: Can send emails, no signup, long track record. Weaknesses: Fully public, cluttered interface, limited sending reliability, frequently blocklisted.
Head-to-Head Matchups
Yopmail vs Temp Mail
Both are receive-only and fully public. The key difference is the experience model. Yopmail lets you choose your address and return to it across sessions — useful if you want to reuse the same throwaway address. Temp Mail assigns a random address and ties it to your session — simpler if you just need something quick and don't care about the address.
Temp Mail wins on mobile UX by a wide margin. Yopmail wins on persistence (8 days vs session) and address control. Both are widely blocklisted, though the specific domains that get blocked vary.
Pick Yopmail if you want to choose your address or come back later. Pick Temp Mail if you're on your phone and want the fastest path to an inbox.
Yopmail vs Guerrilla Mail
The main difference: Guerrilla Mail can send, Yopmail cannot. Both have fully public inboxes and both have been around for a long time. Yopmail's interface is cleaner; Guerrilla Mail's is more cluttered but more capable.
Pick Yopmail if you only need to receive. Pick Guerrilla Mail if you need to send a quick email from a throwaway address.
Temp Mail vs Guerrilla Mail
Temp Mail offers a cleaner, more mobile-friendly experience. Guerrilla Mail offers sending capability. Both are public with no privacy. Temp Mail is session-based; Guerrilla Mail offers slightly more persistence.
Pick Temp Mail for a clean receive-only experience on mobile. Pick Guerrilla Mail if you need to send. For a detailed look at Guerrilla Mail alternatives, see our Guerrilla Mail alternatives comparison.
The Winner Depends on Your Use Case
| Use case | Winner |
|---|---|
| Quick verification on mobile | Temp Mail |
| Choose your own address | Yopmail |
| Come back to inbox later | Yopmail |
| Need to send an email | Guerrilla Mail |
| Cleanest interface | Temp Mail |
| Longest retention | Yopmail (~8 days) |
None of these three services offer privacy, custom domains, long-term retention, or full email sending with IMAP/SMTP.
The Alternative That Beats All Three
Reusable.Email covers the strengths of all three services and adds capabilities none of them offer.
| Feature | Yopmail | Temp Mail | Guerrilla Mail | Reusable.Email |
|---|---|---|---|---|
| Choose your address | Yes | No (random) | No (random) | Yes |
| Sending | No | No | Limited | Full SMTP (managed) |
| Privacy | Public | Session | Public | Public / private / managed |
| Retention | ~8 days | Session | Limited | 90d / 180d / 365d |
| Custom domain | No | No | No | Yes ($10/year) |
| IMAP/SMTP | No | No | No | Yes (managed, $3) |
| Mobile UX | Dated | Good | Poor | Good |
| Cost | Free | Free | Free | Free / free / $3 one-time |
| Blocklist risk | Very high | High | High | Lower |
Reusable.Email's public inbox does what Yopmail does — choose an address, use it instantly — but with 90-day retention and lower blocklist exposure. For deeper detail on Yopmail's trade-offs, see our Yopmail alternatives guide.
Reusable.Email's private inbox (free) adds what none of the three offer: password-protected inboxes with 180-day retention.
Reusable.Email's managed inbox ($3 one-time) replaces Guerrilla Mail's limited sending with full SMTP/IMAP — a real email account you can connect to any client.
Bottom Line
Yopmail, Temp Mail, and Guerrilla Mail all do their specific jobs. If one of them works for what you need, there's no reason to switch. Yopmail for reusable throwaway addresses, Temp Mail for quick mobile use, Guerrilla Mail for basic sending.
When you need more — privacy, real sending, persistence, acceptance on sites that block the Big Three — Reusable.Email fills the gaps.
