Disposable email: the honest comparison
YOPmail, Temp-Mail, Guerrilla Mail… which one to choose in 2026? We compare without bias: blacklists, retention time, ads, privacy and ease of use.
Why compare these services?
YOPmail is the pioneer, active since 2004. But its domain is now on most blacklists: Amazon, PayPal and many SaaS systematically block it. Temp-Mail is the most visited (46 million visits/month) but displays aggressive advertising. mail123.fr is hosted in France, with few ads, push notifications on your inbox and 13 domains (if one domain is refused, another works), notably accepted by AI services.
This comparison objectively rates 13 criteria. Some criteria favour our competitors, intentionally: a biased comparison helps no one.
Quick, no-signup access: mail123.fr. Need an API or to send emails: Guerrilla Mail. Full privacy without a public inbox: addy.io / SimpleLogin.

Methodology & screenshots
The ratings above didn't come out of nowhere. Here's how we evaluate each service, what we measured, and what these home pages actually look like, screenshots included, taken in May 2026.
How we rate
Each service is rated on 13 technical criteria (speed, retention, security, design, etc.). The score is a weighted average, not a personal opinion. Criteria that disadvantage mail123, like retention or AI service acceptance, are rated honestly.
When and how
Tests conducted from Marseille (France), on Firefox and Chrome, in private browsing, without ad blocker. Each service was used on 5 real scenarios: Reddit signup, one-shot purchase, spam test, OTP reception, and receiving mail on a site that filters disposable addresses.
Disclosed bias
Yes, we're both judge and party: mail123.fr is our service. But this comparison isn't "mail123 always wins". YOPmail has longer retention. Guerrilla Mail lets you send emails. Temp-Mail has the largest audience. Our use-case verdicts reflect this.

Verdict by use case
Only mail123.fr offers browser push notifications: enable them on your mailbox and be alerted immediately when an email arrives, even with the tab closed. Perfect for not missing an OTP code.
✓ mail123.fr onlyChoose mail123.fr or Temp-Mail. Both offer instant access without registration. If the site blocks Temp-Mail, try another mail123.fr domain.
✓ mail123.fr / Temp-MailTry mail123.fr with one of its 13 rotating domains (mail456.fr, mail789.fr, mail123.cloud…). Our domains are accepted by most AI services (ChatGPT, Claude, Midjourney…). If one domain is refused, try another. If blocking persists on premium services, only a permanent alias will work.
✓ mail123.frmail123.fr and YOPmail both have public inboxes, anyone who knows the username can access them. For sensitive content, use a permanent alias (addy.io, SimpleLogin). mail123.fr stands out with push notifications: you're alerted the moment an email arrives, even with the tab closed.
✓ addy.io / SimpleLoginFree mail123.fr REST API (50 req/h) or embeddable widget in 30 seconds. Guerrilla Mail still relevant for outbound testing. Mailinator as a freemium team option.
✓ Guerrilla MailIf you need to keep your emails for several days (an administrative form, a delayed confirmation…), YOPmail keeps them for 8 days, mail123.fr for 7. The mail123 address itself stays usable with no time limit.

Frequently asked questions
YOPmail remains functional but more and more sites, including Amazon, PayPal, Discord, block its domains. YOPmail offers daily alternative domains to bypass these blocks, but the practice becomes tedious. For regular use, a service with multiple domains like mail123.fr is more practical.
For simple use (OTP code, quick sign-up): mail123.fr or Temp-Mail. For long-term privacy: addy.io or SimpleLogin (permanent aliases). For developers: Guerrilla Mail (free API) or Mailinator (advanced API, freemium).
Yes, using a temporary email address is perfectly legal in all EU countries. It is a privacy protection tool, not a fraudulent one. Using it to commit fraud (fake accounts, trial abuse…) would be illegal, but the tool itself is not.
Two possible reasons: (1) the site blocks disposable email domains, change domain or try another service; (2) delivery delay, wait 60 to 90 seconds before resending. mail123.fr displays emails in real time via automatic polling every 8 seconds.
Most disposable email services only allow receiving. Guerrilla Mail is the notable exception: it allows sending, receiving and replying from a temporary address. YOPmail only allows replying to a received email. To receive and read your messages securely, create your free disposable address in one click.
