Here’s a collection of the best free email services that allow you to send emails anonymously. Although some ask for personal details during signup, that’s typically only to help you recover your account if you forget your password.

GuerillaMail

GuerillaMail provides a free, disposable, self-destructing, temporary email address. No personal data is required. Use it once or until you see spam, and then delete the account. If you use an Android mobile device, download the app.

  • Offers both temporary and permanent email addresses.

  • Messages self-destruct.

  • Requires no personal details.

  • Temporary mailbox works for only 60 minutes.

  • Interface is very dated.

5yMail

5yMail includes an advertisement at the bottom of each email and permits you to send to only one recipient at a time. If you want a reply to your email or want to attach files to emails sent to multiple users, upgrade to 5yMail’s paid service.

  • Delivery receipts, including dates and times.

  • Scheduling capability.

  • Ad at bottom of every email.

  • Can send to only one recipient at a time.

  • Extra features require paid subscription.

Anonymouse

Anonymouse lets you send an email without entering any personal information at all. That doesn’t mean you can send anything you want, so be aware of the legal ramifications before you send an email that might not be legal.

  • No registration required.

  • Free version supports up to three attachments per email.

  • Advanced features require premium subscription.

  • Delivery often delayed.

W-3 Anonymous Remailer

W-3 Anonymous Remailer provides email fields for the receiver’s email address, a subject, and a message. It’s difficult to locate any more information about the service, which, considering its purpose, is probably a good thing.

  • No registration required.

  • Simple and quick to use.

  • Completely untraceable, unlike some other remailers.

  • Lacks support for attachments.

  • Dated interface.

Send Anonymous Email

Send Anonymous Email has a plain interface to enter the receiver’s address, subject, and message. No other details are required. The site warns if you send death threats, abuse, slander, or anything illegal, it will publish your IP address and block you from the site.

  • Claims to be world’s largest, most trusted anonymous email service.

  • Offers support for abuse complaints.

  • Doesn’t support attachments.

  • Snarky language in interface detracts from perception of legitimacy.

Other Options

Some services ask for your email address or other personal details; some record the IP address you use to access the platform, which could monitor your IP address. To send a truly anonymous email, send it through a chain of remailers and remove all traces that lead to you. Likewise, consider using a VPN (virtual private network).

Most of these services have a disclaimer of some kind that warns against using the service for illegal activities. Prank, fake, or threatening email messages are fraudulent and unlawful. If a message is commercial, then it is spam, and U.S. laws, such as the CAN-SPAM Act, apply penalties to nonsolicited messaging and the distribution of obscene content.
