About Mailnesia

Mailnesia is a disposable email service which gives you a temporary mail ID which you can use to register on any website.

Automatically clicks on registration links!

If the email contains activation/registration links to other sites, they will be automatically visited in the background without any user action. This is most useful for registrations or subscriptions on websites where you must click on an activation link in the message to complete your registration. This will be done without any user intervention, even without you reading the email!

Alternate domain names!

Other domain names are available too, in addition to, details on . Of course the domain name has no effect on the delivery, only the mailbox name. So all mail sent to [email protected] and [email protected] can be read in bob's inbox. Expect more names in the future. You can use your own domain name too! Just point your MX record to, setting MX PREF and TTL to something like 10 and 1800. Or if you'd rather not buy a domain, there are also free services like .

HTML support!

HTML formatted emails are fully supported, with a few minor exceptions.

Multiple text encodings!

Many encodings are supported, like unicode (UTF-8), Western/Latin/Central European (ISO-8859-1/2), Chinese, Japanese, Korean etc.

Multipart messages (MIME multipart)!

Messages made of different parts (HTML, text, attachments) are supported, displaying all parts with their type noted. Attached images, files can be viewed and downloaded. Beware though that unsolicited attachments likely contain viruses or scams.

RSS channel for every mailbox!

If you would like to be informed when a new message arrives, click on the RSS button on the desired mailbox page. This way you can convert an email newsletter into an RSS feed! (email to RSS) The following RSS URL parameters are available:

mailcount: the number of emails to display in the RSS, 10 if not specified

format: "html" or "plain", defaults to the one that is greater (in bytes)


Assignable alias for every mailbox

If you don't want anybody reading your mail, set an alias for your mailbox. You hand out the alias, and accessing the messages is only possible from the original mailbox, not from the alias!

Just open a mailbox and click the tools icon to assign an alias for that mailbox. You can set any name you want, as long as its an empty mailbox. Mailbox names cannot be used that are already aliases or have alias associations. The naming restrictions also apply (see at end of page).

For example let's say you assign the alias nudac6 to the mailbox magnic!

If somebody opens nudac6, there will be an error message stating this is an alias, sending mail here is redirected elsewhere, and no email messages can be viewed here. And at magnic you can view the associated alias(es) on the settings page accessible with the tools icon.

Changing an alias and assigning multiple aliases is possible in the settings page accessible from the tools icon.

Deleting messages

Messages are automatically deleted in a short time, usually after a few days based on incoming mail rate. The current value can be found on the statistics page.

You can manually delete a single message with the delete button above an opened email, or wipe out all the messages in a mailbox with the trash icon above the mail list.


Free to use.
