This requires some explanation. The user signs up and picks a username during the setup. The domain for his email is then created automatically using the formula @username.otherinbox.com. Every email alias that is put in front of the @ will automatically create a new filter and folder for that alias.

This effectively means unlimited email addresses for every user which are harder to guess than those from similar services such as Gmail or Yahoo Mail. This does however mean that every email will reach the inbox and that a new folder and filter will be created for them automatically.

Otherinbox can be used to send emails from the available or newly created aliases as well. The real question is if someone would really need Otherinbox. It is not a problem to create a new webmail account and create filters for marketing and networking websites. The only difference is that Otherinbox provides automatic filter generation while they have to be created manually using the other webmail services.

Is that enough to make the service worthwhile? That’s up for you decide. The Otherinbox team provided Ghacks readers with 25 email addresses. Just head over to http://beta.otherinbox.com/signup/ghacksnet and signup. The first 25 to signup get the beta account.
