Languages currently being translated include: German, French, Spanish (Spain), English (British), Italian, Dutch, Portuguese (Brazilian), Russian, and Swedish, with more on the way! If you would like to help us localize Postbox, please visit our translations page!

You bet! Postbox lets you keep existing email addresses and accounts. In fact, we make any webmail account even better by making it easy to find and use almost anything from your webmail accounts.

Postbox and Gmail work beautifully together, a match made in heaven. But there are some important differences between Gmail's webmail interface and Postbox that you should know about. Please see our Using Postbox with Gmail page.

Postbox currently supports POP3, IMAP, and SMTP protocols, so if your administrator has those protocols turned on in Exchange, then you can use Postbox to send and receive mail from those servers. Postbox does not currently support native Exchange protocols.

Not directly, but you can use the Lightning calendaring extension within Postbox, which provides an integrated calendaring experience. Please see our visit our Lightning page to learn more.

Yes! Please see our Add-ons Center for a list of add-ons that provide support for Postbox.

Postbox provides a mechanism that allows add-ons from 3rd party developers to be installed within Postbox. However, it is up to each add-on developer to support the functionality of their add-ons they author. Postbox does not provide support for 3rd party add-ons.

Unmodified Mozilla add-ons do not work within Postbox at this time. Developers of existing Mozilla add-ons need to port their add-ons to Postbox. Sometimes this can be as simple as changing a few parameters, such as product, version, etc., other times the porting effort may be more complex.

In some instances, such as Lightning, Postbox has performed the necessary porting work to get an add-on to operate within Postbox. We do this so people can get an early feel for how key add-ons will function within Postbox. But we do not support these add-ons, again, because we did not develop them.

We work with extension developers as much as possible, but if there is a particular add-on that you really like, our suggestion is always to contact the add-on developer to have them port their add-on to Postbox.

Postbox Express 1.0 is a simple, yet powerful, new email application for Windows and Mac. It's based on the same platform as our premium version of Postbox, but contains a lighter-weight feature set that's perfect for home use.

Best of all... Postbox Express is completely FREE!

Postbox Express is perfect for people with light-duty email needs, such as students, retirees, or ski bums. It's a great alternative to other free offerings such as Thunderbird, Apple Mail, Windows Live Mail, or Eudora.

Postbox is a fully featured email solution that provides powerful search, organization, and productivity tools for busy professionals. It contains a much larger feature set, more frequent releases and a faster pace of innovation, which makes Postbox feel more "alive" and relevant than other desktop email clients.

To learn more about each edition, please see our handy comparison chart.

Postbox Express and Thunderbird are both based on Mozilla® technology, but Postbox Express offers simplified account and folder views, powerful search features, more complete conversation views, and a gorgeous user interface. Learn more about why you should switch!

You bet! Postbox Express will import your Thunderbird account settings, email messages, contacts, filters, labels, and junk settings - everything you need to get up and running in minutes.

Absolutely! Because both products share the same configuration files, an upgrade to Postbox is completely seamless and hassle free.

Yes, both products share the same configuration files, so you can easily move between the two.

Windows and Macintosh. Please also see our System Requirements.

It's FREE!

We will be highlighting what's new and cool about the premium version of Postbox within Postbox Express, and hope that at some point you will be compelled to upgrade. We may occasionally present special offers, or experiment with other ways to provide value to our users, but our initial focus will be to promote the premium version within the Postbox Express start page.
