Runbox is a fully-featured email service that you can use with your web browser, an email program like Thunderbird, Outlook, Apple Mail or with your mobile phone.

Runbox 7 launch for new customers

Starting in 2020 new users will be given the new Runbox 7 web app as their default webmail interface. The help documents on this website mostly relate to the older Runbox 6 interface which is still available to all customers.

You can find a dedicated Runbox 7 Help page and a series of blog posts about the new features in Runbox 7.
