About the mailbox Beta program

The mailbox Beta program includes previews and early versions of new features that are still under development (beta phase). With your help, we would like to test and further develop these features before making them available to all users.

By joining mailbox Beta, you will receive exclusive access to the testable features. Our principle also applies to beta tests: we do not collect any personal metrics. Your data remains your data at all times.

In order to test and evaluate the features provided through the beta program, we rely on your participation. As a member of the beta program, you therefore allow us to occasionally contact you by mail, for example with news about the beta program or for (anonymous) surveys among members of the beta program. Responding to such surveys is, of course, voluntary. You may also end the beta phase at any time.

Please note before joining

It is characteristic of a beta phase that when using new features, errors may still occur, the system may behave unexpectedly, or the service may be unavailable for a few hours during updates or maintenance. These may be features that are not yet fully mature. It is also possible that these features will be removed again if they prove unsuitable for productive use.

Therefore, do not register as a beta tester if you use mailbox for business-critical processes or if, for any other reason, you rely on the error-free operation and uninterrupted availability of mailbox.

We look forward to your participation and feedback!
