## Help mailcow

Please consider a support contract for a small monthly fee at [Servercow EN](https://www.servercow.de/mailcow?lang=en#support) to support further development. _We_ support _you_ while _you_ support _us_. :)

If you are super awesome and would like to support without a contract, you can get a SAL license that confirms your awesomeness (a flexible one-time payment) at [Servercow EN](https://www.servercow.de/mailcow?lang=en#sal).

## Demos

Since September 2022 we´re providing two seperate Demo instances: 

+ **[demo.mailcow.email](https://demo.mailcow.email)** is the classic Demo based on the **stable releases**.
+ **[nightly-demo.mailcow.email](https://nightly-demo.mailcow.email)** is the new **nightly demo** based on unreleased testing features. (So especially interesting for those who have no possibility to create a test instance themselves.)

Use the following credentials to login on both demos:

- **Administrator**: admin / moohoo
- **Domain-Administrator**: department / moohoo
- **Mailbox**: demo@440044.xyz / moohoo

!!! success
	The demo instances get the latest updates directly after releases from GitHub. Fully automatic, without any downtime!
