AT:

• testsystem has its own database, (no copy of prod users!)
• testsystem uses its own mailchimp list (can be just one)
• testsystem is available under its own URL
• testsystem hat its separate jenkins job

Question:

• anything we need to take care of for the mails which are not sent via mailchimp?
• Should we use a similar (master -> live) mechanism as for the docs?
