Changes to the newsletter

We have made some optimizations to our newsletter system.

Firstly, the weekly newsletter will now be sent every Sunday. This should give you a better overview.

Secondly, we have fixed a minor issue with our newsletter system. There were times when we did not publish any new items or changes in the shop, but still sent a daily newsletter that did not contain any relevant content. We have now improved this and will only send you the newsletter on days with relevant news in the future.
