Path to the logo seems to be wrong..
The Logo is not shown and my domain is wrong.
The domain should be mydomain.com, but it is mydomaincom
Does it work when you go to "Settings => Email Reports" and then click "Download" on a specific report?
Displayed normally there..
I tried differnet Mail-Programs, same problem everywhere
Thx, looks like a bug in Piwik and we need to try to reproduce
