Don’t know if this has been mentioned by anyone but, in Mail app on my mac at least, a lot of the links in your emails don’t appear to be proper web links and therefore don’t work. I am referring to the Lick of the Week email I received this morning as an example. “Log in”, “Step-by-Step Harmonica Course” don’t open a browser window.
Obviously can get to them other ways but just thought I would mention it. The .com links seem to work fine.
