Update: OK I understand what you mean now and I have tried it. That enlarges the size of ALL other fonts in the phone as well and makes it totally useless. And still your newsletter is to small. No I am sure this has nothing to do with my settings as they have worked fine one decade with different Android phones. If I enlarge the fonts I will not be able to use the other emails. I guess, if I want to read the newsletters, I need to work hard with my fingers and zoom entirely. The old newsletter was much better regarding this aspect.
