I tried rightclick on email body > Services > Display Font Information > Run Service confirm, which gets you to User fonts. I'm trying to delve deeper into this functionality but not sure I'm on the right track. Hard to believe that Appearance targets the 'outer' UI, but not the display of messages themselves (font family, weight, size), things that are pretty much core functionality in email apps, or so I thought... Even Eudora had this, didn't it?

I adjusted my display to scaled in system preferences. This seems to work.

Please add font size control for the display, the text is too small and for people with poor eye sight the app cannot be used. Great shame as otherwise this is an excellent app.

Has this issue been resolved? Definitely need a way to change font size for this app to be of use.

I need this as well.

Totally agree. The font face is also a bit questionable. 1-2 pt bigger font size plese ASAP!

Need font control for all different font sizes. For me, the sender name in the message list is much too big.

Bigger fonts please!

Please resolve the font size issue. My customers complain about the font size they see on the recipient end of the messages and I can't see the font when writing email without the CMD + work around. This issue has me actively looking for a better solution.

Agreed. I have to type CMD + each time I compose a new email. It would be great to set this up as a standard preference (ie set and forget).
Please implement!!

Not just size; let us pick a font face too, please.

Completely agree. Much needed feature.

Yes absolutely-- this is a major oversight and given all the customization it's surprising there are no text size (accessibility) controls. I can't use it.

I'm loving AirMail (for Mac OS) except for the microfont size that I can't find a way to change. How long before we can get a preference for changing the default display font size to something that is legible for old eyes or people with visual impairments? Accessibility is very important!!

I just installed and configured Airmail 3 on my 27-inch iMac and my issue is the same as above. Why is there no feature to adjust the font size for comfortable viewing on large hi-res displays? It's a great app otherwise, but if this basic feature is not implemented I probably won't continue use it for very long. Too much eye strain! Come on guys, this has been an issue for some time based on previous comments.

We want to change both font size and default fonts too

Same here. When composing a new message I need to "zoom" every time. At least retain the previous zoom level when composing new messages.

+1. please.

I really wanted this feature as well. But you can just go cmd+++ and it will zoom in the emails that you view. I have a large screen as well but zooming in, works just as good.
