When I have a new message and want to make sure that it has a uniform format, I select-all then choose the font and size. The font changes, but the size does not - some text remains at a different size. I have to select multiple paragraphs individually and change them in order to get the message uniform.
The above is the bug; the related request is to make the font and font size visible on the top level of the menu and not make user click and select each time.
A related request - make a keyboard shortcut for increasing or decreasing font size, as is available in Outlook ( CMD-< and CMD-> )
If when you select all the text and change the font and size it doesn’t all changes, that usually means "there is some eg: underlying html code preventing it changing.
The only time I’ve seen that is if I’ve eg: copied and pasted text from a webpage. So you might have some font code like that underneath.
So when you get that issue again, select all the text and then cut it and “paste it into either Notepad in Windows or Textedit Mac” which will strip out any preformatted html font code.
Then cut that out and paste that back into the compose window, and then try selecting all and changing font and size and see if that fixes it.
If that still does, could be the fon’t type you are using. Or could be the version of eM Client you are using.
So If the above makes no difference “try different fonts” and also “check your eM Client version is up to date”. You can see all the latest versions of eM Client via the release history page.
