Font size how to increase

How do I increase the font size in incoming emails?

Go to “Menu / Settings (Preferences) / Mail / Read”. Then scroll down to “Preferred Font” where you can adjust the reading font and size as per the help documentation online.

Also “if you click on the body of the email” you can then also zoom the font larger via keys etc.

Pressing “Ctrl & + or - keys” to zoom an email on eM Client for PC, or press the “Command & + or - keys” to zoom an email on eM Client Mac.

You can also press the “Ctrl key & use the Scroll wheel” up and down to zoom an email on PC, or press the “Option key & use the Scroll wheel” up and down to zoom an email on Mac.

To reset the Zoom you can press Ctrl + 0 key on PC or press Command & Option + 0 key on Mac.

Or “Right click” email and select “Zoom / Original

Thanks but having done all that in settings it still stays the same. Am I omotting some kind of confirmation?
