Very bad
Awful. The number of lines you can use in the recipient’s address is very limited. The developer insisted on including the zip code on a separate line which burns one of the available lines. I couldn’t figure out how to change the font size. The default font size is way too small and the default margins, which I also couldn’t find how to change, are ridiculous. The sender’s address is at least 1.5” from the left edge. The help document is incredibly user unfriendly. Just a massive waste of time. Avoid it.
