Customising the font on a newsletter (including header, footer, buttons etc)

Site URL: https://www.manderleypress.com

Hello everyone, I'm relatively new to Squarespace but have found this forum very useful - I've managed to customise my site to include my own font and have been tinkering away with bits of recommend css code so that most things look the way I need them to.

However, I have reached a stumbling block with my first newsletter. I simply cannot get it to use my own font, either in the main body or in the endings or the footers etc. What am I missing?

Any advice gratefully received.

This isn't possible. Newsletters must use a font that will be installed on the recipient's device, so you must use one of the fonts provided.

That makes sense! Thank you so much for taking the time to respond.
