I know this thread is a couple of years old, but I've run across the same issue attempting to use custom web fonts in our email templates. I've sort of given up on the idea of being able to fully align our communications with our brand identity, but I'd really like to see this updated in eTapestry.

We would like to use our brand guide to keep our brand consistent but eTapestry does not offer this. It would be great if we had an option to add our font (Franklin Gothic)

Gills Sans MT and Gill Sans would be a big help. Please add more fonts.

Please add Gill Sans MT and Constania

The ability to upload custom fonts in eTapestry should be a priority for the next update. It is important for organizations to be able to maintain consistent brand elements.

Adding extra fonts should be straight-forward. It is very important to maintain our brand identity, and keep communications consistent. Please, please can we add our corporate font. Myriad Pro

We use a third party system for our editor which allows you to choose your fonts.  So, as they update their system, that will flow into eTapestry.  I will put a request into them to add more fonts.

I agree with the above comment.  We use Futura and Geometric Slab as part of our branding.
