Currently we can only have folders at the top level of the email templates list. Our agency manages photography studios who send comms to leads and to clients, and it would be immensely helpful to have the ability to nest sub-folders within the top folder hierarchy to better categorize and locate certain email templates. For example, we would use it like this:

Email Templates > Leads > Photography Genre > Initial Contact

Email Templates > Leads > Photography Genre > Nurture Sequence > By Month > 01. January (etc)

Email Templates > Booked Clients > Photography Genre > Prep Emails

Email Templates > Booked Clients > Photography Genre > Pricing Emails

Email Templates > Booked Clients > Photography Genre > Photoshoot Confirmation and Reminders

Email Templates > Past Clients > Review Requests

Email Templates > Past Clients > Nurture Sequence > By Month > 01. January (etc)

...and so on.

Right now, since we can only have folders at the top level, it is difficult to find emails, especially if you have a lot of them. The ability to nest folders within the top folder level like we can in Workflows and Custom Values would make a huge difference in organization.
