Easy, let the user opt in to email updates about new products, rather than automatically "opting" them in when you force them to use their email to create an account

> Basically...I just don't know what communication medium would allow a company that makes app icons to keep their customers in the loop about updates & concerns related to the product. Are you gonna install a Font Awesome app?

What companies _used_ to do is have "Subscribe to our newsletter" on their site - either for non-account holders, or as a separate checkbox when setting up an account.

Same with email frequency — would be trivial to add "when do you want to hear from us?" as a question "when we release a new font / when we make changes to a font you've purcahsed / only account related".

We have the patterns for all this already established.
