This is a simple case of "we" and "you" having different points of view. Sure, "we" think we have something fun to share, big news, we haven't emailed in a couple of months so users are probably anxious to hear from us. "You," the user, is getting 20 emails a day from people who think they are sharing something fun, only emailing every couple of months. They're flagging all that as spam, and that's why Gmail won't send your spam anymore.

About the clearest case of "It is difficult to get a man to understand something, when his salary depends on his not understanding it."

That is the thing. If I sign up to a fonts website, I may be interested in fonts. Finding new fonts, the history of fonts, obscure lineages, how to use them, that stuff.

Give me that in a newsletter and I might read it. Give me some info about an "awesome" new "release" and lose me. That release is important for everybody working there, but outside of that it id irrelevant as a story.

Wanna sell a new industrial font? Write about interesting industrial fonts and then in the end tie it to yours. People that read that far may just click and buy.

Zero emails is not low noise - it's zero noise. I agree that I sometimes want zero noise from companies whose products I am using...and also it depends on what is in the noise? Sometimes I find unexpected signal.

I would say that email is inherently a somewhat noisy channel. You have little meta-data about how appropriate and timely a message is, so often you are sending in the dark. There are many downsides to the protocol and its place in our lives but it does carry a lot of important communication.

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?
