Thank you for reaching out. In order to answer your question " Can I use web fonts for my client websites?"
Yes. You can create digital designs or print work for your own use or for client projects. This includes generating a PDF, EPS file, or bitmapped file such as a JPEG or PNG.

but I don't understand why people in Adobe don't pay attention to requests, they don't read what I write.
I ask for using font in websites of my customers.
I can't open, for each website, a new Adobe Fonts account. Is there a way to use fonts for customer websites using an Agency Account??
