1. Adobe Stock doesn't sell fonts. They sell licenses to royalty-free assets (photos, graphics, templates, video & audio clips). See Adobe Stock License information below.

2. Adobe Stock doesn't accept templates from regular contributors. If you sell templates through other sources, don't assume anything. Read the font license very carefully to ensure you're using it legally.
3. Adobe Fonts can be used for logos and flattened image files that the customer can't edit. But if the customer wants to edit text and re-use that font, they'll probably need to purchase their own font license. See below for more details.

4. Adobe Express is another service entirely. See below for more details.
