Graphic design in social media

Hi, I´d like to know if we can use one Envato signature in social media design for many clients. We are an agency.

you have to purchase individual license for each client.

I´m confused yet. Do I have to pay one Envato signature for each client or I have to simply download the license for each client?

you have to purchase individual signature for each client because each client will use the signature for their end product. One license will work only for Single user.
