I got free themes from envato by mail. Can use these themes for my clients. Is there any issues for the linces
The free themes come with a standard single license. So it’s possible to use them in a project but you won’t receive updates or support for them, so it may be a bit risky to use them in a client project
No. that is not allowed as per their T&C, as it is single licensed.
They are single use licenses, but they can be used for clients.
