When I bid any buyer request can I sent my portfolio link with this text?
So long as it’s on the allowed list:
you can add it to your BR response.
If you’ve got it listed on the gig associated with the BR,you can have it linked on the gig, and ask the buyer to check out your gig for the link.
Added - the link won’t be clickable, but you can ask the potential buyer to copy and paste it.
