I guess it depends on where you are from. Here in my country you just do freelance with your name and that’s it. I also just use my normal email, so there’s nothing to it really. But I bet in the USA it is very different, so other people would have to say. But same for having a webpage, I don’t know if people use it at all these days. Mostly potential clients would ask me where they can see my work and they always ask for my Instagram more than anything. I don’t use social media but I had to get an Instagram because so many people were asking for it.
