Not everything, but a lot. Phone calls, video calls and appointments are also possible. I do a lot via e-mail so that all specifications can be found easily, and no important things are left out. For larger projects, it is nice to call or speak to each other via Zoom to brainstorm together, for example. And sometimes it is convenient for me to come to you or for you to come to me, e.g. for me to look at something to draw in the assignment. This will be especially for long-term projects. I don't discuss anything business-like via Whatsapp, SMS or social media DMs. Important information quickly gets lost in all kinds of inboxes. So I do not respond to these messages so that I can deliver better work.
