While doing marketing, it is always better to take it professional. In the course of taking kt professional, there is a need for the freelancers to have their business emails. This may be different from that of the platform mails. They can be using this to communicate with the clients. When freelancers make use of the regular emails, clients may not take such a client seriously. What do you think of this?
