One account also means one point of contact. He or she may be a marketer who has to accomplish a lot of graphic design related work in a day, we are very happy to help him or her to complete them.However, there are instances where within one company there are two to three marketers working on different or same projects at one time. In this case, each of this marketers would need to sign up as one user with one email address, even though they are representing the same company.Sharing account in this example would also mean one marketer is making all the requests on behalf of the other two marketers. We want to ensure quality work is done for all our clients and hence do not appreciate such workaround. We hope you understand.
