Why do some freelancers close deals over email while others require multiple calls?

Hello BMFers,
I am writing this to ask why some freelancers always prefer sealing their deals on emails and not several calls. I have met with different freelancers and I discovered that majority of them always prefer getting sorted on emails and not several calls. Some believe that several calls will be a kind of disturbance to them. Some people say email seems very remindful as they can check what they forget in the emails

I will assume that the one that uses call was able to pinpoint the problem of the client and it was able to close it with the message in his email. And those who are using voice call my not be able to achieve that within short period of time. If you do the writing irrespective of the medium you will get the right answer
