I can send drafts of different documents between the client and myself and get responses within the same day. We can edit the document more efficiently by not having to wait a few days for it to arrive. This is handy to send documents that are only on the computer back and forth on-site as well. However, it is more useful when communicating with the client in New Jersey or other trainers down in Florida . I tend to only use the phone in urgent cases.
Voice mail is very handy.
I will only use e-mail if I can allow a reasonable amount of time to await a response. I will use the phone for information I need immediately. I notice you haven t said anything about the fax machine. Sure, there is still a need for faxes. For example, I still have several documents that are only available on hard copy and the fax machine is the only way I can quickly get the documents to off-site locations.
