A better question might be "Who are you communicating with?" and then "What are they capable and/or accustomed to using?" If you're just dealing with other IT industry types, then email may not be for you. OTOH, if you're dealing with other industries like real-estate agents, lawyers, shopkeepers, etc. (non-IT people and/or non-technology-centric people) then you may find that email and faxes are the way to go.
