     Have you ever asked your customers and potential customers how they'd like to hear from you?Some
of them might check email messages regularly throughout the day; some of them might check their messages only once or twice a day; and some of them might not use email at all.
     If you've been automatically using email to avoid lengthy phone conversations, first check to see if that's
also your customers' preferred method of communication.Then consider the benefits of picking up the
phone.
     I know, email is convenient.It gives you a record of what was said, and it lets you communicate without wasting any time on chitchat.But it also removes that little human bond of friendliness.It prevents you from
finding a common ground-such as a shared interest in a hobby.The phone allows that.
     Using the telephone also aids in communication.A misunderstood question in an email can take several
messages back and forth to clarify.On the phone you can say "No, I meant..."and then you can restate your question in a different way.Instead of being a timewaster, the phone can sometimes be a timesaver.
     Be sure to ask your customers if they'd prefer documents sent to them by email or fax -because some
people really do prefer the fax.Remember that they're busy too.They might not want to sit at their computer opening files and printing pages of documents.For some, it's much more convenient to walk over to the fax machine and pick up the preprinted documents.
     There's an old saying:People don't care how much you know until they know how much you care.Let
your customers know that you care about communicating with them in their way.Asking is merely adding
another level of customer service.
      Knowing how your people like to communicate can be even more important with prospective customers.
      Say you're sending a proposal for a project and competing with another vendor.If you assume that your prospective client reads his or her email regularly you might transmit your proposal as an attachment.
     If your assumption is wrong, and if your competitor has taken the time to learn that your prospective
customer really wants to receive documents via fax, your prospective client might not even see your
proposal until after the job is awarded.
      It only takes a minute to ask the question, and it might make a big difference in your income.
