I was looking at the email addresses of my customers and see that lots of them are from hotmail, yahoo, and aol. Since all three of those have corrosponding IM programs I am debating on having customers contact me through IM for questions, suggestions, etc. Has anybody else used this as an effective way of communicating with their customers or would this be seen as bush league? I just set it up today so it is too early to report any results but if anybody has any ideas about this I would be glad to hear them.
