Having your clients as Instant Messenger contacts can improve your efficiency in project work. You can get a fast solution to road blocks and solve little problems quickly, as well as develop a better relationship!
Of course any important chats should be confirmed via email.
Hey Simon,
I find having my clients available on Skype is extremely useful. Are you on Skype? If so, can I please add you as a contact? I'll add the above email address, let me know if you use a different one.

Figure: It's easy to get your clients on IM, you only have to ask!
