Email 98% of the time. I also take care to explain very well to all my contacts, face to face, why I prefer email, how I work and so on. Practically everybody respect my choice and it really works. I can dedicate time to dealing with request and they don't interfere with other aspects of my work and personal life. But I am flexible: sometimes a synchronous channel is needed, for example to mentor a new employee. There is nothing wrong with it as long as it's of limited duration.
