In order to carve out time for writing, sometimes you have to draw the line and cut off the email spigot. How?

How? As this 43 Folders article says, this include finding automation and economies of scale. Some examples:

• add info on your Contact page explaining what people can expect from you
• use auto-responses and email template sstating when you are away or can’t be reached
• where necessary send short responses to clarify when you’ll be available again

It’s all about setting expectations.
