I thought this might prove useful to some teachers.
Here are some tips you might like to help you manage email fast and forever (and yes, they do include the delete key).
http://five.sentenc.es/ (very brief justification of five sentence rule, also leads to the more efficient two sentence rule – how low can you go?)
http://elearningstuff.wordpress.com/2007/10/01/dealing-with-e-mail/ (video is one hour lecture – watch if interested. It’s a good lecture.) Good quick advice in this post:
# Delete or Archive
1. Good email signature (not so relevant for internal mail in a school, except for your phone extension)
2. Edit the subject line of your email reply to give the response e.g.<— Yes (or no?)
3. Don’t be afraid to be brief: aim to further or complete the conversation (you are not being rude, just efficient)
4. Use decent grammar and capitals but don’t create literature. Any more than two/three minutes and you should be creating a document or blog post for future reference, or using the phone or going to see them.
The delete key is not always the answer. But your time is precious so respect it by not writing long emails, and so will I.
