How to increase email response rates

Does it frustrate you occasionally that important emails, calling for action, aren't answered ? Is it because you're writing to multiple people with one mail ?

There is an identified social phenomenon known as the Bystander Effect. Test after test has proven that groups of people do not act, but individuals do. For example, in a study done at Princeton University where an actor faked an epileptic fit in the street, if over 5 people were present, there was only a 1 in 3 chance that someone would stop and help: most hurried on by, not wanting to stand out from everyone else. But when only one person was walking by, there was an 85% chance they would stop and help.

So how to get maximum response to your important emails ?

Send it to only one person at a time.
