I just read a fantastic article by Anna Papadopoulos that should serve as a good checklist for determining when it’s appropriate to send an email. I always caution employees to be careful about email and to never put anything in an email that they wouldn’t want their boss/mother/CEO/etc. to read. Things get forwarded, printed out, shared, etc.  You just never know where your email will end up once you click send.

Here’s Anna’s article which sums it up well:

Here are some more of my thoughts on email etiquette.
