Never use email when you are angry. If I want to delete it, I can. If I want to keep it, I push a button and there it is to preserve for posterity. I am a die-hard email person. No one seems very wound up about fax faux pas.
Faxes are passive and easily ignored, unlike email, which always seems so urgent.
The major mistake reported is leaving out the number of pages being sent. Spam faxes are an annoyance to some. I keep getting faxes from a company polling me about some important issue, even though I ve never replied to any of their previous faxes. They don t give up. The last one, a week before the election, asked me to vote for my presidential choice using one of two 900 numbers.
