"How to send a personal email" by Seth Godin
“How to send a personal email” by Seth Godin gives some excellent suggestions about how to avoid being perceived as a spammer.
But there are no easy answers. Basically his 14 points boil down to taking the time to make your email short, clear, personal, and relevant to the recipient.
I found Godin’s blog post thanks to Anna Goldsmith’s “Just Because You Have Someone’s Email Address Doesn’t Mean You Have the Right to Email Them.”
