I have handled email lists and published e-newsletters for several clients in the past.   I always insist my clients comply with SPAM laws and grow their email lists through traditional means rather than sending it to everyone who drops a business card in their fish bowl at conventions.

Many people think of email marketing as a cheap, impersonal way to market.  It’s not.

Email is very personal to the person who receives it.  Many people think of email as an imposition - a necessary task that keeps them from getting things done.  E-newsletters should be informative and enjoyable first - a sales gimmick last.

Just like Justin at AWeber, I get offended when I get emails I did not explicitly opt to get.  Here is Justin’s take on it.  It may be worthwhile to read the comments below it as well.
