If you use email, you know how much spam rubbish and general clutter floods into your inbox. Some estimates place the amount of unwanted email traffic at 95% (fortunately most of it is filtered out before it afflicts you). Yet despite this white noise, email is still one of the most powerful marketing channels, social media notwithstanding. Most people still maintain an email address, and most still read their email. If you have clients and potential clients you'd like to reach, email is a very good place to start. But beside coming up with attractive, interesting content, you will want your email communications to look professional, and you will need to track the metrics of your various email campaigns. Vision6 and MailChimp offer users a low cost and easy-to-use entry to the world of email marketing. MailChimp in particular offers an absurdly generous free service to users generating less than 12,000 emails per month. Plus they have a cute monkey avatar that dispenses cheerful backchat.
