Jason Cupp shares an (all-too-familiar) example of email marketing gone wrong.

Recently, a friend forwarded me an e-newsletter from someone in the landscape industry.  I’ll admit it – it was one of the most poorly written, borderline offensive, anti-brand, culture ripping emails I’ve read in a long time.  I was really embarrassed for this company – which is why my friend sent it to me.

Technology makes it easy to set up and blast out e-newsletters, but that low barrier to entry can backfire.

Check out Cupp’s blog to see how.
