Do you have an opt-in email list?  A recent survey by Q Interactive and Marketing Sherpa, called the “Spam Complainers Survey,” revealed some reasons why people mark certain messages as “spam” – even when they are not spam by definition (unsolicited and unwanted email).  56% feel email from known senders is spam if it’s “just not interesting to me” 50% believe “too frequent emails from companies I know” is spam 31% are irked by “emails that were once useful but are not relevant anymore” This research should make email marketers nervous — opt-in subscription is not enough.
