Your audience needs to be listened to. I know this has been driven into the ground, but the curmudgeon really hates it when people don't listen. Most times when I reply to a marketing email with a request and await a response, I get nothing. Thankfully, some of the emails have phone numbers to call, and that works 99 percent of the time and much more effectively than the email method. The basic idea is that when you send out email, you should expect to get something back.
People like to share ideas, concerns, questions, and rants.
If you ignore them, don't expect them to remain customers for long. Pay attention to demographics . The spam-meisters must have known something everyone else didn't. The increase in Spanish-language spam that I have been getting is possibly linked to the most recent Census 2000 findings. The Hispanic and Latino population increased to over 12 percent of the U.S. population, a 58 percent increase since the last census, taken in 1990.
