Subscribing Those Who Send You E-Mail

"If I send my sales letter/update to an Internet business professional who has e-mailed me several times promoting his various products, is this okay?" -- Faith Call

The question is whether you have received permission to send e-mail to someone. Kindly request permission to send your sales letter, then wait for permission. Hundreds of people subscribe me to their newsletters without my permission, so I end up getting thousands of pieces of unwanted and unread e-mail that is the equivalent of spam. Respect your recipients' preference!
