We all know how valuable an active, opted-in email address is these days. Show your appreciation by offering an incentive or coupon in the welcome email -- 10 percent off their first purchase, free shipping or a "subscribers-only" white paper, etc. You want to thank the consumer for showing interest in your company and giving you permission to contact him or her -- so say it like you mean it!
