5 steps to building successful email campaigns include: 1) designing emails for deliverability, aesthetics and message; 2) quality assuring emails by testing on servers and browsers before launch; 3) segmenting internal lists of subscribed consumers by demographics like age, interests and location to match targets; 4) delivering emails with a no-cure, no-pay policy; 5) quality controlling by removing unresponsive leads and archiving them to ensure efficient and effective delivery.
