Make the signing up process incredibly easy. Remember to send the acknowledgment message. If your mailing list has swelled up exorbitantly, then it would be advisable to use an autoresponder rather than trying to send personalized acknowledgment messages.

Try to retrieve demographic information. You can either add related questions in the subscription form itself or you can attach a short survey with the form. Demographic information will give you a fair idea of customer location, interests and behavior. On the basis of this information, you can adjust your promotional materials and offers. This tactic will certainly increase the response rate and thereby profits.

Always leave your readers wanting for more. This will keep their interest alive as well as make it easy for you to sell your products and services. Hence, don't stuff all the information in one message. Divide things, and deal with the most important thing first. Leave the rest for future communications.

Never flood your subscriber's mail box. Prepare a plan that would help you to stay in touch with your subscribers plus give them time to digest the piece of information you have provided.
