Your BRAND is important enough to have constant contact with your clients and potential clients. An Auto Responder can provide you the opportunity to keep that contact. You can follow up with those individuals that want and need your product and services on a regular basis.
Auto Responders allow you to type a follow up letter one time and send it to everyone. They also allow you to notify clients of upcoming deals, or help them solve a problem.
Auto Responders can send your product or service right into their Email.
I personally use Aweber and absolutely love it. Here is a Link you can check it out for yourself.
