using autoresponders to make money

Autoresponders are email programs that can schedule and send emails to addresses automatically, based on arbitrary criteria. They can be extremely simple or hugely complex. They are often used to assist in the management of email lists.

Autoresponders are a great way to automatically contact your subscribers. If used smartly, they can save you an enormous amount of time and produce sales from your mailing lists through automated follow up on leads. Here are a few examples of ways in which you can use autoresponders:

* Automatically send a follow up email to customers who have bought products from you.
* Follow up with customers who download your free e-book/s or other “ethical bribe” products.
* They can be used by technical support to tell users that you have received their message and will get back to them soon. Such messages are important because they reassure your customers that their support request has arrived at its destination and will be attended to when you are available.
* Send prospective customers product price lists, your FAQ, and other fixed information. People emailing the autoresponder address you specify will automatically receive the information they require.
* Send email course modules. For example, if you have a three week course that requires course information or documents to be sent to your students once a week, you can simply request your students to send their addresses to your autoresponder. The autoresponder will then reply to your students with the course package at the scheduled times.
* A variation of the above is used by some webmasters to sell courses. They advertise an email address that customers can contact to receive a free sample of a course or book. The autoresponder then sends a few chapters from the course or book to the customers over three successive days. On the fourth day, the message asks the customer to sign up for the rest of the paid course or book if they wish to continue. Since the customer has sampled several segments (or chapters) of the course or book, he/she is able to decide whether or not to continue. If the course or book is particularly good, the autoresponder segments can be an effective way of persuading a customer to buy that product.
