And once you have confirmed this can then trigger off a whole sequence of emails without any intervention from the person who runs the website. What they do is write up several emails and program these into the Auto-reponder, and they can then program the Auto Responder to send these emails at specific daily intervals. And hence why it is called an 'Auto Responder'.
Of course Auto Responders are used in many different ways, and not just in Internet Marketing.
Besides the basic 'I'm out of the office' message, people can use the email Auto Responder software to thank people for their purchases, tell them about upcoming sales and just about anything a message can send. When a customer fills out a form on your website including their email address, this gives you permission to send them an email newsletter or update on your products and services. It does not give you the right to spam them with lots of updates and requests to purchase items, so make sure you do not cross that line. Perhaps one email newsletter a week would be enough and make sure to have an 'opt-out' section so they do not feel trapped into getting your email, always allow them a way out.
Once someone has made a purchase with your company, from your website, through your affiliate, it's is always nice for them to receive a thank you form you personally, however it's hard to personally thank each customer, so the email Auto Responder software can do this for you. You can program in their name and address, what they purchased and when and send it off as soon as their purchase has been completed, before it's even reached their door step. The message, besides saying thank you for your purchase, can say if there is anything wrong with your product, please feel free to contact me and I will make sure your product is replaced or your money back. It can say anything you want it to say, but people like a money back guarantee, especially from the owner/president of the company.
