List building is probably the best way to make money online. It's possible you have heard the saying plenty of times by now, the money is in the list. Just what does that mean?

The phrase "the money is in the list" is making reference to e-mail marketing. What it basically means, is that you're going to earn more income if you establish relationships with your shoppers by encouraging them to subscribe to your mailing list.

All flourishing businesses understand that return shoppers are what drive a business. In the world of Web marketing, the obvious way to get return customers is by getting them to opt-in with your Auto responder. An auto-responder can set you up with several different quick ways to make money.

An auto responder allows you to communicate with your shoppers. This communication is vital if you want to sell products on the web.

Because your auto-responder will probably be your major source of contact between you and your subscribers, it is extremely important that you choose the right service.

Below are three things to think about when looking around for an auto responder service.

The importance of delivery rate: If an auto-responder service has a good delivery rate it simply means that your opt-in list are more likely to receive an e-mail when you send an e-mail to your subscribers. Having poor delivery rate means that the majority of your e-mails will not be getting through to your members on a regular basis.

Delivery rate is possibly one of the most important factors to consider in e-mail marketing.

Shop around for different prices: There are many recognized auto-responder companies to choose from. Once you have determined auto responder has the best delivery rate, the next action is to search for a price that will work with your funds.

Some services will charge you one set price despite the size of your opt-in list. Other services will charge more as the size of your list continues to grow.

Reputation and brand is also important: There are so many autoresponders to choose from. When performing research, be sure that you have a look at reputable businesses.

The three factors mentioned can mean the difference between a successful e-mail marketing career, and one that fails to gain momentum. If you are looking for ways to earn extra money, then list building is most certainly a possible option.
