When working in your AWeber account, under the "List Options" tab there is a section for Email Parsers.
If you click on it, you'll find a page filled with checkboxes next to the names of several third party services.
What Are Email Parsers For?
An email parser is a technology that allows you to integrate your campaign with these and other services so that when a transaction is made with that service, a subscriber can be added to your campaign.
For instance, you might use Volusion as a shopping cart for your products. You can use an email parser on this page to automatically subscribe customers when they purchase from you.
How Do I Use the Email Parsers?
Under the Integrate category in this Knowledge Base, you'll find tutorials for many of the services listed on the Email Parser page.
If you are using a service that we don't already have an email parser for, you may want to look into using the API to add customers to your lists.
