You can find numerous options when you login to your AWeber account. You can choose whatever you would like to do without having to going through each and every option. You can also find a progress bar in your AWeber account that lets you know about your progress as well as about the remaining steps. AWeber also presents guides and videos that will make your work much easier.
For example, if someone is on your list and they choose to unsubscribe later, they still count as an email in the system which is included in your total subscriber count. You must fully delete that record from your account in order to not have to pay for it, and so I found myself going into each of my individual lists and deleting unsubscribes from my account about once a week.
Before you can send AWesome emails with AWeber, you'll need someone to send it to. The easiest way to begin building your list is to import contacts that have opted-in to your email list, or gave you permission to send them emails. These could be subscribers you've emailed from another provider, or a list of contacts that you've built through your business.
