AWeber currently has two account options available, a Free account and a Pro account.
AWeber Free
If you're just getting started with email marketing, or only need basic email marketing features, our Free plan might be right for you! Our Free plan has everything you need to grow your business through email marketing with no time restrictions.
AWeber Pro
If you have an existing list of subscribers or want access to more advanced email marketing features such as segmentation, split testing, or advanced analytics, our Pro plan might be right for you! The Pro plan includes everything we offer, including all tools and features as well as unlimited sending to your list. Grow your business with email marketing like a pro.
For Pro accounts we have three base pricing plans for customers with up to 500 subscribers. These plans offer the same services but you will receive certain discounts for ordering the service for a longer period of time.
Billed Monthly: $19.00 per month
Billed Quarterly: $49.00 every 3 months
Billed Annually: $193.80 per year
As your list grows, that billing will increase. To see how the size of your list will affect your billing, or to see a comparison of the features that are available on our Free and Pro plans, take a look at our Pricing page below.
