Great post! I am new to online marketing, my business is actually only a month old and I too am using Aweber. I have found it really simple to use and I love the reports section. I am an analyst by trade so this is so up my street! I came across your post as I was interested to find out how Aweber compare to other autoresponders and if I’d made the right decision. Your post has told me I have. I will look forward to reading more of your reviews and tips.


Just in case you’re new to the whole email marketing landscape, Aweber (along with MailChimp, ConvertKit, InfusionSoft, Ontraport and countless others) are email marketing systems designed to allow you to capture subscriber emails and then send them direct messages straight to their inbox. Some are very basic doing only email marketing, and some are full service systems that also include commerce and CRM capabilities.
To start, you’ll have 700+ templates to choose from. There are some very nice layout customization options here, once you learn how to use them. AWeber uses both “sections” and “blocks” in its organization. Blocks are elements like text boxes, images, etc. Sections are the frameworks in which they exist. Most programs use similar organization, though they may use different terminology. The difference comes in your ability to edit or customize the sections themselves. In previous versions, the ability to customize elements like buttons was limited–you couldn’t change the text of buttons–but you now have the ability to easily customize those elements.
Using the Personalize dropdown, you can insert custom snippets like your subscribers first name, or sign up date, and AWeber will automatically insert that data specific to each subscriber if we have it. If you collect first name, for example, you can send an email that says Hello Tom, or Hello Mary, or Hello John, depending upon who you’re sending to.
