This was all possible with Aweber, with some drawbacks (and one of the reasons I switched to ConvertKit). While you could set up an autoresponder sequence in Aweber, it was not easy or convenient to segment out those users who were in the sequence from getting your main newsletter or blog broadcasts. So, it was possible that people were getting multiple emails from me a week.
Even if you've imported an existing list of contacts, you'll still want an easy way for new fans to join your email list. AWeber's sign up forms provide the perfect solution. Create a simple sign up form for your website, and if you don't have a site, we'll host it for you. Grab the link to your AWeber form and share it on Facebook, Twitter, LinkedIn, or wherever your audience is.
