If you are a beginner and want to try any rocking email marketing software, MailChimp is for you. You don’t have to even use your credit card to use MailChimp as you can get it for free (upto first 2000 subscribers). But the pricing becomes much more than AWeber once you start getting more than 2000 subscribers. So it again depends on your website email marketing needs.
Basic: Each week I send out an email about my latest podcast episode. Now, I create a rule that says that if they click on the link inside my email (sending them to my show notes page), they get tagged as Interest: Podcast. That means, should I ever want to send an email to those that I know are interested in my podcast, I can just select this tag. Easy.
