AWeber released a WordPress plugin a while back, but I didn’t bother installing it, because I already had their email optin forms built into my WordPress template.
But now it includes a cool, new feature that allows people to sign up to a list when they leave a comment on your blog without having to fill out a separate form.
In addition, the plugin now comes with a dashboard pane that gives you access to information about how well it is working for you.
This is great, as it’s easy to overlook the typical opt-in form on a site, and the people subscribing to a list in this way are engaged and interested in your content.
