A new update to the site. You can now add your email provider (I use Mailerlite) to your site so when people register they can choose to sign up and join your email list. They also get an opportunity after checkout as well.
I will make a video on how to use it soon and add documentation. So now you can use a call to action form and add your newsletter sign up on a page and you can capture sign ups when people register and after buying a product.
