In a previous post I spoke about the differences between Mailerlite and Mailchimp. Although Mailchimp has been more popular for some time, the team at Mailerlite may quickly surpass Mailchimp on features.
One of the main differences, is the quality landing pages that Mailerlite offers. While Mailchimp gives many ways to connect natively to other apps, there is no need with Mailerlite when you are able to send them to a landing page that looks professional.
One warning is that you mist have a live website so the Mailerlite team can approve your account, but I talk about how to get around that in the video as well.
Check out what I mean in the video.
