I like how easy it was to set up my template and then customize as needed. It's also very flexible in terms of what you can do with your templates (I've used them for event invitations, newsletter subscription signups, etc.). A few things are not intuitive - but this could just be me trying something out! There are some other programs that are more expensive or have better features/functionality, so make sure you're comparing apples to apples before signing up. We were able to create beautiful templates quickly using InxMail. Our clients love having an option to subscribe to our monthly eNewsletters through social media instead of waiting until we send another one out.
