It helps me validate emails for my list so that I can send out campaigns with confidence, knowing they are being delivered correctly! The platform is easy-to use as well has great customer service if you need help at any point along your journey of using their services (which we've never needed!). There's nothing much about this software which i dislike - it does exactly what its supposed too do without fail or error!! We have used MailChimp before but were not happy because there was no way our clients could see who had opened an e mail from us unless someone clicked through directly into another page where all details would be displayed etc.. This solves those problems by allowing people right away when opening up one particular campaign whether anyone else will open them first/second time round meaning more sales / conversions.
