I like that it's very customizable. The ability to have a "Send" button right on my website for people to use when they are there. I also like that I can see all of my sent emails at once. It sometimes takes a few minutes for emails to go through. Sometimes it doesn't send them to my inbox but instead puts them in a folder. If you want an email service provider that will help you send out emails for you then this is the best one available. We've been able to take on more clients than we would if we had to do it ourselves. I love how it provides great customer service and also helps me monitor my social media pages to make sure they're up to date. There are many social sites out there so this makes keeping tabs easier than ever! Nothing really. Just keep using it as you would any other email provider. It does its job well - which is what we need at present time. We have seen an increase since moving to this type of product from another competitor.
