I like that it is customizable, easy to use with great customer service! Nothing so far - but there's nothing wrong either just everything works perfectly for us right now!! This software has made managing our business easier than ever before because we can see all of messages in one place without having multiple accounts or tracking programs individually- its wonderful. ! Thank you very much as this was easily my favorite thing about them. They have saved me SO MUCH TIME when i had no idea how long some emails were taking from someone else being out sick etc.- they also give free support which helps too I like that it's very easy to use, as well has being able touse for both personal & business needs! It can be used in many different ways - from sending out mass emails or announcements through our website etc., but my favorite is using this software with clients who are unable/unwillingto send me email messages via their own accounts (and they have no idea why!). This makes things so much easier when trying resolve issues without having them know what you're doing behind there backs!!
