I like how easy it is to use, you can create autoresponders that are customized for each individual contact or list of contacts without having to do any work yourself. It's great if you have a lot of clients/contacts because then all your messages will be saved so that they're not lost when someone changes email addresses. Sometimes it takes a few days before my emails go out after sending them from the editor but that has nothing to do with iContacts. If you need an auto responder service that works well and saves time, this one should definitely be considered. We've been able to send mass emails to our entire customer base almost immediately upon their signing up with us which helps keep everyone informed about upcoming events and important news.
