It's very easy to use within our SAP system. The support is great too! Very flexible and customizable. I like that they have a lot of different templates available. For example, we are using it for sending out general emails as well as emails with attachments. For now, there isn't anything I dislike about this product. If I had any suggestions, it would be to make it possible to add additional fields such as a date field or a time field. We're trying to streamline our internal communications process. This software has been extremely helpful in doing so.
