The ability to send/receive files as both sender or recipient of the messages is very convenient.The ease-of use, lack of customization or configuration options can be discouraging at times. Our company has been using this software with success since 2009. I am confident that over time it will have all our needs met! We are able to communicate and share documents in an effortless manner without having to do extra work. It's easy to integrate into existing applications, can be run in-house or remotely with multiple users, works great for small teams within larger organisations. No real complaints here. I would strongly recommend it as it is very good value for money and provides excellent customer service. You get what you pay for at times. The price is sometimes too high for the features available. Integration with other applications - such as Salesforce.
