What's not to like? Full tracking of individuals coming to your site, scoring to help sift the diamonds from the rough, filters to let you concentrate on high valued targets, automated scripted interactions or good old fashioned one-on-one chats. Seamless integration with the CRM, and a mobile app that actually works, and the ability to have sales, support, and any other departments you have work together to help customers. It's almost perfect.
If you have gaps in coverage, the missed chat queue is not as well refined as it should be. For instance, you can't sort by the name or email to identify duplicates, and you can't see what country they came from without clicking each entry, making dividing the queue based on location difficult.
We are a small company, so any missed interactions with customers is painful. Having SalesIQ lets us have instant contact and actively engage those who might not otherwise do anything more than check out our website.
