We've had great success using HubSpot. It's very simple to use and has allowed us to take great strides in automating our marketing activities. We can easily keep track of prospect and customer info and the deal tracker gives us fast access to the important information. The support programme is great and there is a wealth of knowledge and tips to be found in the help forums and help centre.It's been a vital tool in helping us grow - I really can't recommend HubSpot enough.
