amazing interface, simple to integrate with SFDC, Love the metrics and analytics- that part completely blows away the other vendors including eloqua. They understand how marketing needs to deliver business data.
Room for Improvement:
They should share best practice implementation- because there's so much variation in how you can set it up- you can do it wrong. So setting it up right the first time would be ideal. This solution also doesn't scale for the large enterprise- a huge downside for them.
This is the best marketing automation solution out there, for the ease of use, the amazing metrics, the integration to SFDC, and the price.
