Salesforce.com has a useful feature on Leads related to “activities”. 

Activities

related list shows you open tasks, future events, and requested meetings related to a record and its associated records. For example, if an upcoming meeting on your calendar is related to a contact, that event is displayed in the Open Activities related list of the contact and the account that the contact is related to.

Use Open Activities to:

• Create events and tasks that are automatically related to the record


• Request a meeting with a contact ( denotes a meeting request that’s emailed to a contact)


• Ask a contact for an update


• Edit, close, or delete activities on the list

Meeting requests and requests for updates can be sent to a contact, a lead, or a person account.Our call tracking software is already integrated and can create activities related to inbound phone calls for new leads.

I’m wondering if anyone has created a similar integration for Unbounce and salesforce.com for inbound leads.
