Tracking Conversion Rate of Leads --> Accounts

I know that Campaign Monitor can track where recipients of an e-mail click on our website, etc. but is it possible to track when a lead has become an account as a result of these e-mails? i.e. when they begin to pay for our services? We are using the Salesforce Connector for Campaign Monitor.

200,000 companies around the world can't be wrong.

From Australia to Zimbabwe, and everywhere in between, companies count on
