Creating new business leads when marketing to contacts
I'm doing mailouts to contacts, with alerts sent to our sales team when they reach a certain score. Although there is a 'lead source' in the contact database in SFDC which I can set to 'email marketing' for example, I don't know of any way to automate the generation of a 'new business lead' or even an opportunity in SFDC from Marketo, so currently I'm relying on the sales team to go from the contact, to the related account and manually create a new opportunity, where they have to manually tag it with the right lead source. Am I missing something?
