We have released the first part of our Salesforce.com integration, a section within JangoMail that allows you to pull in your Leads/Contacts in real-time from your Salesforce.com account, and then send an email campaign to your Leads/Contacts, or a subset of Leads/Contacts.
To use this feature, your Salesforce.com account must allow API access. Salesforce.com Enterprise and Unlimited edition accounts have API access turned on by default, but API access is also available for Professional edition a la carte.
From JangoMail, click the Extract from My Database tab, and then click on the Connect to Salesforce.com button.
