JangoMail has corrected field misalignment that was occurring when sending to campaigns with members from both leads and contacts.
The error resulted in problems with personalization fields not properly matching during sending.
This is now fixed. As a result of the change we have made, some personalization syntax has changed slightly. Before, when you pulled from Contacts, Leads, or Campaigns, the fieldnames would have "Contact." or "Lead." prefixing the actual field's name. So "Contact.FirstName" and "Contact.LastName" for example were the field names. As a part of this fix, the field names are no longer prefixed by the table name. These would simply now be "FirstName" and "LastName" alone.
