For Outreach and Feedback contacts, how are the Mail Type values set?
A contact's preferred mail type for Outreach and Feedback E-mails.
NOTE: This answer only applies to Outreach/Feedback mailings and does not apply to Service messages.
When a contact record is added, either manually from the administration console or from the Data Import Wizard, the Email Format field is null by default. As a result, the contact will receive Multipart / MIME email messages until the field is explicitly set to HTML or Text.
The Email Format field can be populated through an import (contacts.ma_mail_type field) or be added to a contact workspace and set manually.
You can create a contact business rule and use Email Format Preference as a condition, but not as an action. Data Import or Workspaces rules can be alternate solutions to setting this field if needed.
For more information on rule conditions, refer to the 'Contact rulebase conditions' section in online documentation for the version your site is currently running. To access Oracle B2C Service manuals and documentation online, refer to the Documentation for Oracle B2C Service Products.
