Serial Mail

Serial Mail Publisher's Description:
A plug-in for the Mail application to generate serial mailings (mail merge, bulk mail) using data provided by an Address Book group. The script will process the message body of the (selected) template message and replace certain tags by their corresponding value from the Address Book for each recipient. You may use custom data by specifying your own labels in the "related names" section of the persons Address Book entry (e.g. "Assistant", "Customer number", etc.) and the script will replace the corresponding tags by the corresponding Address Book values (Example: Use the script to inform students of their score (and other stuff), which is stored in AddressBook).

The program supports almost any of the data fields of the OS X Address Book, including user defined fields. The template rules are also applied to the subject line (so you may generate custom subject lines).

Rich text emails may be created (but plain text templates are processed faster).
