A question came up recently about email versus mail merge templates - when do you use one over the other? What are the advantages and disadvantages of each? In response, I put together a quick grid comparison of different features:
Insert merge fields
Are available to send in bulk
Preview before sending in bulk
Edit before sending in bulk
Place content in the body of an email
Respect do not contact rules
Create personal or organization-wide template
Can be used in workflow
Can be created globally for use across multiple entities
Can be created for custom entities
Requires the Outlook client to create template
Enjoy.
