A simple mail merge merges a data file with one form letter. Use this when sending the same letter to all constituents in a mailing.



A conditional mail merge merges a data file with multiple form letters based on a condition, normally the letter code. Use this when sending different letters to constituents in a mailing.  For example, when sending donor acknowledgement letters, constituents who give under $100 receive one thank you letter and those that give $100 or more receive another.  The conditional mail merge allows you to send different letters based on a field in the merge such as the Letter Code or Gift Amount fields.
