I see, that was not clear in the initial message.
In the email body template file, add the following code at line 1:
the n to refer to column from the recordset, use the following:
<?php echo($RecipArray[$RecipIndex]["[yourColumnName]"]); ?>
where [yourColumnName] is the name of the column, for example:
<?php echo($RecipArray[$RecipIndex]["FullName"]); ?>
