Email Letterhead ID
Specifies which Salesforce email letterhead is used in conjunction with a Conga Email Template. In Conga Composer Release 7, Conga Email Templates used the Conga Email Staging object which only allowed the use of one Salesforce email letterhead. With Release 8, the Conga Email Staging object has been deprecated and email letterheads are no longer required; however, if you wish to use a Salesforce email letterhead, you can specify it using this parameter.
