We have a constituent organization that provided specific mailing instructions regarding a recent pledge. The business's owner stated that all mail regarding the pledge should be addressed to him at the business and marked “Confidential." These mailings will include pledge reminders, thank-you letters, and year-end tax receipts.
What is a good practice to ensure all these mailings are marked as confidential? If the constituent was an individual, I would probably customize the primary addressee format, but I don't think that's possible for an organization. The owner also donates personally, so we can't change his addressee format without affecting personal mailings as well.
Any help would be greatly appreciated. Thanks!
