Data Enhancement Upper/Lower Casing Change to all upper case or upper/lower. SmartMail can make each record consistently upper case or upper/lower for applications such as mail merge laser letters. While our software will provide punctuation of standard abbreviations and maintain all caps for well-know company names, the process can result in some address elements looking awkward (Example: SOS ENTERPRISES becomes Sos Enterprises.) In sensitive cases, you may wish us to review records one-by-one to ensure accurate casing of each element. Send us your feedback.
