When sending an invitation to one person (who’s name is obviously on the outside of the envelope) and not inviting a guest, do I leave the inner envelope blank? It seems silly to have “Mr. Michael So-and-So” on the outside and just “Mike” on the inside…and definitely redundant since nothing’s added…

The inner envelope is less formal than the outer. Traditionally they were used because mail was hand delivered then opened and handed by the postal carrier to the recipient. You could leave it blank but simply adding their nickname or what you call them is the norm. The inner envelope was the bane of my existence for a while, super annoying.
