There are many different etiquette rules out there when it comes to properly addressing wedding invitation envelopes. We will list out some etiquette information here, but at the end of the day the most important thing to keep in mind is that this is your wedding day, and you get to decide what works for you and your guests!
The History of Double Envelopes
Back when wedding invitations were delivered by hand, double envelopes were used. When the invitation was delivered to your guest, it was removed from the outer envelope, which contained the guest’s address, and presented to them with just the inner envelope. Since the address was no longer needed, the inner envelope just contained the guest’s name. In keeping with tradition, some invitations are still mailed with double envelopes - the outer containing the guest’s name and address and the inner with just the name.
When using double envelopes, the return address goes on the outer envelope. The inner envelope includes the liner and remains unsealed.
When addressing invitations, the formal way to address your guests is by using their proper titles, followed by the address fully spelled out - no abbreviations.
