Save-the-Date for Pastor, and Addressing Save-the-Dates

I think sending save the date to your pastor would be a nice gesture but as with any guest, not required. Send one if you have one to spare.

Include the guest on the invitation address and make every effort to get the guest's name. This will make things so much easier for you and your guests so they know who exactly is invited. It also prevents situations where, for example, someone's husband can't come so they bring their 3 year old hyperactive kid or their insane drunken friend you don't like. ETA that's for significant others, whose names should always appear on invites. For single guests, if you don't know who they are currently dating, you can put "and guest".

No to the STD to the pastor. You don't "have to." His STD should be the contract.

I think if a guest is truly single, then you're just addressing it to that guest. I could be wrong but I always default to @mna on these things.

If they are in a relationship, address it to both parties: Samantha Smith & John Judge or Mr. & Mrs. Smith.

Just wanted to point that out because people get plus ones and SO's confused.

I didn't invite plus ones to my wedding unless I knew the person was in a serious relationship or for our siblings. For the ones in a relationship, I asked for their names.

Ok. A few of our guests have SO's so I will make sure to use their names. Many do not, so for them I will just use the "& Guest". After giving it more thought I've decided it is appropriate to use it. This way they can anticipate being able to invite a guest. That makes the most sense. Thanks for your thoughts!
