We are planning on sending out save the dates soon for our 10-10-2020 wedding (we already have them and are not planning on wasting all of them). We have an A list and a B list now due to the virus; the A list is our family and wedding party and B list is the rest of our friends. We are definitely going to send them out to our A list. We are thinking we might being able to host all 75 of our guests so we'd like to send save the dates to our B list as well. We realize that anything can happen though. If we can't have our B list, we were considering getting a video of our ceremony to them and celebrating with them at a later, safer date.
We are likely going to include an insert acknowledging COVID-19 and making sure the line of communication is open. We are thinking that some people might use that as an opportunity to go ahead and decline if they don't feel comfortable.
Even if we were to send save the dates to only A now and wait until maybe July to see if we should send them to B, how would we handle things if we end up having to cut the list closer to our wedding date? If you were my guest, would you think it looks better to have a formal announcement mailed to you or would you rather have super quick communication via text/call/email?
