Announcing elopement ideas??

I’m looking for ideas on how to announce we “eloped” to family and friends (on and off social media!) We had less than 15 guests and it was immediate family and very small. I know some people are going to feel hurt that they weren’t invited so I hate to post on social media saying we eloped first off because I don’t think social media is the way to find out for close family and friends! I was thinking of mailing out a few cards with some pictures our photographer took first to the people I’d rather not find out on social media and then after they receive them post it in social media. We really wanted to do a casual reception type dinner at our house and invite everyone but I know that’d be hard because of COVID and some family members wouldn’t be comfortable with coming. Ideas??
