Baby shower invites

I sent out invites to my shower mid May for my shower July 22. I set a rsvp date for July 1, I sent out a group text to people who haven’t rsvped yet to message me and let me know if they are coming. If I have people who don’t respond, do I let it go and not try and reach out again or do I sent separate text messages out when the day gets closer? Like obviously they have to interest in coming if they haven’t rsvped on their own or responded to a text message I sent 1-2 days ago?
