Has anyone used Cordially Wed or any similar type of products for mass texting for weddings?

I’m having a multi day cultural wedding with events at various venues. We have guests split in 2 hotels, some staying at the hotel with events and some nearby. To avoid confusion, I wanted to provide updates about timings, venues etc to our guest for their ease. I didn’t want to use my phone or make group chats cause I know how they get, people would start blowing up the group chats and it can get annoying.

So I started exploring mass texting services cause it would remove me from the equation while also helping me text everyone. I was wondering if anyone has had experience with Cordially Wed as I keep seeing it on social media? Or if there’s anything else you recommend/ how did you manage a similar situation to me?

Appreciate the help!
