How effective is Event Text Messaging in boosting attendance and engagement at events?

I'm considering using event text messaging to improve attendance and engagement at my upcoming events. I've heard that SMS reminders and updates can be more immediate and impactful compared to emails or social media posts. For those who have used text messaging for event management, how effective has it been in boosting attendance? What kinds of messages (reminders, updates, last-minute changes, etc.) work best? Are there any best practices for timing and content to maximize engagement? Also, are there any tools or services you recommend for managing these text campaigns? Your insights and experiences would be greatly appreciated. Thanks!
