Advice needed, Best practices for SMS prelanders + recommended tools/platforms?

Hi everyone!
I’m planning SMS retargeting campaigns for iGaming (Poland, France, Netherlands, UK, Germany) — around 50 sendouts per day to players who’ve been active before.
I want to use a prelander instead of sending the link straight to the platform. I’ve done email prelanders before but want to optimize for SMS.
My questions:

1. What makes a good prelanding page for SMS traffic (especially for casino/gambling offers)?
   • What elements should it include?
   • What tone/format converts best?
   • Examples of structures that have worked?
2. Which platforms/tools do you recommend for building prelanders quickly and reliably?
   • Especially tools that work well with SMS flows / mobile
   • Any page builders, templates, or hosts you prefer?
3. Do you personally use any specific templates or frameworks that consistently perform well for this type of traffic?
4. Any other tips for improving conversions before users hit the offer (e.g. content angles, personalization, incentives)
   Thanks in advance!

Short mobile first prelanders work best for SMS traffic because people click fast and leave fast. One clear CTA and simple bonus angle usually converts better than long fake story pages now. Biggest mistake is heavy pages with too many redirects because carriers and filters hate that.
