I know Mike from SMS Bump is on Shopify slack channel. Or you can just opt to email them directly through their support page. email@example.com. I'm sure they would be happy to help you.
Hi Kyle, I am not familiar with that app but I am the Co-Founder of "Text Funnels" which was just launched on the shopify app store 2 days ago. We've used the app privately for over a year so it is tested and proven. We are currently working one on one with new stores who need help and I am happy to help you as well. Let me know if you have interest and we can schedule a meeting to get you setup and maximizing our features.
Hey and thanks for reaching out.
I work at SMSBump. We offer 24/7 support + Support on weekends so you can always reach either by mail, at messenger or intercom:
