What our clients say

  • "My clients book their yoga classes with me in advance and using the Cosmic SMS service has given my business an extra dimension to the experience I provide. The ability to schedule messages enables me to better organise my workload so I can optimise the time I spend on administrative tasks and spend more time teaching classes and creating useful content to help people. My clients have often told me how much they appreciate their class reminders."

    All You Yoga

  • "Cosmic SMS provides us with a dedicated SMS number for receiving messages that we use for Q&A sessions, voting and general feedback. Received messages are then typically displayed in real time to large split screen displays at the venues. The Cosmic SMS application also has very useful SMS auto-reply and auto-subscribe options. The service works really well for us, we would definitely recommend!"


  • "We use the Cosmic SMS service to keep in contact with our Contract Egg Producer base, this is an important contact method as most people have a mobile phone, but not all have a computer and email, so text messaging important information and keeping them updated is of great value to us and more importantly provides a simple but effective service to our producers."
