  • We found that associates who had the opportunity to respond to a survey about their assigned job were 37% more likely to return to a job site
  • We were able to reduce the number of resources required to manually respond to associates using Twilio Studio, so those resources could have more time to complete other tasks
  • We were able to scale the number of associates who received survey messages at least by a factor of 8 without increasing our resource demand

  • Can't support our clients with their solution
  • Lost over $3,000 in development time trying to manage their support system.
  • Training for new features was halted, in my opinion, because of their lack of support.

  • New donors - Twilio is consistently our 4th or 5th most successful donor acquisition tool
  • ROI - Whether you count the actual cash or with the startup grant, we've net somewhere between 27-700 times what we put in.
  • Engagement - we can more easily track and respond to questions visitors have in the field, and folks appreciate the prompt help

  • It helped us to send reminders of payments to our clients, this allowed the clients to be more aware of their payments and so decrease the late payment rate.
  • It helped us to send positive messages to our clients to motivate them through the pandemic.
  • It helps us to communicate with our clients that don't have internet or don't own a smartphone.

  • The gains we have achieved by using Twilio are remarkable: we have increased our ROI capacity by at least 50% since we started using the service, which raises our ROI amount by 1.
  • We hope to continue working with Twilio and that the profits will continue to increase for the next working period.
