At DigitalOcean, text messaging is used for both security and internal communication purposes, with Twilio providing an intuitive API that enabled the company to quickly integrate and expand its usage of SMS throughout their applications. The platform has helped the company's customer base by efficiently handling high volumes of SMS traffic, delivering messages quickly and reliably, and supporting global customers. DigitalOcean also uses SMS for identity verification and anti-fraud measures, making it an increasingly important channel in their future development plans.
