Plivo

Plivo is a cloud communications platform that helps you add voice and SMS capabilities to your applications and business processes. You can set up custom voice greetings and interactive menus that guide callers through options, automate message delivery via SMS or phone calls, store and organise contact details with custom fields and tags, and design communication workflows that handle incoming calls and messages according to your rules. The platform is designed for developers and businesses who want telephony capabilities without needing to understand telecom infrastructure. You can build fairly complex call flows using Plivo's visual workflow tools, which can route calls, record interactions, trigger outbound messages, and integrate with your other systems through webhooks. Plivo offers a freemium model, so you can test the platform free before paying for higher volumes. It works well for services like appointment reminders, customer support automation, two-factor authentication, survey platforms, and any business that sends regular SMS or voice messages to customers.
