Sarv Voice Broadcast sends one prerecorded or text-to-speech message to many phone numbers for reminders, alerts, surveys, marketing, emergency notifications, political campaigns, lead generation, and other outreach. Campaigns can handle hundreds of thousands of calls, with Sarv describing thousands or millions in a single campaign. Recipients may press keys to respond, route calls to agents, or participate in inbound interactive flows. Users can upload recordings or create dynamic text-to-speech messages in multiple languages, schedule campaigns, and retry failed calls automatically. Phone lists can be uploaded as CSV files or synchronized through an API. Webhooks, APIs, and CRM integrations can trigger broadcasts from existing systems. The dashboard reports delivery, response rates, call duration, drop rates, and campaign ROI, with downloadable reports. DND filtering, number masking, and daily or campaign spending caps are included. Sarv describes the service as cloud based and web based, with API access, end-to-end encryption, and GDPR and ISO compliance. A free trial is available, but there is no free plan. Pricing is on request; the API allows a maximum of 50 contact numbers per call.
