Question: Is there a platform that allows me to send private voice messages to multiple recipients and track their reactions?

If you need a service to send private voice messages to a group of people and keep track of how they respond, Async is a good choice. Async lets people share smart voice memos with anyone using shareable links. The memos are interactive, listenable, readable as transcripts and can be annotated with replies that include a timestamp. The service also offers private broadcasts and AI summaries, so it's a good fit for founders, CEOs, investors, coaches and other professionals who want to get more out of their communication.

Another good option is Sendbird, an all-purpose communications API service that handles chat, AI chatbots, SMS, WhatsApp, voice and video. Sendbird offers very abstracted APIs, software developer kits and UI kits that let developers create their own messaging experience. It can handle group chat, AI-powered conversations and message translation, which could be useful for gauging reactions with targeted messages.

If you're interested in AI-powered voice communication, VoiceDrop.ai brings a different approach. The service lets you send unlimited ringless voicemail drops with personalized messages using its AI VoiceClone technology. It integrates with common CRM systems and offers analytics to track how well a campaign is doing, so it's good for businesses trying to boost their voicemail marketing.
