What CallMultiplier is
CallMultiplier is a web-based service for sending voice broadcasts and text messages to groups. The maker says campaigns can reach 50 to 50,000 contacts. Voice messages can be scheduled, delivered to voicemail, built from uploaded audio and set up for touch-tone poll responses. Campaigns can show the sender's phone number or a CallMultiplier Message Playback Number. Contact uploads, subgroups, multiple users and recurring sends help organize campaigns, with real-time delivery reports. Texts can contain images and reach 1,600 characters, though replies go only to the account holder. Its API can connect to existing software to sync member lists or let people opt in through a web form or app. The service says it delivers messages across the United States and Canada. The maker prohibits unsolicited, telemarketing or solicitation messages and assigns users responsibility for following applicable law. The first purchase has a 30-day money-back guarantee, and the company says phone support is available 24/7/365.
