Oklahoma City, Oklahoma, United States
What it 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 and deliver throughout the United States and Canada. Voice campaigns can be scheduled, sent to voicemail, built from uploaded audio, or set up to collect touch-tone poll responses. Campaigns can display the sender’s number or a CallMultiplier Message Playback Number. Contact uploads, subgroups, multiple users, recurring campaigns, and real-time delivery reports support campaign management. Texts can include images and reach 1,600 characters, while 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. Plans start at $7.99 a month for up to 25 members, with unlimited standard texts and calls, voice messages up to two minutes, and texts up to 320 characters. The maker prohibits unsolicited, telemarketing, and solicitation messages, and users are responsible for following applicable law. The company offers a 30-day money-back guarantee on the first purchase and says phone support is available 24/7/365.
