One Call Now
What it is
One Call Now sends group messages by text, phone, email, and app alert for organizations that need to reach contacts in different ways. Messages can use multiple languages and formats, and contacts can be imported from CSV or spreadsheet files or integrated from software such as Salesforce or Outlook. Users can create unlimited dynamic groups, from one contact to thousands, and personalize messages. Senders can deliver alerts immediately or schedule them, then view real-time reports on who received each message and when. For automated calls, typed text can be converted to voice, and a saved audio library is also available. Text recipients can respond, with replies tracked in the mobile app. One Call Now is available on web, Android, and iOS; its mobile apps are intended for authorized senders. The paid service offers a seven-day trial with 25 credits and no credit card required. Trial access ends unless the customer signs up for a paid account. Listed annual plans require a contract; actual costs depend on usage, group size, and industry.
