What are bulk SMS and voice-message calls?
They’re the fastest way to tell many customers something at the same time. An SMS is the classic text message: it needs no internet or apps and shows up on the phone screen in seconds. A voice-message call is an automated call that plays each person a recorded message, in your voice or in a natural voice created from text.
Use them to collect payments (“your installment is due tomorrow”), remind people of appointments, let them know an order is on its way, run surveys or send promotions. Upload your customer list in Excel, personalize each person’s name, amount or date, choose when to send and see live who received it, who opened it and who replied.
Best of all, your customer can reply with a single key: pay, agree on a date or ask an advisor to call them. That reply reaches your phone system, your call center or an AI agent. Messages go out over our own network, from the mobile number we give you, and we help you comply with the schedules and rules of Colombian law.
