How does the platform work?
Three simple steps stand between you and effective communication with thousands of customers at once.

Prepare your SMS or MMS content, or design an IVR voice scenario. Use variables like {Name} or {Date} to personalize every message.
Select recipients
Import your phone number list from a CSV file or use an existing database. The platform supports messaging to all Polish mobile networks and 30+ countries.
Send and monitor
Schedule your campaign for a specific time or launch it immediately. Track delivery statuses, customer replies and generate real-time reports.
