# Organize contacts, send in bulk

Create customer groups and reach everyone with one message. Import lists from Excel or vCard - no manual typing.

Instead of sending SMS to each customer individually, you create a group and send one message to all its members. The system creates a separate SMS for each person - with their name and on their number.

Contact import supports CSV, XLSX, and vCard formats. If you have a customer database in Excel or a phone export - you can upload it in seconds.

When sending to multiple groups, the system automatically deduplicates contacts. The same customer in two groups will receive the message only once.
