Bulk SMS that reaches your customers in seconds.
Send promotional, transactional and OTP messages from one platform. Plan campaigns, filter DND numbers and connect your own software through API or SMPP, with a team that helps you from setup onward.
What is a bulk SMS service?
A bulk SMS service lets a business send the same text message to many people at once. Each person receives it as a private message, not a group chat, so replies and opt-outs stay individual.
Businesses use it for offers, order and delivery updates, appointment reminders, payment alerts, event notices and login codes. Unlike a phone's messaging app, a bulk SMS platform is built for large lists, scheduled sending, delivery reports and compliance controls.
Bulk SMS vs. texting from a phone
Why businesses move from phone apps to a dedicated service.

| Opt-outs | Handled by hand | DND filtering for campaigns |
| Scheduling | Send it yourself, live | Plan campaigns ahead |
| Reporting | None | Delivery reports |
| Software connection | Not possible | API and SMPP |
