Questions about bulk sms
What is A2P SMS?
A2P (application-to-person) SMS is a message sent by a business system to a customer, such as an OTP, an alert or a reminder, rather than by one person to another.
Which countries can I send to?
Most countries worldwide. Some require a registered sender ID or template approval, and we guide you through it.
Can customers reply?
Yes, with a two-way number. Replies appear in your inbox and can trigger webhooks.
Do you have an SMS API?
Yes. Send messages and receive delivery reports and replies through our REST API and webhooks.
