Bulk SMS API
Send one message to many numbers in one request.
What it is
When a message needs to reach a whole list, send it in one request instead of thousands. Each number gets its own message ID so you can track every delivery separately.
How it works
Collect your numbers
Put the recipients in a list. Duplicates are removed and charged once.
Send one request
Send the list and your message to the bulk address.
Track each message
The answer lists a message ID for every number.
Good for

- School and church notices
- Service interruption alerts
- Sending to a customer list stored in your database
What you get
- Many recipients per request
- A separate message ID for each number
- Cost known before and after sending
- Daily limits to protect your account
