Send bulk SMS from a list of numbers

1. Open Bulk SMS.
2. Upload a CSV or Excel file, or paste the numbers. If your file has columns, choose the one that holds the phone numbers.
3. We check the list and show how many numbers are ready, how many need fixing, how many are repeated and how many we cannot reach. Repeats are removed so nobody gets the same message twice.
4. Write your message. The counter shows how many characters it has and how many parts it will be billed as.
5. Check the total cost, then press Send.

• A normal message is 160 characters. A longer one is sent in parts of 153. Messages with emoji or special characters use 70 and 67. Each part is billed once for each number.
• Your message does not have to include a code. Anything you want to say is fine.
• You need enough balance. Top up here if you are short.

Developers can send single or bulk messages through the SMS API.
