Brevo bulk SMS setup for Ultra SMS

Steps

1. Sign in to Brevo and open SMTP & API, then API Keys.
2. Create a key and copy it.
3. Make sure your account has SMS credits.
4. In Ultra SMS open the Gateways tab, click Add gateway, choose Brevo (transactional SMS), and paste the key and set the sender.
5. Send a test message to your own phone before you start a campaign.

Good to know

• Text containing a stop code is treated by Brevo as marketing.
• There is no read-only account check for this gateway, so Test credentials cannot verify the login. Send a test SMS to your own number instead.
• This gateway has no delivery look-up in Ultra SMS, so its messages show as Sent, not Delivered. Check the gateway's own dashboard or reports for final delivery.

Before you send through Brevo

Brevo charges per message segment at its own rates, which depend on the destination country. Check that your sender is allowed in each country you text. Business traffic to the USA normally needs A2P 10DLC registration or a verified toll-free number, and India needs DLT registration. Use Test credentials first, then send one real test to your own phone.

Dashboards change their menus from time to time; if a label differs, look for the API keys or developer section. Stuck? See the Ultra SMS troubleshooting table, the Ultra SMS user guide, or contact us.
