# What do you need to send an SMS campaign in Sarbacane?

License, credits, numbers, consent, message: check the five requirements before sending your SMS campaign.

To send an SMS campaign with Sarbacane Campaigns, you need five things: a license, enough SMS credits, mobile phone numbers, your recipients’ consent to SMS marketing, and a message with no blocking characters.

## Prerequisites

-   **A Sarbacane Campaigns license.**
    
-   **Sufficient SMS credits.** Without credits, you can create a campaign but not send it. An SMS costs 1 to 3 credits per recipient, depending on its length.
