# Instructions for sending an SMS campaign with the Booster option
1. Create your campaign [according to the instructions](https://docs.messageflow.com/sms/sms-campaigns/campaigns/creating-sms-campaign)
1. Use **tracked links** in your message
2. Schedule the campaign for an audience group (not individual numbers) — this is required for Booster to work
2. In the summary step, **enable Booster** by toggling the switch and filling in the required fields:
1. Sender ID
2. Message content
3. Personalization
4. Tracked links
{% hint style="warning" %}
The same rules apply for message length, billing, and use of special characters (e.g., Polish letters) as in the main campaign. Message throughput is set by default and cannot be changed.
{% endhint %}
Set the Booster conditions:
* Choose the sending time (between 2 hours and 7 days after the main campaign)
* Select the option “to users who didn’t click”
4\. Test your campaign using the “**Send Booster test**” button.
5\. Finally, **Save** your campaign or **Save and Send**.
{% hint style="warning" %}
Both the main campaign and Booster can be edited until the main campaign is launched (i.e., as long as the status is “edited” or “scheduled”). Booster campaigns can be cancelled anytime before they start.
{% endhint %}
{% hint style="success" %}
