# Step 4: When

In the **Start Sending Messages** section, choose when to send your email campaign:

* **Now:** Send your emails immediately.
* **Delivery Speed:**
  * **Send Fast:** Sends the notification to all users at once.
  * **Send in Packages:** For large audiences, send notifications in smaller batches. Select the package size, and the system will send notifications batch-by-batch until all users receive them. This can improve delivery efficiency and reduce server load.
