# 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.

* Verify your campaign information carefully.
* Test the message on your device to ensure everything looks and works as expected.
* When ready, click **Send** to launch your email campaign.\
  After sending, monitor your campaign performance via the Reports.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://user.netmera.com/netmera-user-guide/omnichannel-engagement/email/send-email-campaign/step-4-when.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
