# Testing multiple campaigns

MessageFlow enables the simultaneous verification of several campaign versions. Thanks to the bulk testing feature, you can send sample notifications from multiple projects at once without having to enter the edit mode for each one.

{% hint style="warning" %}
Important: This feature is not used for conducting automated A/B tests on your target audience (traffic splitting). Its purpose is to allow you to visually compare different creative variants on your test device (e.g., to see which graphic or title looks better) before the final dispatch.
{% endhint %}

1. Go to the **Campaigns -> Campaign lis**t tab. Click the purple **Select campaigns for testing** button located in the upper right corner of the screen.
2. Checkboxes will appear next to the campaigns on the list. Select the items you want to test.

   > Tip: You can select both draft versions (status: *Edited*) and campaigns that have already been completed (status: *Sent*) for testing.
3. After selecting the campaigns, click the **Send tests** button. A window will appear on the screen with a list of available contact groups (divided into Android and iOS).
4. Contact selection: Click on the group name to expand the list of test contacts assigned to it. Check the box next to specific individuals (or the entire group) to whom you want to send the notification.

   > *You can manage the list of test contacts in the Common settings -> Test contacts section.*
5. Click the **Send** button to immediately deliver notifications to the selected devices.
