# Activate your first Segment

Here are the steps involved in the activation of the segment (via [Reverse ETL](https://www.dinmo.com/reverse-etl/) process) you created in the last section:

1. Go to the "Segment" section of the app, and click on your segment\ <br>

2. On the upper right, click on "Activate".<br>
3. Tick the activation targets to which you want your segment to be sent. If you tick multiple activation targets, your segment will be sent to all of chosen platforms at once. The sync configuration will be the one defined by default in the activation target. If you wish to change it, click on "Advanced".\
   \
   If no Activation Target is shown, it means that no activation target has been configured for the parent entity of the selected segment. In that case, or if no appropriate activation target is shown, [create a new one](https://docs.dinmo.io/guides/get-started-with-dinmo/create-and-activate-segments-on-dinmo/broken-reference). You cannot activate a segment without an activation target.\ <br>

4. Hit "Activate".

Congratulations, you just created your first sync! You will soon be able to visualize your segment on your destination platform.

Note that for some platforms, it is required to wait 24 to 48h before the sync is complete on their side.
