Schedule your content on X

In Metricool, you can easily schedule your content to go out exactly when you want.
Connecting X (Twitter) in Metricool is a paid add-on and only available in Starter plans or higher. Check all the details here.

💡 Use the Best Time to Post feature to know when your audience is most active and check the image and video requirements to make sure everything looks perfect.

✏️ Key Points
