Check Data Usage and Sender Quota Limit

If sender quotas are enabled, you can check your sender quota limit and the amount of data you've sent in your personal preferences.

Click the profile icon in the banner and select Account from the drop-down menu. Go to Sender Quota.

The page shows your remaining available data in the current rolling period and the quota limit set for your account. When the remaining available data drops to zero, you cannot send packages until the rolling period expires and your available data is reset.
