If you reach your account’s impressions limit in any given month, you campaigns will be paused and your account will be locked until the start of the next month, at which point the impression counter resets to zero and your account will automatically unlock and your campaigns will be reactivated.

Your account dashboard will always show the number of impressions remaining for the current period so you’ll have plenty of notice to upgrade if it looks like you’ll run out.  We will also send out some advance warning emails at 70% and 90% of your impression limit.
