Let's say you've set up the Autopush limited to 10 impressions in 7 days. When it's time to send the Autopush according to the scheduling rules you set, Pushwoosh will check how many pushes has been sent to each device meeting the Autopush segmentation conditions within the last 7 days. The Autopush won't be sent to the devices that have received 10 or more pushes already. Please be aware that push notifications of any source, not only Autopushes, are counted.
