Hi andrewd10864294​Yes you can send Push notifications through a campaign. You would need to setup a Mobile Application channel and you would need to integrate that with SDK. And then you can use Android and Ios delivery setups to send push notifications.Read for the steps - Setting up mobile app channel https://docs.campaign.adobe.com/doc/AC/en/DLV_Sending_push_notifications_Creating_notifications.htmlThanksDeepak

Hi RaulOcana​ Don't think we have OOO functionality for this. Best way to know about delivery start is sending a seed to yourself. So when delivery starts at scheduled time, you will also get the same email in your inbox.ThanksDeepak

Hi Nidhi, Autopk="true" is used to declare a unique key. Read below - autopk (boolean): if this option is activated (autopk="true"), a unique key will be automatically defined. This option may only be used on the main element of the schema. Warning, Adobe Campaign only guarantees that the key generated is unique. It is not guaranteed that the key values are consecutive and incremental. ThanksDeepak

Hi mahmudshah2905​There is no way by which you will be notified if Error page is displayed to the customer. Customer can be re-directed to error in case they are not the subscribers. But you will be only able to track their clicks on that page, and also redirected links in some cases. But no notification will be sent to you.ThanksDeepak
