In-app messaging: SDKs that provide the ability to send messages to users, and potentially have chat conversations with them. See here for difference between push and in-app messages.

Deep-linking: a link that takes you to a piece on content in an app. For example, if you send a link to a specific home on AirBnB, when they click on that link, they will be taken to the home in the app as opposed to the home screen of AirBnB. See here for more details.
