In-app messages are messages that are displayed within an app on a user’s device. These messages can be used for a variety of purposes, such as promoting a new feature or offering a special deal to users. In-app message builders are tools or platforms that allow app developers or marketers to create and manage in-app messages.

In-app message builders typically provide a range of features and options for designing and customizing in-app messages. This may include the ability to add text, images, and other media to the message, as well as customize the appearance and layout of the message. Some in-app message builders may also offer options for targeting and segmenting users, as well as tracking and analyzing the effectiveness of in-app messages.

In-app message builders can be used in a variety of contexts, such as mobile apps, web apps, and even desktop apps. They can be integrated into an app through APIs or SDKs, or they may be provided as part of a larger marketing or customer engagement platform.
