Most of these concepts apply to email and SMS messages. In Mapp Engage, you find the related functions in the main menu under *Messages*, for example *Messages > Prepared Messages*, *Messages > Outbox*, and *Messages > Limitations*. For creating a message in a specific channel, see [Channels](/v1/docs/system-basics-channels).
