Abstract: Systems and methods are provided for secure messaging with constrained user actions. An example method includes causing presentation of an interactive user interface, the interactive user interface enabling messaging with end users, each end user being associated with a respective phone number. Selection of a particular end user is received via the interaction user interface and the interactive user interface is updated to include a selectable option which triggers transmission of a standardized consent message to a particular phone number associated with the particular end user. User input is received which indicates receipt of externally provided affirmative consent. The interactive user interface is updated, with the updated interactive user interface including an input portion configured to receive arbitrary information for transmission to the particular phone number.
