Systems and methods of fallback electronic communications are disclosed. A system is configured to receive a communication campaign including data identifying at least one communication channel and implement a fallback state machine having a first composite state corresponding to the at least one communication channel. An initial electronic communication is transmitted via the at least one communication channel and an initial timer having a first predetermined timeout period is implemented. When a confirmation is received prior to expiration of the initial timer, the fallback state machine transitions to a complete state. When the confirmation is not received prior to expiration of the initial timer, a first composite fallback state corresponding to a first set of fallback communication channels is implemented and a first fallback electronic communication is transmitted via the first set of fallback communication channels.
