Multi-objective electronic communication frequency optimization

A system comprising:

• one or more processors;
• and
• one or more computer storage media storing computer-executable instructions that, when executed by the one or more processors, implement a method comprising:
• receiving recipient data for a recipient of electronic communications, the recipient data indicating response behavior associated with received electronic communications;
• determining an opt-out probability for the recipient by applying a first model on the received recipient data;
• and
• determining a frequency cap for the recipient, the frequency cap determined, via a second model, based on the opt-out probability compared to a recommended electronic communication frequency for the recipient.

One or more non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method for determining use of a delivery schedule, the method comprising:

• means for identifying a group of electronic communication recipients associated with a set of historical responses to received electronic communications;
• means for determining a delivery schedule for the group of electronic communication recipients using a frequency optimizer model that identifies frequency optimization for the group of electronic communication recipients and each of the electronic communication recipients;
• and
• means for determining to use the delivery schedule based on user engagement with electronic communication delivered via the delivery schedule being greater compared to user engagement with electronic communication delivered via a random schedule.
