Find Sequences and invite people who have not responded for an event

Open Events → Events → select your event → Edit Event → Sequences.

Open the event’s administrator editing area and choose Sequences, then create an Invitation with the intended invitation audience. Invitation creation applies an event RSVP exclusion; do not confuse no response with an explicit RSVP No. Review the resulting recipient list. The school must have event sequences enabled; on events using Setup capabilities, Sequences must also be enabled in the event’s Setup settings.
