Once your intake answers are saved, ask Site Builder for a plan only. Read the proposed invitation, reminder and follow-up, including placeholders and decision owners. Here, the reminder needs a correction: it is for registered attendees and should cover logistics, not another registration pitch. Request that change on the same task and keep drafting off. Review the revised plan, check the retained placeholders, and confirm where it is stored. This plan is text in the task thread. It still needs a separate decision before drafting begins.
