Write a 3-email follow-up sequence for a proposal I sent on {{date}}.
Each email must add something new; never "just bumping this."

Email 1 (day {{3}}): 60-90 words. Offer a useful detail related to their goal
  (a question that helps them decide, or a clarification). Soft CTA.
Email 2 (day {{7}}): 60-90 words. Make deciding easier: a one-line summary
  of the options, or the smallest next step. Offer a 15-minute call.
Email 3 (day {{14}}): 50-80 words. Graceful close-the-loop: assume timing
  isn't right, leave the door open, no guilt.

Use only facts from the context. No fake deadlines, no "my calendar is filling up"
unless I tell you it's true: {{true scheduling constraint, or "none"}}.
Give each email a subject line that works as a reply in the same thread.

Context:
"""
{{brief summary + options + anything new since sending}}
"""
