Write a Course Promo Email to a Warm Audience

Act as a course launch email and warm audience conversion specialist. I want to write a promotional email for [COURSE_NAME] to send to my warm audience of [AUDIENCE_SIZE] who already know me through [HOW_THEY_KNOW_ME] (newsletter, LinkedIn, past clients). The course is [COURSE_SUMMARY] at [PRICE_POINT]. Write a warm audience promo email covering: a subject line that feels personal rather than promotional, an opening that references the shared history with the audience, the course introduced through the transformation story of one ideal student, the enrolment details with a specific deadline, a personal invitation rather than a generic CTA, and a P.S. line for skim readers.
