Every Monday at 10:00, find customers without an active plan who used a day pass or booked a desk or room 3 or more times in the last 30 days.
Email each of them a friendly invitation to become a member. Mention how often they visited and what they spent last month, compare it with the plans that would fit them, and explain how to sign up in the app.
Skip anyone we emailed about plans in the last 60 days and anyone who canceled a plan in the last 90 days. Write in the customer's language and keep it under 150 words.
