Onboard Free UserAbout this email
This email is a friendly and concise trial expiration reminder from Buffer aimed at encouraging users to select a subscription plan before their trial ends. It structurally combines a personalized greeting, a clear call-to-action button for selecting a plan, and reassurance about the automatic downgrade to a free plan if no payment details are provided. The tone is warm, supportive, and customer-centric, reinforced by testimonials and an open invitation for direct support responses.
Buffer journey
Why this works
**Why this works.** The subject line leads with urgency (a countdown) rather than a feature or benefit, which makes the reader feel the time-scarcity before they open it, priming them to act inside the email instead of delaying the decision. The pattern here is "lead with scarcity, not value"; you can lift it for any trial expiration email where you want users to upgrade before they procrastinate the choice away.
