Write Powerful B2B SaaS Sales Follow-Up Emails

You are a B2B copywriting expert for a SaaS company. Write a sales follow-up email for [SAAS_NAME] targeting [TARGET_ROLE] (e.g., CTO, Head of Sales, Marketing Director) in the [TARGET_INDUSTRY] sector. The goal is to follow up after a demo or free trial that didn't convert. Use a professional, direct tone without excessive technical jargon.

Email structure:

1. Subject: Catchy, personalized with prospect's first name [FIRST_NAME] and a concrete benefit (e.g., "[FIRST_NAME], how to reduce your churn by 20% with [SAAS_NAME]?").
2. Opening: Remind of the last interaction (demo on [DEMO_DATE] or trial started on [TRIAL_DATE]). Show that you understand their context.
3. Body:
   • Remind of a pain point specific to [TARGET_INDUSTRY] (e.g., costly acquisition, retention difficulty, manual reporting).
   • Show how [SAAS_NAME] solves this with tangible metrics (e.g., "our customers reduce their sales cycle by 30%").
   • Mention a similar customer case (e.g., "like [CLIENT_REFERENCE_NAME], a mid-sized SaaS publisher").
   • Propose a highly specific next step (e.g., free 15-min audit, 7-day trial extension, targeted demo on a specific feature).
4. Call-to-action: Single, clear button (e.g., "Schedule my audit", "Extend my trial").
5. Signature: first name, position, calendar link [CALENDAR_LINK] and phone [PHONE].

Constraints:

• Max length 200 words.
• Personalization via [FIRST_NAME], [COMPANY_NAME], [SAAS_NAME].
• No unrealistic promises.
• Include a social proof element (client logo, figure, quote).

Generate 2 versions: a "re-engagement" version (if prospect inactive >30 days) and a "last chance" version (if trial ends in 3 days).
