Best prompts for ChatGPT Marketing for sales emails using conversion rate optimization

I have a B2B SaaS offering: 'TeamFlow — project planning for remote teams' with current subject-line open rate 18%. Create 8 subject-line variants grouped by intent (curiosity, urgency, benefit, social proof). For each variant include: short rationale (one line), estimated open-rate uplift percentage vs baseline, and which audience segment to prioritize. Then provide a clear A/B test plan: sample size per variation (assume list size 40,000), primary metric, secondary metric, test duration, and an easy decision rule for picking a winner.

You’re writing the hero (headline + subhead) for a sales email promoting an ecommerce conversion optimization course. Create 4 headline + subhead pairs using distinct approaches: direct benefit, numbers-driven, pain-focused, and social-proof. For each pair provide: one-line rationale, a suggested CTA label, and one CRO test (what to test and why). Keep each headline <= 8 words and subhead <= 18 words.

Write 3 versions of a sales email promoting a 14-day free trial for a time tracking app: short (one-paragraph), medium (two short paragraphs + bullet points), long (detailed with case study snippet). For each version include: subject line, preview text, body copy, CTA (button label + URL placeholder), target metric (trial signups) hypothesis with expected % change vs baseline conversion (baseline = 2.2%). Also include recommended audience segment for each version.

Provide a list of recommended personalization tokens for a B2B marketing tool (tokens for first name, company name, industry, ARR, plan, last activity date, most-used feature). For each token provide: sample fallback text, one conditional sentence to include if the token exists, and one conditional sentence if it doesn't. Then produce 3 short persona-specific email snippets (SB, mid-market, enterprise) using those tokens and conditional blocks formatted so developers can paste into an email platform (use double curly braces for tokens, e.g. {{first_name}}).

Create 12 distinct CTA texts for a 'Book a demo' action for an HR software. For each CTA include: one-line explanation of the psychological trigger (scarcity, reciprocity, social proof, curiosity, clarity), recommended color/placement (header, after benefits, footer), and a one-sentence A/B test to validate it.

For a monthly subscription snack box service, create three tailored sales emails for these segments: (A) recent visitors who viewed pricing, (B) past purchasers who haven't bought in 90 days, (C) subscribers who opened last 3 emails but didn't convert to premium. For each segment produce subject, preview text, 120–180 word body copy, one CTA, best send day/time recommendation, and primary KPI to track.
