Number the tweets (1/3, 2/3, 3/3).\n• Alt text for the image (1–2 lines, descriptive, <120 characters).\n• Suggested first-reply (one short reply to pin under the tweet/thread, e.g., resources or link).\n• 10–12 relevant Twitter/X hashtags (high-signal, platform-appropriate — avoid over-stuffing; pick the most relevant).\n• Suggested @mentions (1–3 accounts types to mention, e.g., partner, tool, or community handles; leave as placeholders if unknown).\n• Recommended posting windows (IST) — 3 time slots ideal for engagement.\n\nA compact, professional summary section inside the email with:\n• 2–3 sentence overview of the visual\n• Bullet list of Key features (3–6 bullets)\n• Bullet list of Ideal users (2–5 bullets)\n• “Built with” list (tools/tech stack; 3–6 items)\n• Single-line CTA (e.g., “Try it”, “Request demo”, “Reply to learn more”)\n\nDesign & accessibility:\n• Use {{ $json.secure_url }} for the image src.\n• Include the alt text near the image tag (use the same alt text as in the Twitter block).\n• Max width 600px, centered content.\n• White content card on a light gray background, soft box shadow, clean spacing, readable bullets.\n• Inline CSS only (no external styles).\n• Fonts: Arial or Helvetica.\n• Email must render well in Gmail & Outlook.\n• Keep markup simple and robust: tables are allowed if needed for Outlook compatibility, but keep it clean.\n\nStyle & length rules:\n\nSubject line ≤ 60 characters.\n\nPrimary tweet and each thread tweet ≤ 280 characters (include a character count comment next to each tweet inside the email as a small, parenthetical note).\n\nHeadline: single bold line inside the email.\n\nHashtags: 10–12 total.\n\nKeep the whole email concise — one glance should tell the reader what the visual does and how to share it on X.\n\n🎯 Your response must follow this exact format — do not include code blocks or markdown:\n\nSubject: [your subject line here]\nBody: [your full HTML content here — one line or multiline]\n\nDo not return JSON. Do not use ``` or Markdown formatting."
