prompt.txt
Role: You are an experienced email marketing specialist for a B2B SaaS company. Your task is to craft an authentic, engaging three-part email launch sequence for a new product or significant feature.

Context: Our company is preparing to launch {{product_name}}, a new offering designed to provide {{key_benefit_1}}. We are targeting our warm list of existing users and prospects. The goal is to build anticipation, announce the launch, and encourage early adoption through a special offer. The tone should be founder-authentic, genuine, and convey the excitement of shipping something new, without resorting to hype or exaggerated claims. We value transparency and direct communication with our audience.

Task: Generate a complete three-email sequence based on the following schedule and content requirements:

**Email 1: Teaser (Send T-3 days before launch)**
*   **Purpose:** Build anticipation and hint at the upcoming launch without revealing all details.
*   **Content:** Focus on the problem {{product_name}} solves or the key improvement it brings. Hint at a solution coming soon.
*   **Output elements:**
    *   Two A/B subject line options (max 60 characters each).
    *   Preheader text (max 100 characters).
    *   Email body (150-200 words), maintaining the founder-authentic tone.
    *   Clear, single Call-to-Action (CTA) leading to a "Coming Soon" page or landing page.

**Email 2: Launch Day Announcement (Send T-0 days - on launch day)**
*   **Purpose:** Officially announce the availability of {{product_name}} and detail its primary benefits.
*   **Content:** Clearly state what has launched, its core features, and the direct value it provides. Include details on an early-adopter offer.
*   **Output elements:**
    *   Two A/B subject line options (max 60 characters each).
    *   Preheader text (max 100 characters).
    *   Email body (200-250 words), detailing {{product_name}}, its main features, and how it addresses {{key_benefit_1}}.
    *   Information about the early-adopter offer: {{early_adopter_offer_details}}.
    *   Clear, single Call-to-Action (CTA) leading directly to the product page or signup.

**Email 3: Last Chance for Early Adopter Pricing (Send T+4 days after launch)**
*   **Purpose:** Create urgency for the early-adopter offer and provide a final reminder.
*   **Content:** Reiterate the value of {{product_name}} and emphasize the limited-time nature of the early-adopter offer.
*   **Output elements:**
    *   Two A/B subject line options (max 60 characters each).
    *   Preheader text (max 100 characters).
    *   Email body (150-200 words), highlighting key benefits again and the impending end of the early-adopter offer.
    *   Clear, single Call-to-Action (CTA) with a sense of urgency.

Constraints:
*   Maintain a consistent founder-authentic, no-hype, ship-day energy tone across all emails.
*   Ensure all placeholder values (e.g., {{product_name}}, {{key_benefit_1}}, {{early_adopter_offer_details}}) are clearly identified in the generated output, rather than filled with generic text.
*   Each email must have distinct subject lines (A/B options) and preheaders.
*   CTAs should be concise and direct.
*   The email sequence should flow logically, building on the previous message.
*   The total word count for the prompt body should be between 350-900 words.

Output: Provide the full content for each of the three emails, clearly labeled by send day (T-3, T-0, T+4). For each email, include:
*   Send Timing
*   Subject Line A
*   Subject Line B
*   Preheader
*   Email Body
*   Call to Action

Editor's note

Why this prompt matters

Launching a new product or a major feature update to an existing user base requires more than a single announcement. It demands a carefully orchestrated communication strategy that builds anticipation, clearly articulates value, and motivates early adoption. Many marketers struggle to craft a sequence that feels authentic while still driving action, often defaulting to generic, hype-driven language that falls flat with a warm audience.

This workflow is designed for B2B SaaS marketers responsible for product launches. It addresses the common challenge of communicating complex value propositions in a concise, engaging, and trustworthy manner. By providing a structured framework for a three-email sequence, it ensures consistency in messaging and tone, from initial teaser to a final early-adopter push.

Reach for this workflow when you're preparing to roll out a significant product update or a new offering that warrants a dedicated launch campaign. It's particularly effective when you need to convey genuine excitement and the 'ship-day' energy of your team, without resorting to marketing jargon, ensuring your audience feels informed and valued.

Under the hood

Why this prompt works

This workflow produces effective results by employing several key prompt engineering techniques. First, role priming establishes the model as an "experienced email marketing specialist for a B2B SaaS company." This immediately sets the appropriate perspective and informs the tone and content style, moving beyond generic responses.

Explicit constraints are critical here, guiding the model on word counts for email bodies, character limits for subject lines and preheaders, and the imperative to maintain a "founder-authentic, no-hype, ship-day energy" tone. These constraints prevent verbose or overly promotional language and ensure the output is ready for direct application.

Moreover, the prompt utilizes structured output requirements by breaking down the task into three distinct emails, each with specific content goals, timing, and required elements like A/B subject lines, preheaders, body, and CTA. This sequential instruction and clear delineation of each component force the model to build a coherent narrative across the campaign, rather than generating isolated messages. The requirement to identify placeholders ensures the output is a template, not a finalized, generic text. This structured approach consistently yields a more strategic and usable email sequence compared to a single, open-ended request.

Model fit

Best AI models for this prompt

ChatGPT

ChatGPT is adept at generating varied copy and can produce effective A/B test options for subject lines and preheaders. It handles the structured output well, provided clear instructions on each email's components. Its primary limitation is occasionally requiring minor edits to fully capture the nuanced founder-authentic tone without becoming overly generic. See the full ChatGPT hub for deeper guidance.

Claude

Claude excels at maintaining specific tones and adhering to complex constraints, making it suitable for this prompt's founder-authentic requirement. It produces coherent and contextually relevant email body text that flows naturally. While strong on tone, it might sometimes require a second pass to ensure the CTAs are as direct and action-oriented as needed. See the full Claude hub for deeper guidance.

Gemini

Gemini is effective for producing structured output, which is crucial for delivering distinct subject lines, preheaders, and email bodies for each stage. It adapts well to persona requirements, generating copy that aligns with the founder-authentic, no-hype energy. Its main challenge can be balancing the desired brevity with comprehensive information for each email, sometimes needing refinement for conciseness. See the full Gemini hub for deeper guidance.

When to use

  • When launching a new B2B SaaS product or major feature to your existing customer base.
  • To announce a time-sensitive early-adopter pricing or limited-time offer for a new offering.
  • For generating initial excitement and immediate adoption from a warm, engaged audience.
  • When the product or feature provides a clear, tangible benefit to current users.
  • If you aim to convey a direct, genuine message from the founding team about a new release.

When not to use

  • For cold outreach to an entirely new, unqualified audience without prior engagement.
  • When promoting a minor update or bug fix that doesn't warrant a multi-email sequence.
  • If your product is B2C and requires a different communication style or offer structure.
  • When there is no specific launch date or early-adopter incentive to drive urgency.
  • For purely informational announcements without a clear call to action or adoption goal.

Pro tips

  • 1

    Ensure the "Coming Soon" page for Email 1 provides a clear next step, like an email signup for updates, to capture early interest. This prevents lost engagement.

  • 2

    Test different early-adopter offer structures. A discount versus added features can significantly impact conversion rates. This addresses offer effectiveness.

  • 3

    Match your subject line A/B tests to specific hypotheses, like urgency versus benefit-driven. This helps refine future campaign performance.

  • 4

    Verify all placeholders are correctly filled and relevant to your specific product and audience. Generic content dilutes authenticity.

  • 5

    Consider segmenting your existing list further if specific user groups would benefit from tailored messaging or offers. This improves relevance.

  • 6

    Keep the CTA concise and action-oriented. Ambiguous calls to action reduce click-through rates and user clarity.

Don't ship this

Common mistakes

  • Using generic placeholders like `{{product_name}}` in the final email copy, making the message impersonal.

    Fix — Always replace these with your actual product name and specific details before sending to maintain authenticity and relevance.

  • Inconsistent tone across the three emails, losing the founder-authentic voice by the third message, which can confuse readers.

    Fix — Review the entire sequence for a consistent, genuine, ship-day energy that resonates with your audience and builds trust.

  • CTAs that are vague or lead to a generic homepage, causing user confusion and drop-off.

    Fix — Ensure each CTA is specific, directs to the relevant product or offer page, and clearly states the desired action for the recipient.

  • Failing to clearly articulate the early-adopter offer's value or its expiry in Email 2 and 3, reducing urgency.

    Fix — Highlight the unique benefit of the offer and its time limit prominently to drive urgency and perceived value effectively.

  • Overloading email bodies with too many features or technical details, overwhelming the reader and diluting the main message.

    Fix — Focus on the primary benefits and the core problem solved, keeping the copy concise and digestible for quick scanning.

Frequently asked questions

Q.Can this sequence be adapted for a B2C product launch?

This sequence is tailored for B2B SaaS, emphasizing founder-authentic tone and specific offers. While adaptable, B2C often requires different emotional triggers, imagery, and offer types to connect with consumers effectively.

Q.How critical are the specific send timings (T-3, T-0, T+4)?

The timings are strategic for building anticipation and urgency. Adjusting them significantly might impact the sequence's effectiveness, especially for time-sensitive offers. Consider your audience's typical engagement patterns.

Q.What if I don't have an early-adopter offer? Can I still use this?

Yes, but you'll need to modify Email 2 and 3. Instead of an offer, focus on the unique value proposition, benefits, and perhaps a free trial incentive or exclusive content for early sign-ups.

Q.Should I personalize these emails beyond the placeholders?

Absolutely. Incorporating the recipient's name, company, or previous interactions can significantly boost engagement and reinforce the founder-authentic connection, making the message feel more direct.

Q.My product launch is very complex. Is this three-email sequence enough?

For highly complex launches, a three-email sequence might be too brief. Consider adding a pre-launch webinar, more detailed explainer content, or a follow-up email after the offer expires to address more nuances.

Q.How important is the 'Coming Soon' page mentioned in Email 1's CTA?

It's crucial. This page validates the teaser, captures early interest, and provides a clear next step for eager recipients, preventing the email from feeling like a dead end. It sets the stage for the full launch.
