Subject: Proposal — Joint Customer Feedback Loop to Inform Product Roadmap Hi Jordan, I hope you’re well. I’m reaching out to propose a cross-department initiative to create a structured customer feedback loop that channels user insights gathered by marketing campaigns directly into the product roadmap.

Subject: Proposal — Joint Customer Feedback Loop to Inform Product Roadmap Hi Jordan, I hope you’re well. I’m reaching out to propose a cross-department initiative to create a structured customer feedback loop that channels user insights gathered by marketing campaigns directly into the product roadmap. Over the last two quarters our campaigns have surfaced recurring requests and friction points that I believe could help prioritize features and reduce churn if handled in a coordinated way. Why this matters: Marketing can surface validated patterns from messaging tests, onboarding analytics, and customer conversations; Product can use those signals to make faster, higher-confidence roadmap decisions. Together we can close the loop from user signal to product outcome. Three specific benefits: 1) For Marketing: more relevant campaigns and messaging informed by product plans and feature timelines, improving conversion and retention. 2) For Product Development: prioritized, evidence-based roadmap items driven by aggregated user signals—shortening discovery time and lowering the risk of building the wrong thing. 3) For the company: faster iteration cycles, clearer cross-functional priorities, and improved customer satisfaction from aligning product outcomes with market needs. Next steps: If this sounds useful, I suggest a 30–45 minute kickoff meeting within the next one to two weeks to outline scope, identify a pilot product or segment, and agree on success metrics. I’m available Tuesday or Thursday mornings, or I can work around your schedule. For the meeting I can bring recent campaign insights and a proposed handoff template so we have a tangible starting point. Please let me know what you think or suggest an alternative approach or timing. I’m happy to adapt the plan to fit your team’s priorities. Best regards, Alex Martinez Marketing Manager

This email is well-crafted and meets nearly all the requirements of the task. The subject line is clear and specific, the greeting is appropriate, and the body is logically organized. The proposal is explained concisely and without unnecessary jargon, making it accessible to someone outside marketing. The three benefits are distinct and concrete, with benefit two explicitly framed from the Product Development perspective, which satisfies the key requirement. The next steps are specific and actionable, including a proposed timeframe, meeting duration, available time slots, and a mention of materials to bring. The tone is professional yet approachable, avoiding stiff corporate language. The word count falls comfortably within the 200–400 word range. There are no placeholder brackets, and the email reads as ready to send. Minor weaknesses include the slightly bulleted, list-heavy structure in the benefits section, which could feel slightly impersonal, and the benefits, while solid, could be even more specific to the company's context. Overall, this is a strong, complete, and persuasive professional email.

Appropriateness
Weight 25%The email is fully appropriate for the context. It addresses the right person, proposes a relevant initiative, frames benefits for both departments, and avoids jargon. No placeholder text is present and the email is ready to send. The framing is respectful of the recipient's time and perspective.
Clarity
Weight 20%The initiative is explained clearly and concisely. The feedback loop concept is described in plain language accessible to someone outside marketing. The rationale is logical and easy to follow. The only minor gap is that the email could be slightly more specific about what 'recurring requests and friction points' were observed, but this is a minor issue.
Structure
Weight 20%The email has a clear subject line, proper greeting, well-organized body with distinct sections for context, benefits, and next steps, and a professional sign-off. The use of numbered benefits aids readability. The transition between sections is smooth. The structure is clean and professional.
Actionability
Weight 20%The next steps are highly specific: a 30-45 minute meeting, a one-to-two week timeframe, specific available days, and a mention of materials to bring. This goes beyond vague suggestions and gives the recipient everything needed to respond and move forward. This is one of the strongest aspects of the email.
Tone
Weight 15%The tone strikes a good balance between professional and approachable. Phrases like 'If this sounds useful' and 'I'm happy to adapt the plan' keep it conversational without being casual. The email avoids overly stiff corporate language and reads naturally. Slightly more warmth in the opening could elevate it further, but overall the tone is well-calibrated.

This is a strong, professional email that clearly proposes the collaboration, explains its value to both teams, and includes concrete next steps. It is well organized and easy to follow, with an appropriate tone and sufficient specificity about the feedback loop. Minor limitations are that the benefits section is somewhat list-like and the proposal could be even more tailored to Product Development’s likely workflow or decision-making process.

Appropriateness
Weight 25%The email fits the workplace scenario very well, directly addresses the Head of Product Development, and proposes a relevant cross-functional initiative. It includes clear mutual value and avoids generic filler. It is slightly less than outstanding only because it could show a bit more customization to Jordan’s department priorities or current product process.
Clarity
Weight 20%The proposal is explained in straightforward language, and the idea of routing marketing-generated user insights into the product roadmap is easy to understand without heavy jargon. The reason it matters is clearly stated, and the three benefits are distinct. A small improvement would be to define more concretely how the feedback loop would operate on an ongoing basis.
Structure
Weight 20%The response has an effective subject line, proper greeting, well-separated body sections, a clearly labeled benefits list, actionable next steps, and a professional sign-off. The flow is logical and polished. It fully meets the expected email format.
Actionability
Weight 20%The next steps are specific and practical: a 30–45 minute kickoff within one to two weeks, discussion topics, proposed timing, and materials to bring. This makes the proposal easy to respond to. It would be even stronger with one more detail about ownership or a suggested follow-up deliverable after the meeting.
Tone
Weight 15%The tone is professional yet approachable throughout. It is confident without sounding pushy and collaborative without being overly casual. The wording is polished and respectful, and it leaves room for questions or alternative suggestions.
