Subject: Thank you, Caleb — your June harvest powered 60 households | Maple Ridge Community Garden
Dear Caleb Johnson (he/him),
Thanks for jumping into our Saturday harvest and produce share in June 2025. As a FIRST-TIME volunteer (started 06/08/2025), you harvested and packed 180 lbs of produce. That directly supports our mission: Grow and share healthy food with neighbors facing food insecurity.
In total, you gave 6 hours in June. That effort helped deliver 180 lbs of vegetables, providing fresh produce for 60 households. A favorite moment: when a neighbor asked about kale, you shared a quick recipe that sent them home excited to try it.
You’re part of the Green Thumbs Crew now, and your presence makes the garden welcoming. We’re glad you’re here.
No pressure, but if you want a next step, join our community potluck on July 12 at the garden. Come say hi, swap recipes, and meet fellow volunteers.
With gratitude, Rosa Martinez, Volunteer Coordinator, rosa@mapleridgegarden.org | 802-555-0142
P.S. Your June shift helped stock fresh produce for 60 households.
AI Evaluation Details (Score: 7.8/10)
The output successfully captures a casual, warm tone appropriate for a small community garden and includes most required elements. However, it suffers from redundancy (repeating the same metrics multiple times), slightly exceeds the word count target, and includes some awkward phrasing that reduces authenticity. The letter would work in practice but needs minor editing.
- • Excellent casual tone that fits the Vermont community garden context—conversational without being unprofessional
- • Strong specific example (kale recipe moment) that feels genuine and community-oriented
- • Good use of inclusive pronouns and welcoming language ('You're part of the Green Thumbs Crew now')
- • Clear, actionable next step (potluck) with no fundraising pressure
- • Subject line is informative and impact-focused
- • Appropriate reading level and scannable structure
- • Significant redundancy: '180 lbs of produce' appears three times, '60 households' appears twice, creating repetitive feel
- • Word count is ~215 words, slightly over the 150-220 target (acceptable but could be tighter)
- • Awkward phrasing: 'As a FIRST-TIME volunteer (started 06/08/2025)' reads like database output rather than natural language—should integrate more smoothly
- • P.S. repeats June/60 households information already stated, missing opportunity for a different compelling stat
- • Minor: 'That effort helped deliver 180 lbs of vegetables' is redundant when already stated in previous sentence
- • The signature block lacks the handwritten signature alt-text note that was provided in the input data

Subject: Thank you, Priya — your leadership grew young coders at City Tech Tutors
Dear Priya Shah (she/her),
Thank you for leading our After-school coding club at Lincoln Middle School during Jan–Mar 2025. As a TEAM LEAD since 2023, you mentored 4 students weekly on Python basics and debugging. Your service advances our mission: Expand access to STEM learning for middle-school youth in our city.
In total, you gave 36 hours Jan–Mar and led 9 sessions; 4 student projects were completed. Efforts like yours contributed to a 20% increase in students completing projects this quarter. One moment we loved: Jamal finished his first game after you guided him through a tricky loop bug.
You’re a valued part of the Coder Coach Network. Your calm coaching makes the club welcoming and brave for new coders. If you’d like a next step, we hope to see you at spring training on April 18 at 6 p.m.—totally optional, and a good way to swap tips with peers.
With gratitude, Marcus Lee Program Manager volunteers@citytechtutors.org | 312-555-0199
P.S. Your leadership helped drive a 20% uptick in completed student projects this quarter.

This is a high-quality, professional volunteer thank-you letter that successfully balances warmth with specificity. It follows the template structure precisely, incorporates all provided data naturally, and avoids common nonprofit communication pitfalls like clichés and fundraising language. The letter feels genuine and actionable.
- • Excellent use of specific, quantified impact (36 hours, 9 sessions, 4 projects, 20% increase) that makes appreciation concrete and meaningful
- • Strong personalization using all provided fields naturally—pronouns, tenure, team lead role, and community name are woven in smoothly
- • The Jamal anecdote is positioned perfectly and adds authentic human connection without being overwrought
- • Subject line is concise, personal, and action-oriented ('your leadership grew young coders')
- • Word count (199 words) falls perfectly within the 150-220 target range
- • Reading level is accessible with short sentences and clear structure; highly scannable with logical paragraph breaks

- • Next touchpoint invitation is low-pressure and includes practical benefit ('swap tips with peers')
- • P.S. reinforces impact without being repetitive, using slightly different phrasing than body
- • Zero fundraising language or donation asks, as required
- • Completely avoids clichés like 'rockstar' or 'couldn't do it without you'
- • Minor redundancy: the 20% project completion metric appears in both paragraph 2 and the P.S., though phrased differently—could have used a distinct stat in P.S. for variety
- • The phrase 'welcoming and brave' in paragraph 3, while contextually appropriate for coding education, is slightly abstract compared to the concrete language elsewhere
- • Signature image alt-text was provided but not explicitly noted in output (though this is a very minor formatting omission for email context)

Subject: Thank you, Derrick — your leadership at Lakeview Preserve | Great Lakes Habitat Conservancy
Dear Derrick O’Neal (they/them),
Thank you for leading at the Wetland restoration weekend at Lakeview Preserve this spring. As a TEAM LEAD volunteering since 2019 (220 total hours), you kept the work organized and safe, advancing our mission: Protect and restore freshwater habitats for wildlife and people across our region.
Across 24 hours this spring, you led a crew of 12 to plant 450 native sedges and remove 300 lbs of invasive grass. That work improved 2.5 acres of wetland for 3 at-risk bird species. One moment stands out: Your safety huddle kept everyone hydrated and focused during the unexpected heat spike.
You are a valued part of our Habitat Crew. Your calm leadership helps new volunteers feel welcome.
As a next step, please join us at the annual Volunteer Summit on May 21—no pressure, just an open invitation.
With gratitude, Elena Kovacs Director of Volunteer Engagement team@glhabitat.org | 216-555-0220 Signature of Elena Kovacs included for accessibility.
P.S. Your service helped improve 2.5 acres of wetland for 3 at-risk bird species.
AI Evaluation Details (Score: 8.2/10)
The letter successfully delivers a formal, respectful tone appropriate for a team lead with significant tenure. It includes strong specifics and quantified impact. However, it has minor structural issues: the P.S. duplicates impact already stated, word count slightly exceeds target, and some phrasing feels mechanical rather than warmly formal.
- • Excellent use of specific data (450 plants, 300 lbs, 2.5 acres, 3 bird species) that demonstrates real impact
- • Appropriate formal tone that respects the volunteer's leadership role and 5-year tenure without being stiff
- • Strong personalization with pronouns, tenure milestone, and the specific safety huddle anecdote
- • Clean structure that works for print delivery as requested
- • Effective recognition of leadership qualities ('calm leadership helps new volunteers feel welcome')
- • Word count is approximately 165 words (body only), which is within range but could be tighter for scannability
- • P.S. repeats the 2.5 acres metric already mentioned in paragraph 2—should offer a different stat or broader program impact
- • The phrase 'kept the work organized and safe' in paragraph 1 is somewhat generic; could be more specific to wetland restoration context
- • Minor awkwardness: 'TEAM LEAD' appears in all caps when it should be title case for formal tone
- • The signature accessibility note ('Signature of Elena Kovacs included for accessibility') is slightly awkward phrasing for print context—could simply state the alt-text or omit the explanation
