- Brief rationale (one sentence on benefit or curiosity hook)
- Complementary preheader (50–90 characters; adds context; does not repeat the subject). Include character count.
- Two versions: with emoji and without emoji (only if allowed by Emoji policy). Recommend specific emoji only if policy is LIMITED/OK.

SECTION 2: 5 ADDITIONAL OPTIONS
- Provide 5 more subject lines with character counts and one-sentence rationales.
- Label each with its type: curiosity-led, benefit-led, action-led, or personalized.
- Mix across all 7 total: 2 curiosity-led, 2 benefit-led, 2 action-led, 1 personalized (uses [FIRST NAME TAG] or [CITY TAG] with fallback).

SECTION 3: PREHEADERS FOR THE 5 ADDITIONAL OPTIONS
- Provide a matching preheader for each (50–90 characters; add context; no repetition of the subject). Include character counts.

SECTION 4: SPAM & DELIVERABILITY CHECK
- Flag any potential triggers (FREE, URGENT, ACT NOW, $$$, ALL CAPS, excessive punctuation like !!! or ???).
- If any appear, provide a clean rewrite immediately below.
- Note any risky phrasing and how you mitigated it.

SECTION 5: A/B TEST RECOMMENDATION
- Choose two subject lines to test.
- Select ONE variable: emoji vs none, benefit vs curiosity, personalized vs generic, or short vs long.
- Hypothesis: “We predict [VERSION A] will perform better because [REASON].”
- Success metric: open rate (nonprofit benchmark ~20–25%). Note any list-specific considerations.

- Reading level: 6th–8th grade; short, clear sentences; nonprofit voice.
- Lead with benefit or thoughtful curiosity; avoid clever-but-unclear wording.
- Action-oriented verbs; highlight real impact (e.g., “your gift provides [IMPACT/UNIT]”).
- Avoid guilt trips, bait-and-switch, ALL CAPS, excessive punctuation, spammy language.
- Personalization: include merge tags only when they add value; always include a fallback term.
- Accessibility: do not rely on emoji alone; ensure meaning stands without emoji.
- Paste-ready for small teams using [EMAIL PLATFORM]; keep formatting simple.
- Test one variable at a time; document outcomes for learning.

NOTES ON CHARACTER COUNTS AND PREVIEWS
- 40–60 characters generally shows well on mobile and most inboxes.
- 60–70 characters can work for desktop-heavy audiences or when clarity needs a few extra words.
- Always put the most important words first to survive truncation.

SECTION 5: A/B TEST RECOMMENDATION

AI Evaluation Details (Score: 9.2/10)
Reasoning:

This output excellently matches the casual, local tone requested for a rural animal rescue. It delivers highly actionable, paste-ready content with strong nonprofit best practices. Minor weaknesses include a small formatting inconsistency in Section 2 and slightly generic phrasing in one curiosity line, but overall this is professional-grade work a small nonprofit could deploy immediately.

Strengths:
  • Perfect tone calibration: casual, warm, and community-focused without being unprofessional (e.g., 'Your winter roommate might have four paws…')
  • Strong local relevance throughout: 'Red Willow' appears in multiple subject lines, reinforcing geographic connection
  • Concrete, mission-aligned impact statements: '1 foster = 3 lives saved' is clear, memorable, and motivating
  • Excellent preheader strategy: each adds context without repeating the subject line, maximizing preview-pane real estate
  • Thoughtful personalization: Section 2 #5 correctly uses merge tags with fallback logic documented
  • Clean deliverability: no spam triggers, appropriate emoji use per LIMITED policy, professional language throughout
  • Actionable A/B test design: single-variable test (emoji vs none) with clear hypothesis tied to audience demographics
  • Practical From Name recommendations: 'Maya, Red Willow Animal Rescue' balances personal touch with organizational credibility
  • Character counts are accurate and well-optimized for mobile (most 42-57 characters)
  • Section 4 spam check is thorough and correctly identifies zero issues
Weaknesses:
  • Minor formatting inconsistency in Section 2 #4 and #5: uses '[ City ]' and '[ First Name ]' with spaces inside brackets, while the scenario specifies '[City]' and '[First Name]' without spaces—could cause merge-tag failures in Constant Contact
  • Section 2 #1 ('What happens when one home opens up in winter?') is slightly generic and could apply to many causes; more animal-specific language would strengthen authenticity
  • Section 6 could have included one additional tactical note about testing 'Maya' vs 'Foster Team' as a secondary variable for future campaigns

SECTION 1: TOP 2 SUBJECT LINES (Ready to A/B test)

Option A - Subject: {{FirstName}}, $50 = a week of after-school art (47) - Rationale: Personalization plus a clear $50 impact creates ownership and clarity for lapsed donors. - Preheader: Sponsor one Baltimore student’s week of after‑school art by Dec 2. (66) - With emoji: {{FirstName}}, $50 = a week of after-school art 🎨 (49) - Without emoji: {{FirstName}}, $50 = a week of after-school art (47)

Option B - Subject: Giving Tuesday: what $50 does for one student (45) - Rationale: Curiosity hook leads into the concrete impact of a $50 gift. - Preheader: Hint: your gift today sponsors a week of after‑school art in Baltimore by Dec 2. (80) - With emoji: Giving Tuesday: what $50 does for one student 🎁 (47) - Without emoji: Giving Tuesday: what $50 does for one student (45)

SECTION 2: 5 ADDITIONAL OPTIONS

1) Your $50 sponsors a week of after‑school art (44) - Type: benefit-led - Rationale: Highlights the direct, tangible outcome of a $50 gift.

4) Beat the Dec 2 Giving Tuesday deadline—give $50 (47) - Type: action-led - Rationale: Time-bound nudge tied to Giving Tuesday and a simple action.

5) See what your last gift sparked—and how $50 builds on it (56) - Type: curiosity-led - Rationale: Re-engages lapsed donors by connecting past impact to a specific next step.

SECTION 3: PREHEADERS FOR THE 5 ADDITIONAL OPTIONS

1) Your $50 sponsors a week of after‑school art - Preheader: On Giving Tuesday, your gift funds one student’s week of art in Baltimore by Dec 2. (83)

2) In Baltimore, $50 opens a week of art classes - Preheader: Help a Harbor Youth Arts student create after school—one week, one gift, by Dec 2. (82)

5) See what your last gift sparked—and how $50 builds on it - Preheader: You helped us light a creative spark. This Giving Tuesday, $50 keeps it shining. (80)

SECTION 4: SPAM & DELIVERABILITY CHECK

- Potential triggers flagged: None. We avoided ALL CAPS, FREE, URGENT, ACT NOW, multiple punctuation (!!!/???), and excessive emojis. - Currency symbol ($) and an em dash (—) are generally safe; we used one emoji only in A/B variants per LIMITED policy. - Personalization note: Ensure {{FirstName}} has a fallback of “friend” to prevent empty tags. - No rewrites needed.

SECTION 5: A/B TEST RECOMMENDATION

- Test these two: - Variant 1 (personalized/benefit): {{FirstName}}, $50 = a week of after-school art - Variant 2 (generic/curiosity): Giving Tuesday: what $50 does for one student - Variable: personalized vs generic - Hypothesis: We predict personalized will perform better because lapsed donors are more likely to re-engage when they see their name and a clear, concrete impact. - Success metric: Open rate (aim for 20–25% benchmark; lapsed segment may run lower—consider a resend to non-openers with the winning line).

SECTION 6: FROM NAME RECOMMENDATION

- Primary: Maya Thompson at Harbor Youth Arts - Alternate: Marcus Lee, Harbor Youth Arts

Why this fits: A real staff name plus the organization builds trust and warmth for an appeal, especially with lapsed donors, while keeping Harbor Youth Arts recognizable in the inbox.

Reasoning:

This output is highly professional and actionable, delivering subject lines that appropriately balance warmth, clarity, and impact messaging for a lapsed donor audience. The structure is complete and follows the template precisely, though there are minor inconsistencies in the from-name section. The content would be immediately usable by a nonprofit communications team.

Strengths:
  • Excellent character count discipline—all subject lines fall within the 40-60 character sweet spot, with accurate counts provided throughout
  • Strong personalization strategy that appropriately targets lapsed donors with concrete impact messaging ($50 = 1 week) rather than guilt-based appeals
  • Well-constructed A/B test recommendation with a clear hypothesis grounded in audience psychology and a realistic acknowledgment that lapsed segments may underperform benchmarks
  • Preheaders consistently add context without repeating subject lines, and effectively incorporate location (Baltimore) and deadline (Dec 2) where relevant
  • Spam/deliverability check is thorough and correctly identifies no major triggers; appropriate use of LIMITED emoji policy
  • Good mix of subject line types across the seven options (benefit-led, action-led, curiosity-led, personalized) as specified
Weaknesses:
  • Section 6 from-name recommendation introduces two new staff names (Maya Thompson, Marcus Lee) that don't match the scenario input which specified 'Alicia Bennett' as the staff/CEO name—this creates confusion and would require the user to substitute the correct name
  • Option B's preheader in Section 1 uses 'Hint:' which, while not spam-triggering, feels slightly gimmicky for a warm tone and lapsed donor audience—a more straightforward approach might be stronger
  • The curiosity-led option in Section 2 (#5: 'See what your last gift sparked') assumes the lapsed donor will remember their previous gift, which may not resonate if they gave 24-36 months ago; this could have been flagged as a potential risk

SECTION 1: TOP 2 SUBJECT LINES (Ready to A/B test)

SECTION 5: A/B TEST RECOMMENDATION

- Test these two: • Option A (action-led): Please sign to defend the Clean Water Rule • Option B (benefit-led): Every 50 signatures alerts key lawmakers - Variable: Benefit-led vs action-led - Hypothesis: Benefit-led will outperform because policy-engaged supporters respond to quantified impact (every 50 signatures triggers a lawmaker alert). - Success metric: Open rate (target ≥20–25% benchmark). Consider that a national, policy-engaged list may skew higher; send to a 10–20% test segment first, declare winner after 2–4 hours, then send the winner to the remainder.

SECTION 6: FROM NAME RECOMMENDATION

- Primary: CEO, Global Water Trust - Alternate: Office of the CEO, Global Water Trust Note: A CEO-anchored from name lends authority and aligns with a formal advocacy alert to policy-engaged partners, signaling institutional credibility without over-personalization.

AI Evaluation Details (Score: 8.8/10)
Reasoning:

This output demonstrates excellent understanding of formal advocacy communications and delivers highly usable, professional subject lines. The tone is appropriately formal without being stiff, and the benefit-led framing (50 signatures = lawmaker alert) is strategically sound for policy-engaged audiences. Minor deductions for a few character-count inconsistencies and one slightly long personalized subject line.

Strengths:
  • Perfect tone calibration: formal, clear, respectful language appropriate for policy-engaged national audience without jargon or emotional manipulation
  • Strong strategic framing: the '50 signatures = lawmaker alert' mechanism is concrete, credible, and motivating for advocacy-savvy supporters
  • Excellent spam avoidance: completely clean of triggers while maintaining urgency through deadline and specific policy reference
  • Smart A/B test design: benefit vs. action is a meaningful variable with a well-reasoned hypothesis grounded in audience characteristics
  • Appropriate CEO from-name recommendation with clear institutional rationale for formal advocacy context
  • All 7 subject lines are genuinely distinct and usable, not just minor variations
  • Preheaders consistently add context without repetition and stay within character limits
Weaknesses:
  • Minor character count discrepancy: Section 1 shows '(42)' and '(40)' but actual counts are 43 and 40 respectively when measured precisely
  • Personalized subject line in Section 2 (#5) is 57 characters—pushes upper limit and may truncate on mobile; could be tightened
  • The alternate from-name 'Office of the CEO' feels slightly bureaucratic; 'Dr. Lena Cho, Global Water Trust' would be warmer while maintaining formality
  • Curiosity-led option #1 ('What happens if we miss...') borders on fear-based framing, which may feel slightly off-tone for this formal context, though still acceptable
