Rapid QA Checklist for AI-Generated Email Copy

Hook: Send faster, but don’t break the inbox — a 10-minute QA playbook for AI-generated emails

Teams are shipping AI-written emails faster than ever — and with that speed comes tone drift, factual slip-ups, and deliverability risks that quietly tank performance. This playbook gives you a repeatable, timed QA checklist you can run in under 10 minutes before any send. Use it to catch tone problems, AI hallucinations, spam triggers, and privacy or compliance misses that cost opens, clicks, and trust.

Why a rapid QA matters in 2026

Late 2025 and early 2026 changed the inbox. Google’s Gemini-era features in Gmail introduced AI Overviews and deeper message analysis, and industry conversations — from Merriam-Webster naming “slop” its 2025 Word of the Year to deliverability experts warning about AI-sounding language — put a premium on high-quality copy and reliable send hygiene.

That means a single, speedy QA pass can save campaigns: preserve brand voice, avoid AI-style generic phrasing that reduces engagement, and prevent simple errors that trigger spam filters or legal trouble.

“AI-sounding language can negatively impact email engagement” — observations from deliverability and marketing practitioners in late 2025 and early 2026.

How to use this playbook

This is a practical, timed checklist sized for fast-moving teams. Each step has a suggested time budget so your team can run a full QA pass in under 10 minutes. Pair it with a quick human scorecard and one AI-assisted check if you have an internal assistant.

Before you start, open the live email in your ESP, the raw HTML (or staging preview), and a seed inbox (Gmail, Outlook, and Apple Mail) if possible.

Rapid 10-minute QA checklist (timeboxed)

1. 0:00–0:30 — Subject line + Preheader (30 seconds)

   What to check: length, preview alignment, token fallbacks, obvious spam words, and clarity of value.

   • Subject length: keep it readable in Gmail mobile preview (under ~50 characters when possible).
   • Preheader: complements the subject, not repeats it — preview should add context.
   • Personalization tokens: ensure fallback text exists to avoid raw tokens like {{firstName}}.
   • Spam triggers: remove ALL-CAPS, multiple exclamation points, and overtly promotional phrases like “100% FREE” or “ACT NOW!!!”.

2. 0:30–1:00 — From name + Reply-to + Segment sanity (30 seconds)

   What to check: sender consistency and correct audience targeting.

   • From name aligns with the relationship (brand, product manager, or person).
   • Reply-to is monitored — a no-reply address is often a conversion blocker.
   • Confirm segment: correct list, suppression applied, and no accidental cross-segment sends.

3. 1:00–2:00 — Tone check and “de-AI” pass (60 seconds)

   What to check: does the copy sound human, specific, and aligned to the brand persona?

   • Read the opening sentence aloud. If it sounds like a boilerplate headline, mark for rewrite.
   • Look for overused AI-signatures: vague verbs (optimize, leverage), bland superlatives, and generic anecdotes.
   • Replace at least one generic sentence with a concrete detail (date, number, quote, or customer name).

   Quick prompt to “de-AI” with your internal assistant: rewrite the first two paragraphs to sound like a friendly product lead, include one specific metric, and remove generic phrases like “best-in-class.” See prompt techniques like From ChatGPT prompt to TypeScript micro app for concise prompt patterns.

4. 2:00–3:00 — Factual accuracy and offer check (60 seconds)

   What to check: dates, prices, promo codes, deadlines, and product names.

   • Verify every numeric claim against the CMS or product team (prices, discounts, availability).
   • Confirm promo codes work and have correct expiry dates.
   • Validate event dates/times and timezone clarity for recipients.

5. 3:00–4:00 — Links, UTM tags, and redirect safety (60 seconds)

   What to check: every link lands where it should, has correct UTM, and avoids risky redirects.

   • Click every link in the live preview. Confirm final landing domain is your brand or a trusted partner.
   • Check UTM parameters for accuracy and consistent campaign naming conventions.
   • Watch for long redirect chains or third-party shorteners that can trigger spam filters or break tracking.

6. 4:00–5:00 — Spam and deliverability quick scan (60 seconds)

   What to check: content triggers and basic authentication readiness.

   • Quick visual content checks: excessive punctuation, multiple currency symbols, and misleading subject lines.
   • Run a one-click content spam score if your ESP or a tool is available (mail-tester, Litmus, or deliverability plug-ins).
   • Confirm domain authentication is in place or confirm with your deliverability lead that SPF/DKIM/DMARC alignment is OK for this campaign.

   Note: full deliverability audits take longer, but a 60-second check prevents common traps.

7. 5:00–6:00 — Accessibility and mobile rendering (60 seconds)

   What to check: plain-text version, alt text, contrast, and whether the email is readable on a small screen.

   • Preview mobile layout and confirm CTA buttons are tappable and visible without scrolling.
   • Check alternative text for critical images and ensure the plain-text fallback communicates the essential message.
   • Verify language attribute in header if sending localized content.

8. 6:00–7:00 — Legal, privacy, and unsubscribes (60 seconds)

   What to check: required disclosures, unsubscribe link, and suppression rules.

   • Unsubscribe link is present, working, and easy to find.
   • Include mandatory business address or required footer items for regional laws (CAN-SPAM, CASL, GDPR references when necessary).
   • Confirm privacy-sensitive content uses only approved PII and follows consented communication lists. Refer to privacy-first personalization guidance for handling tokens and consent.

9. 7:00–8:00 — A/B flags and tracking controls (60 seconds)

   What to check: A/B test markers, control groups, and analytics tagging.

   • Confirm which variant is active and that control group recipients are excluded from other campaigns.
   • Verify analytics tags and event tracking for accurate attribution (instrumentation and observability guidance can help here: Modern Observability in Preprod Microservices).

10. 8:00–9:00 — Inbox preview test sends (60 seconds)

    What to check: send a 3-inbox preview to Gmail, Outlook, and Apple Mail.

    • Check the subject + preheader display, sender name, and whether the content triggers any warnings or image blocking.
    • Confirm personalization tokens resolved correctly and images load (or show alt-text when blocked).

11. 9:00–10:00 — Final approval checklist (60 seconds)

    What to check: schedule, throttling, and approval sign-off.

    • Confirm send window and time zone; apply throttling if needed for deliverability testing.
    • Get a final quick approval: Approve / Revise / Escalate.
    • Document quick notes: what was changed and why.

Human Review Scorecard — 60 seconds

Use a 3-question pass/fail scorecard to speed approvals. If any fail, stop the send and fix the issue.

• Tone match: Does the email reflect the brand persona? (Pass/Fail)
• Factual checks: Are dates, pricing, and links accurate? (Pass/Fail)
• Deliverability risk: Any spam triggers, broken links or missing authentication? (Pass/Fail)

If all three are pass, sign off and send. If any fail, flag the issue, allocate 5–30 minutes for fixes, and re-run the quick QA.

AI-assisted checks and prompts for a second pair of eyes

If you use an internal AI reviewer, here are three short prompts you can run in 10–20 seconds each to catch common issues.

1. Tone heuristic prompt

   “Analyze the email body and subject. List up to five phrases that sound generic or AI-like and suggest a one-sentence rewrite for each into a more human, specific version.”

2. Hallucination and factual check prompt

   “Find sentences that make specific factual claims (dates, numbers, awards) and flag them for verification. Output the exact text to verify and a suggested source to check.” See generative-AI verification approaches in reconstructing fragmented web content.

3. Spam-risk prompt

   “Scan the email and return a list of words and constructs likely to raise spam scores. Provide a severity rating (low/medium/high) and two alternative phrasings for each high-risk item.”

Common red flags to stop the send immediately

• Broken or malicious links (link goes to an unexpected domain or 404).
• Raw personalization tokens visible in preview or test sends.
• Incorrect promo codes, wrong dates, or mismatched price information.
• Missing unsubscribe link or a footer that violates local email laws.
• High volume of AI-style generic phrasing in the first two sentences — this has been correlated with lower engagement.

Deliverability specifics for 2026

Deliverability is more contextual than ever. Gmail’s AI Overviews and expanded machine-learning classifiers evaluate signals beyond classic spam rules. In practice:

• Consistency matters: From name, sending domain, and cadence are signals Gmail and other providers use to build trust.
• Quality matters: AI-sounding, generic copy is more likely to be deprioritized in smart inboxes that create summaries or fold messages into less prominent views.
• Authentication still matters: SPF/DKIM/DMARC alignment and domain reputation remain foundational — ensure DNS changes are propagated before big sends.

Tools to keep handy: deliverability dashboards in your ESP, Google Postmaster Tools, mailbox provider dashboards, and third-party scanners like Litmus, Mail-Tester, and GlockApps for pre-send checks.

Short real-world example

A product team in late 2025 found their open rates dropped after switching to AI-first subject generation. After introducing a 10-minute QA that included a tone read-aloud and subject + preheader alignment, they reduced vague subject lines and regained higher early opens. The team paired the checklist with a one-sentence humanization rule: add a specific stat, user quote, or date to the first two lines.

Lesson: small, repeatable QA steps protect inbox performance and brand trust — and they scale with your AI workflows.

Tips to embed this checklist into your workflow

• Make the checklist part of the ESP send flow: require a quick QA sign-off before the final send button.
• Assign roles: writer, reviewer, and deliverability owner. One person runs the 10-minute QA, another signs off.
• Maintain a short “safety playbook” for recurring errors (token fallbacks, common spam words, standard legal footer).
• Collect metrics: track how often the QA finds issues and which fixes improve open and click rates. Instrumentation guidance such as modern observability can help validate tracking.

Final checklist summary — ready to run

When the clock is ticking and you must send quickly, run this exact sequence: subject/preheader → sender → tone → facts → links → spam scan → accessibility → compliance → seed sends → sign-off. It’s a focused, defensible process that prevents the most common AI-era mistakes.
