AI Content Policy

Requirements

All warmup email subjects and bodies must be:

Professional B2B tone
Contextually appropriate to industry (Childcare, SaaS, Finance, etc.)
Free of spam trigger words (see blocklist)
Free of placeholders — no [Name], [Your company], {{variable}}, etc.
Plain text only (MVP) — no HTML, images, tracking pixels, or links in warmup mail
Unique enough across sends — no identical consecutive bodies

Forbidden patterns (auto-reject)

Regex / validation pass after generation:

\[.*?\]          # bracket placeholders
\{\{.*?\}\}      # mustache
<.*?@.*?>        # angle email placeholders in body
\[Your .*?\]
\[Director .*?\]
\[Company .*?\]
INSERT .* HERE

Prompt guidelines (system)

Initial email

80–150 words
Specific but generic business topic (scheduling, follow-up, intro)
Realistic subject ≤60 chars
No signatures with fake phone numbers
Sign off with first name only if name provided in mailbox profile (future)

Reply

40–100 words
Reference specific points from incoming body (quote or paraphrase)
Natural continuation, not sales pitch
Re: subject handling

Content diversity

Technique	Purpose
Temperature 0.8–0.9	Variation
Industry rotation	Context diversity
Thread memory (last 3 bodies)	Avoid repetition in replies
Optional spintax-free rewriting	Structural variation (phase 2)

Mailbox profile (future)

{
  "senderName": "Jon",
  "companyName": "FillCare",
  "title": "Co-founder"
}

AI uses real values instead of inventing or placeholdering.

Failure handling

Failure	Action
3 validation failures	Skip send slot; log `ai_validation_failed`
API down	Retry with backoff; don't send template fallback
JSON parse error	Retry once with stricter prompt

Audit

Store contentVersion and validationResult on WarmupLog for debugging disputes.

Why no links in warmup

Tracking links and URLs are strong spam signals during reputation building. Warmup content should be link-free until placement stabilizes (phase 2: optional benign links).
