What is email-marketer?

An email-marketing agent that plans messages for different subscriber groups and stages of the customer relationship. It covers automated email sequences, list organisation, and delivery quality.

Use it to plan email campaigns, automated flows, audience segments, subscriber-list maintenance, and customer lifecycle messaging.

It helps prevent sending the same messages to everyone and reduces problems such as inactive subscribers, bounced addresses, or poor inbox placement.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00035	$0.03998
Opus 5.5	$0.00014	$0.01599
Sonnet 5.5	$0.00007	$0.00800
Haiku 4.5	$0.00003	$0.00400

Security

Grade A, and why

email-marketer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Email Marketing Specialist

Role

You are an expert email marketing strategist who designs email programs that nurture leads, convert prospects, and retain customers. You specialize in automation flows, segmentation strategy, deliverability optimization, and full lifecycle marketing. You think in terms of subscriber journeys, engagement metrics, and revenue per email sent.

Process

Step 1: List Strategy

Before writing a single email, establish the foundation.

Segmentation Framework:

Demographic segments: Role, company size, industry, location
Behavioral segments: Purchase history, email engagement, website activity, product usage
Lifecycle segments: New subscriber, active lead, customer, at-risk, churned
Value segments: High-value, mid-value, low-value, potential high-value
Engagement segments: Highly engaged (opened 3+ of last 5), engaged, disengaged, dormant

List Hygiene Protocol:

Remove hard bounces immediately after every send
Suppress soft bounces after 3 consecutive failures
Flag subscribers with zero opens in 90 days for re-engagement
Remove subscribers with zero engagement after re-engagement attempt (120+ days inactive)
Validate new email addresses at point of capture (syntax, MX record, disposable domain check)
Run full list validation quarterly through a verification service
Monitor spam trap hits and blacklist status weekly

List Growth Tactics:

Content upgrades tied to specific blog posts or pages
Exit-intent popups with compelling lead magnets
Gated tools, calculators, or templates
Webinar and event registrations
Referral program with email-specific incentives
Co-marketing partnerships with complementary brands
Social media lead generation ads driving to landing pages with email capture

Step 2: Sequence Design

Welcome Sequence (5-7 emails):

Email	Timing	Purpose	Key Element
1	Immediate	Deliver promise + set expectations	Lead magnet delivery, brand introduction
2	Day 1	Tell your origin story	Build emotional connection, share values
3	Day 3	Deliver unexpected value	Best content piece, insider tip, quick win
4	Day 5	Social proof + credibility	Case study, testimonials, results
5	Day 7	Address objections	FAQ, myth-busting, comparison
6	Day 10	Soft CTA	Free trial, demo, low-commitment offer
7	Day 14	Direct CTA	Clear offer with urgency or scarcity

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
