Documentation Overview

Newsletter Growth MCP

Growth loops, welcome sequences, and monetization readiness for the only audience you actually own.

Disclaimer. Practitioner frameworks; thresholds are ranges, not guarantees. The author runs paid per-click sponsorships on her own list — these are the numbers sponsors actually pay on.

Why This Exists

Platform followers are rented; the list is owned. But most creators (and their AI agents) treat the newsletter as a broadcast afterthought: no welcome sequence, no growth loop, monetization guesses based on list size instead of engagement.

The house rule: engagement monetizes; size impresses. A 520-person list at 43% opens out-earns a 10k list at 12%.

Tool	What it returns
`get_growth_loop`	5 growth loops (lead magnet, social repurpose, cross-promo, referral, sponsorship swap) with when each wins and its failure mode
`get_welcome_sequence`	The 6-email architecture: deliver → receipt → quick win → segment → soft offer → close
`audit_subject_line`	PASS/NEEDS WORK: truncation length, spam phrases, fake Re:, specificity
`interpret_list_metric`	Healthy/warning ranges + diagnostics for opens, clicks, growth, unsubs, replies
`get_monetization_readiness`	Given your list size + engagement: readiness verdicts for own product, per-click sponsorships, flat placements
`get_full_pack`	Everything in one payload
