A campaign sender is buildable, but Mailchimp's value is deliverability, templates, compliance, automations, segmentation, ecommerce integrations, and support.

the prompt
Build me a small-list email campaign tool to replace Mailchimp. Requirements:

- Node + Express + better-sqlite3 on my VPS. Admin UI bound to localhost/VPN; only
  the subscribe and unsubscribe endpoints are public.
- Contacts with tags and custom fields, CSV import and export, and segments saved
  as filters (has tag X, joined after date, opened last campaign).
- Campaigns written in Markdown, rendered into one clean single-column HTML email
  with mjml, plain-text alternative generated automatically.
- Send through Amazon SES (keys in .env) with throttling and per-recipient status;
  SES bounce and complaint notifications auto-suppress those addresses.
- Compliance baked in: unsubscribe link and postal address in every footer, a
  List-Unsubscribe header, double opt-in on the public signup form.
- Open tracking is a per-campaign toggle, default off. Campaign report shows sent,
  bounced, and unsubscribed counts.
- One SQLite file holds everything; no telemetry, no third-party trackers.
- Out of scope: the drag-and-drop template editor, automation journeys, and
  ecommerce integrations. One good template, sent well.
- README warning: inbox placement is earned, not coded. Document SPF, DKIM, and
  DMARC setup and tell me to warm up sending volume gradually.

questions
Can AI replace Mailchimp?

Kinda. The core of Mailchimp is buildable in a weekend with the prompt on this page, but there are real gaps: deliverability, template/editor polish. Read the honest list above before committing.

How much does Mailchimp cost?

Mailchimp costs about $20/month (Standard, checked 2026-07-30), which is $240 per year.

What do I lose by replacing Mailchimp?

Honestly: deliverability; template/editor polish; automation builder; ecommerce integrations; segmentation; compliance; support. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Mailchimp?

Yes — Mautic (Open-source marketing automation platform with email campaigns and contact management.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
