Can a prompt replace Mailchimp?
Newsletters & publishing — email marketing
Exhibit tracking slip
Verdict
A small-list campaign sender — contacts, segments, a Markdown-to-HTML composer, compliant unsubscribe handling — is a real weekend build. What doesn't come with it is Mailchimp's actual moat: inbox deliverability earned over years of sending reputation, which no amount of personal engineering can shortcut.
Exhibit A — The prompt
Received on30.07.2026Build a small-list email campaign tool: contacts with tags and custom fields, CSV import and export, and segments defined as saved filters (has a given tag, joined after a date, opened the last campaign). Write campaigns in Markdown, rendered into one clean single-column HTML email with an automatically generated plain-text alternative. Send through a real transactional email API (Amazon SES or similar) with throttling and a per-recipient status; wire up bounce and complaint webhooks to automatically suppress those addresses going forward. Bake compliance in rather than bolting it on: an unsubscribe link and your postal address in every footer, a List-Unsubscribe header, and double opt-in on the public signup form. Make open tracking a per-campaign toggle, off by default. Show a campaign report with sent, bounced, and unsubscribed counts.
Do not build a drag-and-drop template editor, visual automation journeys, or e-commerce integrations — those are real, separate products. Be blunt in the README: inbox placement is earned through sending behavior over time, not configured. Document SPF, DKIM, and DMARC setup, and warm up sending volume gradually on a new domain.Opening prefills the prompt — press enter to run it.
Exhibit B — What you lose
- B.1 deliverability backed by an established sending reputation
- B.2 the drag-and-drop template editor
- B.3 visual automation journeys
- B.4 e-commerce integrations
- B.5 dedicated support
Prior art
Exhibit C — Why people still pay: deliverability/compliance/integrations
Email is business-critical, and deliverability problems are expensive to diagnose and fix — people pay so inbox placement is someone else's ongoing responsibility.
Questions
Can I import my existing Mailchimp audience?
Yes — Mailchimp exports your contacts, tags, and custom fields to CSV, which imports directly here. Automation journeys and templates don't transfer; that logic has to be rebuilt from scratch.
Will it work on my phone?
The admin view is a plain web page, usable on a phone for a quick check, but the composer isn't optimized for a small screen and there's no dedicated app.
What does it cost to run?
Hosting, a domain, and a database, typically a few dollars a month, plus per-email sending costs on the transactional API — often well under Mailchimp's tiered pricing at small list sizes.
What's the one thing that doesn't survive the rebuild?
Sending reputation. Mailchimp's shared and dedicated IPs carry years of established trust with inbox providers; a brand-new sending domain starts at zero and has to earn that trust the same slow way, regardless of how good the code is.
