Can I vibe code Mailchimp?
Email marketing: lists, campaigns, automations, deliverability.
The campaign editor and the subscriber list are easy. The product is not the editor — it's deliverability: warmed-up sending IPs, domain reputation, ISP relationships, bounce and spam handling, and compliance. You can send email from code in an hour; landing in the inbox instead of spam at any volume is the moat, and it isn't something you vibe-code.
Build a lightweight email-list tool for my own small, permission-based audience — and be explicit in the README that deliverability at scale is out of scope and best left to a real provider. Features: a signup form with double opt-in; a subscribers table with tags and one-click unsubscribe (compliant footer); a simple campaign composer that sends via a transactional email API (e.g. Resend or SES); and basic open/click tracking. Warn me clearly about volume limits, SPF/DKIM/DMARC setup, and when I should stop DIYing and move to a dedicated ESP.
A subscriber list with double opt-in and a campaign sender built on a transactional email provider — fine for small, permissioned lists.
- Deliverability infrastructure — IP warming, reputation, ISP relationships
- Automations, segmentation, and a template gallery out of the box
- Compliance tooling (unsubscribe management, regional rules)
- Analytics on opens/clicks without building tracking yourself
- Support when your domain reputation tanks
Anyone can send email; getting it into the inbox at scale is a specialized, ongoing operation. That deliverability infrastructure is the real product, and it's the one part you can't prompt your way to.
A prompt is the first move, not the whole game. Course 01 teaches you to take a prompt like this one to a shipped, working app — reviewing, correcting, and steering the agent the whole way.
