THE EMAIL TAX

How email marketing pricing traps you

Every email tool charges by subscriber count. Grow your list, grow your bill. Succeed at marketing, get punished for it.

HOW IT WORKS

The email pipeline

Every email flows through a simple, transparent pipeline you control end-to-end.

1

Template

React Email component with your brand — colors, fonts, logo. Lives in packages/emails/.

↓
2

Claude Code Drafts

Tell Claude what to send. It personalizes subject lines, body copy, and merge fields from your CRM data.

↓
3

Resend Delivers

Resend API sends via Amazon SES. SPF, DKIM, DMARC pre-configured. Deliverability on par with any major provider.

↓
4

Webhooks Track

Opens, clicks, bounces, complaints — Resend sends events to your resend webhook. Every interaction lands in your events table.

↓
5

Sequence Engine Schedules

Netlify scheduled function checks sequences every hour. Sends the next email in the drip when the delay is met. Fully automatic.

↓
6

Neon Stores Everything

Every send, open, click, and reply is stored in Postgres. Query anything: "which emails got the most clicks last month?"

FAQ

Common questions

Resend's free tier gives you 3,000 emails/month and 100 emails/day. Their pro tier ($20/mo) gives you 50,000 emails/month. Compare that to Mailchimp, which charges $350/mo for the same volume — and still limits automation to their Standard plan.
Resend runs on Amazon SES — the same infrastructure that delivers billions of emails daily. You get SPF, DKIM, and DMARC configured automatically. Deliverability is on par with any major provider. The difference: you're not sharing IP reputation with thousands of other senders on a free plan.
Yes. Export your audience as CSV from Mailchimp, then tell Claude Code 'import these subscribers.' It maps the fields to your Neon contacts table — email, name, tags, signup date, engagement history. No lost data, no manual field mapping.
No. SoloStack uses React Email for templates — but you don't write the code. Tell Claude Code 'create a welcome email with our brand colors and a CTA button' and it builds the template. If you want to tweak it, Claude handles the edits too.
Templates live in packages/emails/ as React Email components. They use your brand system automatically — same colors, fonts, and style as your website. Claude Code can create, edit, and preview templates on demand. No drag-and-drop editor needed.
Yes. Tell Claude Code 'send version A to 50% and version B to 50%' — it splits the list, sends both variants via Resend, and tracks opens/clicks via webhooks. After a set period, it shows you the winner with statistical significance. No $99/mo plan required.
