Colorlib Email Templates is a collection of responsive HTML email designs for services such as Mailchimp and other email delivery platforms. It is intended for people creating campaigns that need to render across common email clients, and the catalogue entry provides instructions for using or customizing the templates.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01729 | $0.01729 |
| Opus 5.5 | $0.00692 | $0.00692 |
| Sonnet 5.5 | $0.00346 | $0.00346 |
| Haiku 4.5 | $0.00173 | $0.00173 |
Grade A, and why
email-templates CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Repository purpose
Free, responsive HTML email templates published by Colorlib. 28 numbered template folders, served as-is to end users.
All 28 templates are MJML-sourced. Each N/index.html is a build artifact generated from src/N.mjml. Never edit N/index.html directly — edit the source.
Note: the global
~/.claude/CLAUDE.mddescribes a Bootstrap-upgrade workflow for Colorlib website templates. That workflow does not apply here — these are email templates (table-based HTML, no Bootstrap, no jQuery, no SCSS).

├── dev.mjs # dependency-free static server + SSE live-reload
└── screenshots.mjs # render N/index.html → screenshots/NN.jpg for the README
1/, 2/, ..., 28/ # build artifacts — each has index.html (+ images/ where used)
screenshots/ # README gallery thumbnails, regenerated by npm run screenshots
index.html # gallery index linking to all 28 templates
Commands
npm install # one-time, installs mjml + chokidar + playwright-core
npm run build # compile every src/*.mjml → N/index.html
npm run dev # watch src/, live-reload at http://localhost:3000/ (--no-open, PORT=)
npm run screenshots # re-render README thumbnails (needs Google Chrome installed)
npm run dev opens the gallery index, which links to all 28 templates. Saving src/N.mjml rebuilds only that template; saving anything in src/partials/ rebuilds everything.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
