Email Footer Law Lint

Runs the same checker as our npm package on a Node.js runtime that pip installs for you (nodejs-wheel-binaries) - no system Node.js needed. Your files are checked locally.

Fourteen checks on an HTML email footer: CAN-SPAM postal address and 10-business-day opt-out, CASL's 60-day window, and German 5 DDG, the statute that replaced 5 TMG on 2024-05-14.

Install

email-footer-law-lint file

Node 18+. The same 14 rules as the VS Code extension, from a terminal or CI.

Free

• Check the email template open in your editor against all 14 footer-law rules, every finding carrying its line, its statute and its fix
• --rules lists every rule

With a licence ($29 once)

• Sweep every template in the workspace and write one dated, citable audit report file you can hand to a client or to counsel

email-footer-law-lint --dir ./templates --report html --out report.html

Outside counsel reads one email footer against CAN-SPAM, CASL and 5 DDG at about $300 an hour, and reads it once.
