What Colorado asks of a business with a website

Before your website goes live, it helps to have the basics of the business in order.

• Colorado trade names are filed with the Secretary of State (not a county), and they must be renewed periodically. Official source
• Newsletters and promotions sent from your business email must include a working way to unsubscribe (16 CFR Part 316). 16 CFR Part 316

Each business is different; this is general information, not legal advice.
