Where can SMBs find practical guidance for evolving marketing rules?

Start with primary sources: the FTC (claims, endorsements, email), FCC (TCPA for texts/calls), and your state AG for local rules. In the UK and EU, use ICO/PECR and ASA/CAP for ads, plus EDPB and ePrivacy/GDPR for consent. Subscribe to regulator updates and keep a 2-page internal Marketing Compliance Playbook: required disclosures by channel, approval steps, and records to retain.
