What common digital marketing pitfalls lead to costly regulatory fines?

The most frequent—and expensive—mistakes are hidden endorsements, misleading price/“sale” claims, non-compliant email/SMS consents, and sloppy contests/sweepstakes. Add recurring-billing problems (unclear free trials, hard-to-cancel “negative options”) and you have a recipe for complaints and enforcement. Fix the basics: disclose plainly, substantiate claims, capture/ honor channel-specific consent, and publish complete promotion rules with records to prove it.
