What the sources say

The Montana sources reviewed for this page do not expressly establish a general SMS or MMS rule. They are included because related telemarketing, do-not-call, privacy, or consumer-protection requirements may still matter to a messaging program.

Montana Consumer Data Privacy Act as amended by SB 297

#

How this authority relates to messaging

This source is relevant to the broader program, but the reviewed text does not expressly establish general SMS or MMS coverage.

What the source establishes

  • Rights include access, correction, deletion, portability, and opt-out of sale, targeted advertising, and profiling; businesses must provide clear means to exercise rights.

Limits and important context

  • Montana DOJ says the amended law applies to businesses conducting business in or intentionally targeting Montana, with thresholds reduced to 25,000 consumers, or 15,000 where more than 25% of revenue comes from sale of personal data. Important because Montana’s lowered thresholds make coverage more likely for midsize messaging programs and vendors than under earlier state models. The threshold change is the key design signal. Programs that previously screened Montana out may now be covered. Amended law effective October 1, 2025. Strongest surfaced official source is the Montana DOJ guidance page. Amendments effective October 1, 2025 lowered thresholds and removed the cure period; $7,500 per violation.

Facts that may change the result

  • Does the organization meet Montana’s amended privacy-law thresholds?
