Relating to political advertising distributed or broadcast as part of a mass text message campaign.

HB 3386 defines "mass text message campaign" as sending political texts (supporting or opposing candidates, parties, or measures) to multiple recipients when costs exceed basic tech expenses like hardware and bandwidth. The bill adds these campaigns to Texas's definition of "political advertising," requiring them to follow existing disclosure rules for other political ads. It applies only to text campaigns sent on or after September 1, 2025, with older campaigns governed by previous laws. This change ensures political text messaging is treated consistently with other advertising methods under election law.
