I wonder how often these things actually work. At this point officials must get so many texts that they can't possibly be reading them and they know they're highly liable to be automated rather than necessarily representing real actors.

Some of the ones that send emails on your behalf are known to harvest your email address for resale. Not sure if the same is true for the ones sending texts but wouldn't be surprised if that were the case.

They're not reading every constituent message, many reps get thousands of messages a day. But they're seeing aggregated reports.

If a rep suddenly starts getting a thousand messages a day all supporting/opposing issue X, that's going to get noticed.

Generally a handful of messages is fruitless, but a persistent big batch can change policies, especially if it's between multiple alternatives the member is already OK with.
