For ActionKit integrations, the "Subscribe imported people to text messages" option is now only available on accounts with a number that texts subscribed people, since ActionKit doesn't record text message opt-outs and the option could subscribe people who had opted out. While the option is on, a warning now explains that the first import subscribes every mobile number, hourly syncs subscribe new and updated people, and people who opted out in another tool will be subscribed again. Integrations that already have it on can still turn it off from their settings page.
