For peer-to-peer texting in Canada, we have an option 'Auto-send initial message'. Here are regulations and limitations for this feature.
Customers can use this option to send out the initial message automatically instead of having an agent or a volunteer send it. Given the FCC regulations, users CANNOT use this option to reach out to USA contacts. As per FCC regulations in Canada, a user can Auto-send initial message only to Canadain contacts regardless of the contacts opting in or not to receive the texts, without breaching the regulations.
