Easy Opt-in Methods: Contacts can opt-in to receive texts from you by:

Initial Text Confirmation: When you send a contact their first text, they must reply ok to continue receiving messages. CallingPost automatically prompts them to do this.

No Time Limit for Opt-in: Contacts can reply ok at any time after receiving the initial text.

Opt-Out (Stop): Contacts can text stop to stop receiving messages from you.

Opt-In Again (CPC): Even if a contact has opted out, they can opt back in by texting CPC to 24251. CPC overrides all other commands. Due to FCC regulations, contacts from your group must “Opt-In” to receive text messages from you.
