The Facebook Messenger 24-hour rule

Same idea as Instagram, with message tags for a few exceptions.

Updated September 23, 2026 · By the FameChamp team

Quick answerA Facebook Page can message a person for 24 hours after their last message. Outside that window, only messages with an approved message tag are allowed: confirmed event update, post-purchase update, account update and human agent (7 days, human replies only). Marketing outside the window needs paid sponsored messages or opt-in marketing messages.
