Quick answerA Facebook Page can send one private Messenger reply to each comment on its posts, within 7 days of the comment. Meta Business Suite offers a free comment-to-message automation with keyword triggers. For richer flows you need a Messenger tool such as ManyChat. It works on Pages only, not personal profiles or groups.
Option 1: Meta Business Suite (free)
- Open Meta Business Suite, then Inbox, then Automations.
- Choose the comment-to-message automation.
- Pick the post, keywords and the message, then save.
Meta changes these menus often. It suits simple one-message replies.
Option 2: A Messenger automation tool
For buttons, multi-step flows or lead capture, use a tool with Messenger support, such as ManyChat, LinkDM or ReplyRush. Compare them in our DM tools roundup.
Doing this on Instagram?
