Instagram DM automation:answer comments in private.

What Instagram DM automation is

Answering every "price?" comment by hand does not scale during a launch. Automation ties it to a rule: when the keyword appears in a comment, the person gets a private message, and you only talk to the people who reply.

Two different automations are often mixed up. One answers a comment with a private message; the other replies to incoming DMs. In the panel they are set up on separate screens.

How comment-to-DM works

• Matching ignores case; the keyword only has to appear somewhere in the comment.
• A rule can run on Instagram, Facebook or both.
• Rules run on every post; the screen has no option to limit a rule to a single post.
• The public reply is independent of the DM: the comment is answered even if the message fails.
• The comment and its post also appear in the inbox of the social media management tool, where you can reply by hand.

Setting up an auto DM rule, step by step

1. 1Connect your Instagram account in the panel; the connection requires a professional account.
2. 2Open a new rule on the Comment to DM screen, or start from one of the ready-made templates.
3. 3Name the rule and choose the platform: Instagram, Facebook or both.
4. 4Add keywords one by one; any one of them in a comment triggers the rule.
5. 5Write the message template. Placeholders cover the person's name, the coupon, a link and the post link.
6. 6Optionally add a public reply, a coupon code and the link you want to send people to.
7. 7Set the cooldown; the default is 24 hours.

Meta's rules: 7 days, one message, 24 hours

Meta sets the limits, not the tool. These rules apply to every Instagram automation tool; a campaign that ignores them finds out late that messages it counted as sent never reached anyone.

• Only one private reply can be sent to a commenter, within 7 days of the comment. Source: Meta's private replies documentation.
• If the person replies, a conversation opens; a follow-up can only be sent within 24 hours of that reply.
• If the person follows your account the message lands in their inbox; otherwise it lands in message requests.
• For incoming DMs the standard window is usually 24 hours, and up to 7 days after a first message from a click-to-Direct ad. Source: Meta's messaging policy.

The app side needs permissions too: comment management for comments and message management for DMs. Apps that serve accounts they do not own pass Meta's review for these; the conditions are in the messaging API documentation.

Auto-replies to incoming DMs and after-hours mode

DMs and comments from Instagram and Facebook land in the panel's inbox. If you turn on auto-reply, AI reads the message and the last few messages from that person, drafts a reply and sends it.

• Auto-reply is off by default and is switched on separately for DMs and for comments.
• With "only outside working hours", your team answers during the day and the system at night.
• With handoff on, anyone who asks for a person gets your saved WhatsApp or phone number; with no number saved, nothing is sent.
• The same person never gets a second auto-reply within 10 minutes, so two accounts cannot loop.
• If no reply can be drafted, nothing is sent and the conversation waits for you.

Where people who get a message are saved

When the message is delivered, the person is added to the lead list with the "Comment to DM" source. You follow the lead to a sale in the CRM.

• The screen shows 30-day counters: active rules, messages sent, triggers and leads.
• Leads who left contact details are counted separately.
• If a message fails, no lead is created and the reason is kept in the event log.

What the automation does not do

These are the limits to know before you buy. Each comes either from Meta's rules or from what the product covers today.

• No multi-step flows, buttons or follow-up sequences; a rule sends one text message.
• Rules are triggered by comments only; a keyword in a DM does not trigger a rule, DMs are handled by auto-reply.
• A fixed opt-out line is added to the end of each message. Today that line is in Turkish only.
• No tool can guarantee that someone who does not follow you accepts a message request.
