Instagram DM automation for service businesses
How to answer Instagram DMs automatically and honestly: what the platform requires, the 24-hour window, what an AI should do with a DM about a price or a booking, and what to keep human.

Instagram DM automation lets a business reply to DMs instantly from the same AI and knowledge that answers texts, book appointments in the DM thread, and hand off to a person when the rules say so. It requires an Instagram professional account connected to a Facebook Page, it works within Instagram's messaging windows, and it should say plainly that it is an assistant. For salons, med spas, fitness studios and anyone whose customers find them on Instagram, the DM is the front door.
Why DMs matter more than calls for some businesses
A med spa's new clients find it on Instagram, look at the work, and DM "how much for lip filler". They do not call. The DM arrives at 10pm, the owner sees it in the morning, and by then the client has DMed two other clinics. Answering DMs in seconds is the difference between the consult and the silence.
What the platform requires
An Instagram professional account (business or creator) linked to a Facebook Page, and a messaging platform approved to use Instagram's messaging API. The business connects the account once; messages then flow into the platform's inbox and replies go out as the business. Instagram's rules and features change; check the current requirements when you connect.
The messaging window
Instagram allows a business to reply freely within a window after the customer's last message (currently 24 hours for standard messages). Outside the window, the business generally cannot start or continue a conversation except in specific permitted cases. In practice this means: reply fast, book in the thread, and if you need to follow up days later, ask for a mobile number and consent to text during the conversation.
What the AI should do with a DM
A price question: answer from the approved price list, and offer to book the consult. No guessing.
A booking request: offer real slots in the thread and confirm. Ask for a mobile number for the confirmation and reminders, with consent.
A question about a treatment's suitability: hand off to a provider. Not answered in a DM, not even gently.
A comment reply or story reply: these arrive as DMs too. Treat them as a conversation start.
A compliment or a general chat: a warm, brief reply, and leave it there.
What to keep human
Complaints. Anything clinical. Influencer and partnership enquiries. Anything that mentions a bad experience. The rules for DMs are the rules for every other channel: fixed handoffs, run before the AI generates anything.
Say it is an assistant
"Hi! This is Glow Aesthetics' assistant. I can book consultations and answer questions about treatments and prices." Honest, and it sets expectations. A DM that pretends to be the owner and then cannot answer a clinical question reads badly.
One thread with everything else
The DM lands in the same inbox as texts, the client's record is beside it, and when they text next week the DM history is there. The person who takes the handoff sees the whole thing. This is the point of connecting Instagram to a unified inbox rather than a DM-only tool.
Frequently asked questions
Can it reply to story mentions and comments?
Story replies and mentions arrive as DMs and are handled the same way. Public comments are separate; some platforms can reply to comments or move the commenter to a DM.
Does it work for an account managed by several people?
Yes. That is the point: the DMs are in the shared inbox, assigned, with no one person's phone as the bottleneck.
What about Instagram's own automated replies?
Instagram offers simple saved replies and away messages. They do not book, answer from your knowledge, or hand off. Use the platform's automation for the front door and turn the built-in ones off to avoid double replies.
What Frontiva does here
In Frontiva, Instagram DMs are received, answered by the AI from your approved knowledge with the same guardrails as SMS, and replied to by staff in the unified inbox, and comments can trigger a private-reply acknowledgment. A self-serve connect flow waits on Meta's app review, and the AI does not book inside a DM yet. The med spa and salon pages show where DMs fit.
Instagram is one channel of several here, in the same inbox as the rest. See what is an AI receptionist for what answers them.
