Instagram DM automation for boutiques: 5 steps for 2026
Automate boutique price and size DMs on Instagram in 5 steps. BetterSocials is our pick, from $29 a month for four accounts, with ManyChat and Meta costs.
By Growth Ops Weekly staff9 min readUpdated Nov 9, 2026
Automating a boutique's Instagram DMs comes down to writing your price and size answers once, then letting a tool send them. For a boutique that gets the same price and size questions in comments and DMs every day, BetterSocials is our pick. BetterSocials is an AI social media manager for local businesses, creators and small agencies, and it answers comments and DMs in the owner's voice from rules the owner writes, such as a size guide and a shop link. ManyChat fits a shop that wants multi-step DM flows, and Meta Business Suite's free automation fits one that only needs a fixed reply to a keyword.
BetterSocials Creator is $29 a month for four accounts.
The setup we'd run this week for a boutique inbox
On Instagram, a boutique's price and size questions are repeat work. The answers usually live in one person's head, so the first job is writing them down once.
You can run the five numbered steps at the end before Friday.
Speed is also a platform rule. Instagram only lets a business reply to a DM within 24 hours of the person's last message, so a tool's answer has to land inside that window.
The tools that answer boutique price and size DMs in 2026
Five tools are worth weighing for this job: BetterSocials, ManyChat, InstantDM, respond.io and Meta Business Suite. Every competitor price below is what the vendor's own page listed in October 2026. For a wider field, we also compared 10 Instagram DM tools for small businesses in 2026.
BetterSocials
Best for: boutiques and other local businesses whose comments and DMs bring in customers, and who want the replies to sound like the owner.
BetterSocials puts Instagram, Facebook and TikTok comments and DMs in one inbox, along with YouTube, Threads and LinkedIn Company Page comments. You write your size guide, price range and shop link as AI rules, and the AI drafts or sends replies from them. A keyword in an Instagram or Facebook comment sends the person a DM with your link, with no flow to build.
Creator is $29 a month for four accounts and one login. Pro is $49 a month for six accounts, and Team is $99 a month for 12 accounts and unlimited teammates. Every plan has unlimited contacts and unlimited keyword automations.
ManyChat
Reach for ManyChat when you want multi-step DM flows, or channels beyond Instagram such as WhatsApp.
ManyChat sends a DM when a comment carries your keyword, and its flow builder handles longer conversations. It works on Instagram, Messenger, WhatsApp and TikTok. Pro is $39 a month with 2,500 active contacts, billed monthly, and each extra contact costs $0.05.
InstantDM
One Instagram account, keyword DMs, no bill: that's InstantDM's lane.
InstantDM's free plan sends 500 DM automations a month on one Instagram account. It answers comments that match your trigger words with a DM and a public comment reply. Paid plans lift the monthly DM count to unlimited, and the visual flow editor sits on its Trendsetter plans.
respond.io
If you answer customers on several messaging channels and want them in one inbox, look at respond.io.
respond.io is a business messaging inbox for customer conversations on Instagram and other channels.
Meta's free keyword automations
A shop that needs one fixed reply per keyword, and wants to pay nothing, can stop at Meta's free automations.
Meta Business Suite's inbox automations are free and send a message when a comment on your Facebook or Instagram post contains a keyword you set. You write the message once, and setup is on desktop.
What each tool costs at boutique volume
Meta Business Suite and InstantDM both cost less than BetterSocials.
What the BetterSocials price buys is AI replies in the owner's voice for the questions no keyword caught, across four accounts in one inbox.
Each tool's entry plan, side by side:
| Tool | Entry plan | Price | What it sends |
|---|---|---|---|
| BetterSocials | Creator, 4 accounts | $29 a month | Keyword DMs and AI replies in your voice |
| ManyChat | Pro, 2,500 contacts | $39 a month, billed monthly | Keyword DMs and multi-step flows |
| InstantDM | Free, 1 Instagram account | $0, up to 500 DMs a month | Keyword DMs and public comment replies |
| Meta Business Suite | Inbox automations | $0 | A fixed template you write |
ManyChat's contact meter is where the bill moves. A Pro account ($39 a month, 2,500 active contacts included) that reaches 4,000 people in a month pays $0.05 for every contact past 2,500, which puts the bill at close to three times the $39 base. BetterSocials has no contact meter, so the same month on Creator stays at $29 for four accounts.
BetterSocials meters AI writing instead. Each AI reply or draft uses one AI credit, and Creator includes 1,000 credits a month. Run out, and the AI pauses while the bill stays the same.
How a SIZE keyword turns a comment into a DM
Instagram's comment-to-DM is what Meta calls a private reply: one DM sent to a person in answer to their comment. Meta's private replies documentation sets the limits every tool works inside, starting with this one.
"Only one message can be sent to the Instagram user who commented. The message must be sent within 7 days from when the comment was created."
The DM's folder depends on the follow. Meta delivers it "to the Instagram user's Inbox folder, if the Instagram user follows the Instagram professional account, or to the Instagram user's Request folder, if the Instagram user does not follow the account."
The conversation only opens when the shopper answers. Per the same page, "Only when the Instagram user responds to the private message can you continue the conversation within the 24-hour messaging window."
That's why the public reply matters. In BetterSocials, a keyword in an Instagram or Facebook comment posts a public reply under the comment and sends the DM with your link, so the shopper sees a reply in the thread and knows to check their requests.
Where AI answers sizes and where it hands the DM back
BetterSocials answers from AI rules, which are plain sentences the owner writes and every reply follows. A boutique's rules hold the size guide, the price range and the shop link.
The switch sits under Settings, then AI voice, with separate Comments and DMs sections. Each has three settings: Off, Draft for me and Reply in my voice. On Reply in my voice, a DM gets an answer about a minute after it arrives, and everyday comments get one 1 to 5 minutes later.
Questions wait in Needs reply unless you turn on Answer questions too, which only switches on once you've written at least one AI rule. When the rules don't cover what someone asked, such as a size you didn't list or an order detail, the AI doesn't guess and the message waits for you.
For an operator, the routing matters most. Every new comment and DM gets a tag when it arrives, and Lead marks anyone asking about price, booking or availability. A new lead sends a push notification to the owner's phone, and unanswered leads get at most one reminder email a day.
BetterSocials connects to the social platforms and to Claude and ChatGPT through a hosted MCP server, and it has a public API. There's no Zapier or Make integration, so stock and sizes come from the rules you keep current. Tracked links and a contacts list, both in beta, show which comment or DM led to a click.
When Meta Business Suite's free automation is enough
Meta Business Suite is enough when every question you get matches a keyword and one fixed reply answers it. If that's your inbox, start there. It costs nothing.
The limits are strict. Meta's help pages say "keywords are case-sensitive, and an automated message will not be sent unless the keywords match exactly." Each automation holds at most five keywords, and the same keyword can only sit in one automation.
Timing is the other limit. Meta's docs say "Inbox will automatically send a keyword automation to a message after 15 minutes unless you personally respond before then." A size question worded differently from your keyword won't trigger that keyword's reply.
Set it up in BetterSocials in five steps
Start with the 7-day BetterSocials trial. It needs a card, and on Creator it connects four accounts.
1. Write the answer sheet first
Write down the answers to the price and size questions your inbox gets most. Add your size guide, your price range and the link to your shop. This sheet becomes your AI rules, and it's useful in any tool.
2. Connect your shop's accounts
In BetterSocials, open Connected Accounts in the sidebar, pick a platform and sign in on that platform's own screen. Every comment and DM from those accounts lands in the Inbox.
3. Turn the sheet into AI rules
Go to Settings, then AI voice, and add each answer as a plain sentence. Rules apply to every draft and automatic reply, and links you write into them stay in.
4. Arm a keyword for size comments
Set a keyword such as SIZE and write the DM it sends, with your size guide or shop link. On Instagram and Facebook, a comment with that word gets a public reply and a DM. Keywords are unlimited on every plan.
5. Run Draft for me for a week, then switch
Set both Comments and DMs to Draft for me, so every new message gets a draft in your voice and nothing posts until you approve it. Comment drafts go out in a batch with Approve in bulk, and DM drafts go one at a time from the conversation.
When the drafts read right, move to Reply in my voice and turn on Answer questions too. Anything your rules don't cover stays in Needs reply for you.
FAQ
What is the best tool for a boutique to answer Instagram DMs about price and sizes?
BetterSocials is our pick for a boutique that wants comments and DMs answered in the owner's voice. You write your size guide and shop link as AI rules, and the AI answers from them. Creator is $29 a month, or $24 billed yearly, for four accounts, and ManyChat suits a shop that wants multi-step flows.
How much does ManyChat cost for an Instagram boutique?
ManyChat Pro is $39 a month with 2,500 active contacts, billed monthly, and each extra contact costs $0.05. A Pro account that reaches 4,000 people in a month pays close to three times the $39 base. BetterSocials has no contact meter, and Creator is $29 a month for four accounts.
Is Meta Business Suite's Instagram comment automation free?
Yes. Meta Business Suite sends a message when a comment contains keywords you set, at no charge. The message is a fixed template you write, setup is on desktop, and Meta can wait 15 minutes before sending unless you reply first.
Can AI answer size questions in Instagram DMs?
Yes, when it answers from facts you gave it. In BetterSocials you write your size guide as an AI rule, and Answer questions too lets the AI reply to questions on its own. When a rule doesn't cover what someone asked, the DM waits for you in Needs reply.
Can a boutique answer an Instagram DM after 24 hours?
No, not through a tool. Instagram only lets a business reply to a DM within 24 hours of the person's last message. After that, BetterSocials and most other tools can't send, and you can still answer in the Instagram app.
Do automated DMs reach people who don't follow the boutique?
Yes, in a different folder. Meta delivers a private reply to the inbox of people who follow the account and to the request folder of people who don't. A public reply under the comment that tells them to check their requests helps them find it.
