Instagram auto reply: how to set it up, with message examples

If you manage an Instagram business account and answer the same customer questions often, auto replies can handle common messages while you choose what to automate. Meta’s options mostly send fixed text; compare them with HeyMark’s keyword rules and AI to choose how you will answer recurring questions. Claims about Instagram and Meta are based on their official documentation, checked September 25, 2026.

What Instagram includes

Meta offers them in two places, the Instagram app and Meta Business Suite, and almost all of them send fixed text:

Sources: FAQs, Meta Business Suite automations and AI auto replies. Meta describes Business Suite as a free platform, and its automations work with Instagram business accounts connected to it. Saved replies aren’t automatic: they’re shortcuts for typing faster.

If a conversation appears in Instagram but not in Meta Business Suite Inbox, see what to check when Instagram messages are missing there.

How to set up auto replies in Meta Business Suite

1. Open Automations

   In Meta Business Suite on desktop, go to Inbox and click Automations.

2. Pick a template

   Click Create automation and choose the one you need: auto reply, away message, frequently asked questions or custom keywords.

3. Write the reply

   Follow the on-screen steps, like picking the channel and writing the text, then save. It may take a few minutes to show up.

4. Turn it on, edit it or turn it off

   The toggle under Status turns it on or off, and Edit changes it.

The steps come from Meta’s Business Help Center.

What HeyMark adds

Meta’s tools cover a greeting and four questions. When people also message you on TikTok, or when you want someone to carry the conversation, HeyMark adds:

• Keyword DM rules on Instagram, Facebook and TikTok, with up to 20 keywords per rule (Meta Business Suite allows up to 5). They come with every plan and spend no credits.
• AI for what no rule covers. AI DM automation writes each reply in your brand’s voice and uses 1 credit per reply. More in AI chatbot for Instagram DMs.
• Comment rules, with a public reply and a DM for anyone who comments a keyword. On a post automation, if that DM can’t be sent, a fallback public reply goes up instead. The details are in Instagram DM automation.
• One inbox for Instagram, Facebook and TikTok messages, where you reply by hand, pause the AI and see what was escalated to a person. More in unified social inbox.

Instagram auto reply message examples

Three kinds of business, with the keywords that trigger each reply:

All six answer the question and leave a next step: a link, a phone number or a question. The keywords include the variants people actually type, singular and plural. And the clinic doesn’t diagnose by message: health questions go to a person. For the coffee shop, an away message rounds it out: “We’re closed right now. We’ll reply tomorrow from 8 a.m.”

Can you auto reply to new followers on Instagram?

It depends on the tool and your account’s eligibility. Manychat offers Follow-to-DM in beta, with Meta deciding which accounts can use it. Following an account alone does not open the messaging window: the person must reply to the opening message or interact with a button that is not a link. This is a specific beta option, not a feature available to every account or a HeyMark automation.

For HeyMark’s DM rules, invite people to write first. A story highlight or a pinned post saying “DM us ‘hours’” gives them a clear next step, and your rule replies. Standard Instagram messaging allows replies within 24 hours of their message. A private reply to a comment is a separate flow: it allows one private reply within 7 days of the comment.

Why Instagram auto replies stop working

These are the causes Meta documents in its help on automations and the pages linked below:

• The account isn’t a business account, or it isn’t connected. Meta Business Suite automations work with Instagram business accounts connected to Business Suite.
• Message access is off. In the app, under Messages and story replies, then Message requests, the Connected tools section has the option to allow access to messages. If it’s off, you can only view and send messages from Instagram: neither Business Suite nor a connected tool like HeyMark can reply.
• The keyword doesn’t match exactly. In Business Suite, keywords are case-sensitive, and each keyword can only be used in one automation.
• Another automation goes first. If your away message is on and someone sends a keyword, Meta sends the away message, not the keyword reply.
• You replied first. Meta sends a keyword reply after 15 minutes unless you respond yourself before then.
• You turned on Meta Business Agent. Your existing automations, like the away message, are paused.
• The window closed. A connected tool has 24 hours from the person’s last message to reply, and 7 days from a comment to send the private message.
• Your business is in Europe or Japan. Meta warns that some organic messaging features for businesses there will be unavailable.

If messages arrive but Instagram does not alert you to new ones, see what to check when notifications are not coming through.

When Meta’s tools are enough

If what people ask fits in a greeting, an away message and four FAQs, Meta’s tools are enough. The same goes if WhatsApp matters to you, since Business Suite covers it and HeyMark doesn’t work with WhatsApp. And for long flows with branches and conditions, a chatbot builder like ManyChat goes further than either.

HeyMark makes sense when people also message you on TikTok, when one reply needs more than 5 keyword variants, or when you want AI to answer what no rule covers, in the same tool where you schedule your posts.

How to get started with HeyMark

Connect Instagram, plus Facebook and TikTok if people message you there, and create a DM rule for each question that keeps coming up. You can also ask Mark, or Claude or ChatGPT with HeyMark connected. Change what’s in brackets:

Create a brand-wide DM rule in HeyMark for Instagram.

When someone messages me hours, opening hours or what time, reply: "We're open Monday to Friday from [weekday hours] and Saturdays from [Saturday hours]. We're closed on Sundays."

Show me how it looks before turning it on.

Before creating it, your assistant shows you a preview and waits for your approval. Then test it: send “hours” to your brand from another account. Every plan starts with a 7-day free trial.
