What e-commerce customers DM about on Instagram

Before you set up automation, look at what actually lands in your inbox. For most stores on Instagram, it breaks down like this:

Product questions (the biggest share)

• "Is the [product] available in [size/colour]?"
• "What is the material / how does it fit?"
• "I ordered a medium before — should I size up for this style?"
• "Is the [sold-out item] coming back?"

Order and shipping questions

• "I ordered [X] days ago and haven't received a tracking number"
• "How long does delivery take to [country]?"
• "Can I change my delivery address?"

Return and exchange questions

• "What is your return policy?"
• "I received the wrong item — what do I do?"
• "Can I exchange for a different size?"

Pre-purchase questions

• "Do you ship internationally?"
• "Is there a discount code available?"
• "What's the difference between [product A] and [product B]?"

Automation can answer all of these. The real question is which type of automation fits each one best.

Setting up DM automation for e-commerce

What to put in your AI knowledge base (ReplyMind)

When you connect ReplyMind, fill in your business details fully. This becomes the AI's source of truth for every product question:

Products section: List each product (or category, for large catalogues) with the key details: materials, sizing advice, care instructions, what it pairs with.

Shipping section: Local and international shipping times, the carriers you use, tracking, and cut-off times for same-day dispatch.

Returns section: Your return window, conditions (unworn, tags attached), how to start a return, and refund vs exchange rules.

Availability section: How to check stock, restock timelines for popular items, and your waitlist process if you have one.

Promotions section: Current discount codes, loyalty programme details, referral scheme.

With this in place, the AI answers any product question accurately. You don't need to build a separate flow for each one.

Comment-to-DM for product posts

For every product launch post or Reel:

Caption CTA: "Want to know if [product] is available in your size? Comment SIZE below and I will DM you instantly."

When someone comments, your DM automation fires: "Hi! The [product] is currently available in S, M, L, and XL. We are low on M — ready to order? Here's the link: [URL]"

This turns post engagement straight into sales conversations. The customer never has to leave Instagram to find your website.

Keyword flows for high-frequency consistent questions

For questions with fixed answers, keyword flows are fast and precise:

RETURN trigger → send your full return policy + link to return form SHIPPING trigger → send shipping times by region + tracking info DISCOUNT trigger → current discount code or loyalty programme info RESTOCK trigger → general restock process and where to sign up for notifications

What still needs a human

Some situations genuinely need human judgement:

• Disputed orders or customer complaints
• Unusual returns (an item arrived damaged)
• Large or custom orders
• A customer who is clearly upset

Set your automation to hand these off: "I want to make sure this is handled properly — I'm passing this to our team right now and someone will reach out within [timeframe]."

The result of DM automation for e-commerce

Without automation: questions arrive, sit for hours, and customers move on. A shopper who can't get a quick answer often buys from a competitor instead.

With automation: every question gets an instant, accurate answer. A customer who asks about sizing gets sizing advice right away — and is far more likely to finish the purchase.

Automation doesn't replace customer service. It handles the routine, predictable questions, so your team keeps its time and energy for the ones that truly need judgement.
