A carousel DM is one message with several swipeable cards. Each card has its own image, a short caption and a button, so someone who comments a keyword on your post can browse a handful of products without leaving their inbox.

This guide walks through building one in BlipDM, from choosing the post to switching the automation on.

Before you start

You will need:

  • An Instagram professional account connected to BlipDM.
  • An image for each product, saved as a PNG or JPEG.
  • A link for each product's button, such as a product page or a checkout link.

1. Choose the post

Click New Automation and pick Comment to DM. Under Select your post, choose A specific post to attach the automation to one post, or Any post to run it on all of them.

2. Choose your trigger keyword

Under Choose your trigger keyword, pick A specific keyword and type the word you will ask people to comment, such as SHOP. Or pick Any comment to reply to everyone.

A short, easy-to-type word works best. The Secret to Choosing Instagram Comment Keywords covers what to look for.

In DM Message, switch to the Carousel tab. Every card has three parts:

  • Image: upload a PNG or JPEG.
  • Caption: up to 80 characters. The product name and price is usually enough.
  • Button: one link button per card, pointing to that product.

Use + Add Card to add more cards, up to five in total. The phone preview beside the form shows the carousel the way your customer will see it.

4. Save and activate

Click Save & Activate. To test it, comment your keyword on the post from a second Instagram account and check that the carousel arrives.

  • Lead with your best seller. The first card is the one everyone sees, so it gets the most attention.
  • One product per card. A card that tries to show a bundle is harder to read and harder to click.
  • Keep captions short. Eighty characters is the limit, and shorter reads better on a small card.
  • Say which word to comment. Put the keyword in your post caption or on the image, so people know what to type.
