Instagram Direct, also known as Instagram DMs, is the private messaging feature built into Instagram. It lets you send texts, photos, videos, and other media to people one-on-one or in groups. Meta launched this feature on December 12, 2013, to compete with messaging apps like Snapchat.

Instagram Direct by the Numbers

Instagram Direct has grown into a major communication platform. Here are the key statistics:

  • 375 million monthly active users
  • 400+ million daily business messages
  • 80% of Instagram users follow at least one business
  • 75% of consumers prefer engaging brands via private messaging

How Instagram Direct Has Changed Over Time

2013 Launch

When Instagram Direct first launched, you could only send photos. You needed to include an image to start any conversation. Group chats were limited to 15 people.

2015 Updates

Instagram added text-only messages, so you no longer needed to send a photo first. They also increased the maximum group size.

2020 Major Changes

This was a big year for Instagram Direct. Meta enabled cross-platform integration with Facebook Messenger. They added Vanish Mode for messages that disappear after viewing. New features included message reactions, threading, and animated effects.

2023 Broadcast Channels

Instagram launched Broadcast Channels, allowing creators to send one-to-many messages to their followers.

Core Features of Instagram Direct

Disappearing Messages

Vanish Mode automatically deletes messages after you view them. View Once works for individual photos and videos you want to disappear after being seen.

Rich Media Sharing

You can send photos, videos, voice notes, GIFs, stickers, and shared posts or Reels through DMs.

Interactive Elements

DMs include emoji reactions, threaded replies, typing indicators, and read receipts so you know when someone has seen your message.

Group Chats

Regular group chats support up to 32 participants. In some cases, groups can include up to 250 members.

Story Integration

When someone replies to your Story, the reply goes directly to your DM thread with that person.

Broadcast Channels

Creators can use Broadcast Channels to send updates to all their followers at once. Only the creator can send messages, but followers can react.

How to Send a Direct Message

Sending a DM on Instagram is simple:

  1. Tap the paper airplane icon in the top right corner of your home screen
  2. Select New Message
  3. Choose the username or usernames you want to message
  4. Type your message and hit send

Messages from people you do not follow appear in a separate Message Requests folder. You can review and accept or decline these requests.

Security and Privacy

There are some important things to know about DM privacy:

  • Regular DMs do not have end-to-end encryption by default as of 2025
  • Meta is testing an optional encrypted chat mode
  • Instagram notifies you if someone screenshots disappearing content
  • You can message Facebook Messenger users from Instagram, but WhatsApp remains separate
