Public Instagram Comment Reply vs Private DM
A comment is public. A DM is not. Tools that “auto reply to comments” often blur that, which is why people search for public reply versus private DM as if they were two products. They are two API actions on the same comment.
Use a public reply when
- The answer helps the next person who reads the thread (shipping times, “yes this fits UK sockets”).
- You want social proof that you answer.
- You need to tell them the DM is in Message Requests.
Use a private DM when
- The payload is a URL, discount, or personal next step.
- You do not want every lurker clicking the same affiliate link in the comments.
- You need a button, a card, or a follow-gate before the link.
Doing both
CommentLink’s comment automations can send a short public reply and a DM together. Native Custom Keywords are built around the DM side. If you only need the public “thanks, sent you a message,” a human or a workspace that supports public replies is the difference.
Tone
Public copy is part of the brand. Keep it a sentence. Put the long pitch in the DM. That split is also kinder to people who never wanted a sales thread on a photo of their lunch.

Choose a public comment reply, a private DM, or both — from the same automation.

What CommentLink Does Not Do (No Cold DMs)
CommentLink does not send Instagram DMs to people who never engaged. No password logins, no scraped target lists, no comment→WhatsApp. Official Meta OAuth only.
Story Mention Thank-You DMs
When someone mentions your brand in their Instagram Story, a STORY_MENTION automation can send a thank-you DM and an optional link. It is not a new-follower webhook.
