How comment to DM works
Three steps in the BuzzWire app, no code.
- Step 1
Pick your posts and keyword
Choose every post and Reel, or only the ones you pick. Add one or more keywords, like PLAN or GUIDE.
- Step 2
Write the DM
Write it once with a few variations and {{username}}, then add your link. Preview it on an iPhone before it goes live.
- Step 3
Turn it on
Add an optional public reply, switch it on, and every matching comment gets your DM, paced within Instagram’s limits.
Public replies rotate between your variations, or go on every Nth comment.

Tips for better results
What should the DM say?
Thank them by name, give the link in the first message and keep it short. One link per DM reads best. Message variations keep each DM sounding like you.
Which keyword works best?
One short, easy word that matches what you’re giving away, written in capitals in your caption and said out loud in the Reel: PLAN, RECIPE, GUIDE. Add common misspellings as extra keywords.
What happens to other comments?
Only comments with your keyword trigger a DM. Every other comment stays in your thread for you to answer, and the public reply can thank people who asked for the link.
