Comment-to-DM became popular on Instagram reels, but people often ask whether the same thing works on Facebook or Threads.
Facebook Pages
Facebook Pages also allow replying privately to comments through Meta's API, so some tools offer comment-to-Messenger automation for Facebook posts. It is a separate setup from Instagram, with Messenger instead of Instagram DMs.
Threads
Threads has its own API, focused on publishing and reading posts and replies. Comment-to-DM style automation on Threads is not common, and messaging on Threads works differently from Instagram. Check a tool's current features before relying on it.
What DM Flow supports
DM Flow is built for Instagram only: comment-to-DM, public replies, follow-gate and lead lists for Instagram professional accounts. It does not automate Facebook Pages, Messenger or Threads.
If you need Facebook and Instagram from one tool, a multi-channel platform such as ManyChat may suit you better. See our honest DM Flow vs ManyChat comparison.
Where to focus
For most Indian sellers and creators, Instagram reels bring the most comments asking for links. Start there, and add other channels only when they bring real demand.
