How comment to DM works
You have seen it: "Comment GUIDE and I'll send it to you." Here is what happens behind that sentence.
The chain
- Someone comments your keyword under a post.
- Postfjord checks the keyword and posts a short public reply: "Sent! Check your DMs, it may be under message requests."
- At the same time it sends the person a private message.
- They tap a button or link and get what you promised.
The public reply is optional, but other followers see the promise is real, and more of them comment.

Two Meta rules
One private reply per comment. That is why the first DM asks a small question with a button, "Want the guide?" A tap opens a real conversation, and from then on you can keep writing to that person. If you skip the question and send the link straight away, you cannot follow up until they write to you.
A 24 hour window. After a person writes to you or taps your button, you have 24 hours to message them. Automation never sends outside that window. Lesson 5 uses it for a follow-up.
Message requests
The first message from a business almost always lands in message requests, a folder most people never open. Say so in your public reply. The replies Postfjord starts you with already do.
Do it
- Find an account near you that says "comment a word and I'll send it".
- Write down the keyword, what the person gets and what the post looks like.
- Write the one thing you could send your own followers the same way.

Someone tapped your button yesterday at 3 pm. Can an automation still message them today at 5 pm?
