Comment-to-DM

Comment-to-DM is the automation most people come for. Someone comments a word on your post; they get a message from you with whatever you promised.

The five fields

It is a preset, not a blank builder:

1. The post it watches.
2. The keyword that triggers it.
3. The message that gets sent.
4. The link, if the message carries one.
5. The public reply, if you also want to answer in the comments.

That is the whole thing. No schema, no flow chart, no branch.

Choosing a keyword

Pick something people will type exactly and would not type accidentally. One word, no punctuation, not a word that appears in ordinary praise. "GUIDE" works; "yes" does not, because half your comments will contain it.

Matching is on the comment containing the keyword, so "guide please" still fires.

Write the message like a person

The message is sent as you, into a private inbox, to someone who just raised their hand. Say what they asked for, give them the link, and stop. The messages that get reported are the ones that open with a sales pitch nobody asked for.

If you promise something in the post ("comment GUIDE and I'll send it"), the message must contain that thing. That is both the decent thing and the rule the platforms enforce.

Also reply publicly

Answering in the comments as well is worth switching on. It shows other readers the automation worked, and it means the person who commented is not left wondering whether anything happened.

On TrendSuite Lite

Lite has this and only this, at Auto reply, stated in one sentence: when someone comments a word on your post, we send them a message. Same engine, same safety rules, no builder.

What decides whether it actually sends

Platform messaging rules, not us. A DM can only be sent inside the window the platform allows and with the disclosure it requires. See staying inside platform rules: it is the page that explains most "why didn't it fire" questions.
