You've seen the caption a hundred times: "Comment LINK and I'll send it to you." It's the oldest trick on Instagram and it still works, because it asks for the smallest possible action and rewards it privately. thx.so now does the sending for you.
Why comments beat bio links
Instagram shows a post to more people when it gets comments early. A comment is also a much smaller ask than "tap my profile, find the link, tap again." When the reward for commenting is the thing the viewer wanted, delivered by DM, people comment. The post travels further and the fan lands exactly where you wanted them.
The DM does something else too. Once a fan has messaged you, a conversation window is open. That's worth more than any single click.
Four triggers, one rule each
An automation on thx.so is a rule with a trigger and one or two actions.
- Comment with keyword. Someone comments a word you chose, on all your posts or only the ones you list.
- Any comment. Every comment on chosen posts, useful for a launch post where the whole point is the link.
- DM with keyword. A fan messages you a word, like "GUIDE" or "PRICE".
- Story mention. Someone tags you in their story.
The first enabled rule that matches wins, and the rest are skipped for that message, so rules stay predictable when you have several.
Reply and DM
A comment trigger can post a short public reply under the comment, so other viewers see that it worked, and send the private DM with the link. DM and story triggers just send the DM.
Fixed text is right for a link drop. Write it once with tokens like {name}, {link} and {message} and it reads like you typed it. When comments carry real questions, switch the rule to AI. It writes one reply from your instructions, your bio and what the fan actually said, in your voice, and still includes the link. Preview any rule against a sample comment before you save it.
Cards and quick replies
A DM doesn't have to be a bare URL. Attach a card with an image, a title and up to three buttons, and add quick replies so the fan can tap "Send it" or "Tell me more" instead of typing. Comment triggers send a single private reply, so cards apply to DM and story rules.
Setup in five minutes
- Switch your Instagram account to a professional account if it isn't already. It's a free setting inside the Instagram app, and personal accounts can't be automated by any tool.
- In thx.so, go to Integrations, Connections, and connect Instagram.
- Write one rule. Start with a comment keyword and a fixed-text DM.
- Post, tell your audience the keyword, and watch the activity log. Every comment, what matched, and what was sent shows up there.
What it costs
AutoDM is part of thx.so on every plan, and fixed-text replies are unlimited. AI-written replies come with a monthly allowance that grows with your plan, so a post that goes further than expected can't surprise you.
