Start from a real pattern
Every one of these is a real automation you can build in under a minute — pick the trigger kind, write your message, publish.
Templates
"Link" comment → DM
Someone comments "link" (or any keyword you pick) on a specific post → they get a DM with the link, instantly, plus a public reply so it looks natural in the thread.
Giveaway entry
Any comment on your giveaway post triggers a confirmation DM — capture every entrant automatically, no manual screenshotting required.
FAQ auto-reply
DM keyword matching ("price", "shipping", "hours") replies instantly with your answer — build one per common question.
Story mention shoutback
Anyone who mentions your account in their story gets an automatic thank-you DM — great for reposts and UGC campaigns.
