Story replies and story mentions

Send an automatic DM when someone replies to your Instagram story or @-mentions you in theirs: what fires, what they get, and the limits.

Updated

Not every conversation starts under a post. Someone answers your story with “price?”, or posts their own story and tags you in it. Dartzo has two triggers for those moments: Reply to my story and Mention in a story. Both send a DM to the person who reached out.

Where to find them
The trigger cards live in the studio’s Advanced mode (the switch at the top right). Under *Account-wide* you’ll see Reply to my story (“Someone replies to your story → DM back.”) and Mention in a story (“Someone @-mentions you in their story → DM.”). Simple mode keeps the trigger on *comment*. New to the studio? Start with Build your first automation.

How they differ

Reply to my storyMention in a story
What fires itA fan sends a reply to one of your stories.A fan @-mentions your account in their own story.
KeywordsOptional. You can match words in their reply, or reply to every story reply.None. There’s no text on a mention, so it fires on every one.
Which storyAny story. You can’t pick a single story yet.Any story that mentions you.
Exclude wordsYes (Advanced).No — nothing to exclude from.
Public reply under itNo. There is no comment to reply under.No.

Both are account-wide. A comment automation belongs to one post; these belong to your whole account, so they have no post to pick. If you switch an automation from a comment trigger to one of these, the studio warns you that the post you chose will be detached. And once an automation is saved, its trigger can’t be changed — create a new one instead.

Reply to my story

The first step in the studio reads Story — Any story, then Keywords. You have two choices there:

  • Reply to every story reply — switch this on and no keyword is needed. Anyone who replies to any of your stories gets the DM.
  • Keywords — add words like PRICE or MENU. Dartzo reads the text of the reply and fires only when it matches. Matching ignores capital letters. How the words are compared is covered in Keyword match modes.

A reply that doesn’t match any rule just doesn’t trigger an automation. It still lands in your Instagram inbox like any other message.

“Every story reply” means every one
A fan who sends a heart-eyes emoji and a fan who asks a real question both get the same DM. If you run several stories at once and want different answers, use keywords — and see Which automation wins for what happens when more than one rule matches.

Mention in a story

When someone tags you in their story, there is no sentence for Dartzo to read, so the keyword section is replaced by a single line: *Fires on every story mention (no keyword).* Every mention gets the DM.

This is a good one for a thank-you plus a small reward, because the person has just shown your account to their own followers. Keep it warm and short; you are talking to someone who already likes you.

What the fan receives

You write the DM exactly as you would for a comment automation: the message, an optional link, and {{first_name}} / {{link}} placeholders. One difference worth knowing: because the fan has just messaged you, the conversation is already open, so the first DM can carry your buttons straight away. On a comment trigger the first message is a private reply, and it can only carry the quick-reply opt-in, not a link button. See Buttons and links.

The limits that apply

LimitWhat it isWhose rule
Reply window24 hours from the fan’s message. Dartzo’s own deadline is 18 hours, so a send never lands at the edge of the window.Instagram’s 24-hour messaging window, minus Dartzo’s 6-hour margin
One DM per personA fan who replies to your story five times in a day gets one DM from that automation, not five.Dartzo’s guard (24-hour cooldown per automation and person)
Sending speedUp to 100 messages per second for these triggers. They don’t use the hourly allowance that comment replies use.Instagram’s messaging throughput

If a DM can’t go out the moment it’s matched, it waits in the queue and is sent while the window is still open. If the window closes first, it’s marked as expired in your delivery log instead of vanishing. Limits and windows has every number, and How delivery works explains the queue.

Setting one up

  1. Open Advanced mode
    In the Automation Studio, flip the switch at the top right from Simple to Advanced.
  2. Pick the trigger
    Under *Account-wide*, choose Reply to my story or Mention in a story.
  3. Set the words
    For story replies, add keywords or turn on Reply to every story reply. Mentions need nothing here.
  4. Write the DM
    Write the message, add your link, and add buttons if you want them.
  5. Go live
    Press Go live. Nothing is live until you do.
Two rules on the same trigger
Story replies are one pool for your whole account. If you build two Reply to my story rules with the same keyword and match type, Dartzo refuses the second and links you to the first, because only one could ever fire. Give one a different keyword or turn on Pin priority (Advanced). Details in Which automation wins.
Can I run an automation on just one specific story?
Not yet. Story automations apply to any story on your account: the studio shows “Any story” for replies and “Any story that mentions you” for mentions. If you need different answers for different stories, use different keywords and tell people which word to reply with.
How long do I have to send the DM after someone replies to my story?
Instagram allows a reply within 24 hours of their message. Dartzo aims to send straight away and treats 18 hours as its own deadline, leaving a 6-hour safety margin. If a send can’t happen inside that time it is marked as expired in your delivery log, not left as a mystery.
Does a story mention need a keyword?
No, and it can’t have one. A mention carries no text for Dartzo to read, so the automation fires on every story that mentions you.
Will someone get the same DM twice if they keep replying?
No. Dartzo sends one DM per person per automation in any 24-hour period. Their extra replies still show up in your inbox for you to answer yourself.
