Where Instagram story mentions go

When someone tags your account in their Story, Instagram sends it to your direct messages as a story mention. From there you can reply in the chat or add their Story to your own. Instagram doesn't answer these for you: there is no built-in setting that thanks people for mentions.

Short answer Story mentions arrive as DMs. To answer them automatically you need a tool on Instagram's official messaging API, replying within 24 hours of the mention.

The rules any tool works within

  • Professional account. Messaging automation works for Business and Creator accounts.
  • 24 hours. Apps can reply within 24 hours of the person's message, which for a mention means within a day of it arriving.
  • A reply, not a reshare. Tools answer in the chat. Adding their Story to yours is still done by you in the app.
  • One thank-you, not a campaign. A mention is a gift; a sales sequence in return feels like the opposite.

Thank-you replies to adapt

  • “You just made my day, thank you for sharing this!”
  • “Thank you so much for the shout-out! Hope you enjoy [it].”
  • “Love seeing this. Thanks for taking us along!”
  • “This means a lot, thank you! Let me know how you get on with [it].”
  • “Thanks for the mention! I'm adding this to my Story.” (only if you will)
The template problem Send the same line to everyone and the regulars notice by the third mention. The point of a thank-you is that it's for them.

Thank every mention in your own voice

Disclosure: PersonaXpand is our product. Story mentions arrive with your other Instagram messages, and PersonaXpand drafts a reply to each in your own voice through Instagram's official API, so the hundredth thank-you doesn't read like the first. Approve each with a tap, or let routine ones go out on their own.

If the person also asks something, such as a price or where to buy, it doesn't guess: that message is left for you. Each person gets at most a handful of automatic messages a day, so nobody is bombarded. More in Instagram DM auto-reply.

Frequently asked questions

Can Instagram auto-reply to story mentions?

Not by itself. Story mentions arrive in your DMs, and answering them automatically needs a tool on Instagram's official messaging API, such as PersonaXpand.

Where do I see Instagram story mentions?

In your direct messages. Each mention arrives as a message showing their Story, where you can reply or add it to your own Story.

How long do I have to reply to a story mention?

You can reply in the app any time. Apps answering through Instagram's API have to reply within 24 hours of the mention.

Can a tool reshare story mentions to my Story automatically?

No. Instagram's API lets apps reply in the chat, but adding someone's Story to yours is done by you in the app.

What should I say when someone mentions me?

A short, specific thank-you. Mention what they shared if you can, and don't follow it with a sales pitch.
