A voice note campaign is a DM campaign that sends a recording of your voice to a chosen group of Instagram contacts. Each contact receives it as an audio message in their Instagram DMs.
A voice note campaign is a DM campaign whose message is a recording of your voice. In Inrō you record or upload the audio once, and each contact in your audience gets it as an audio message in their Instagram DMs, not as a link to a file.
Build a DM campaign in Inrō, choose the audience, then add the "Send audio message" step. The step opens a window with two choices:
The same step works in a scenario on the Scenarios page. That lets you answer a story reply with your voice, through a story reply trigger, or follow up a comment with comment to DM automation. Developers can send audio too, with message type audio in the Inrō public API.
The Meta for Developers documentation on the Instagram Messaging API lists four audio formats for DMs: aac, m4a, wav and mp4, up to 25 MB (Meta, checked 1 October 2026).
Inrō accepts MP3, M4A, AAC and WebM uploads, and browser recordings. Inrō converts other formats for you, so an MP3 from your phone arrives in a format Instagram accepts. Inrō refuses audio files above 25 MB.
Each voice note goes out as a normal DM, one per contact. A large audience is sent in batches, as the batch task entry explains. On the step, you see how many were Sent and how many were Seen. Seen comes from the DM read receipt Instagram sends when the contact opens the message.
The same people as any other message in a DM campaign. The Instagram Messaging API documentation gives a business 24 hours to answer a message from an Instagram user (Meta, checked 1 October 2026). So a voice note reaches a contact only while their 24-hour messaging window is open. How many DMs Meta accepts in a given time is a separate matter, the Instagram rate limit.
Inrō's page for artists and musicians suggests sending superfans a voice note or an early preview of your next release. More flow building blocks are in the Instagram automation glossary.
