Using the Composer
This page walks you through every part of the Composer so you can send tracks with confidence.
The Composer is where you prepare and send tracks to another user’s inbox. It allows you to choose your sending profile, add tracks, include a message, and select whether you’re sending a Demo or Promo.
Choose Your Sending Profile
At the top of the Composer, you’ll see the From menu. This allows you to select which of your profiles or workspaces you want to send from — ideal if you manage multiple artists, labels, or brands.
Selecting the correct sending identity ensures recipients know exactly who the submission is coming from.
Choose the Recipient
Under To, select the inbox you want to send your tracks to.
You can search for any public inbox.
Verified inboxes are marked with a blue tick.
You can also click View History to see your previous submissions or interactions with that recipient.
This helps you keep track of ongoing relationships and past promos.
Add a Message
You can include a short message with your submission. This is optional but recommended — especially for promos, label submissions, or follow-ups.
Examples include:
Context about the track
Release date or promo details
Supporting notes or personal messages
Keep it brief and clear.
Select Demo or Promo Mode
At the top-right of the Tracks section, you can choose whether you're sending:
Demos
Promos
This helps recipients sort and prioritise incoming submissions.
Add Your Tracks
You can send up to 5 tracks per submission.
To add a track:
Click + Add Track
Select a track from your Library
Assign the genre for each track
Genres help the recipient filter their inbox and understand the context of your submission.
Each track appears as a card showing:
Title
Artwork (if available)
Genre dropdown
Remove option
You can add or remove tracks until you're happy with the selection.
Review Submission Details & Send
Before sending, double-check:
Sending profile
Recipient
Message
Track list and genres
Submission type (Demo or Promo)
This ensures your submission is accurate and professional. Once ready, click send. Your submission will be delivered to their inbox instantly. You can revisit past submissions via View History.

The Composer is your central tool for creating clean, professional submissions on Trackstack. Whether you’re sending demos to labels or promos to DJs, it helps you:
