Listen to Substack newsletters as audio
Subscribe your private InboxToAudio address to a newsletter, or forward the issues you already get, and every one comes back narrated.
Free and paid publications both work — it reads the email, not the platform.

Two ways to listen to a Substack
You can either send issues over one at a time, or point the newsletter at your listening address so every future issue arrives as audio without you doing anything.
Forward an issue
Hit forward on the email you already received and send it to your private listening address. Best when you only want audio for the occasional long piece.
Subscribe your listening address
Enter your InboxToAudio address on the newsletter’s signup form. Every new issue is narrated automatically and appears in your queue, with no forwarding step.
Most people do both — subscribe the two or three newsletters they always want narrated, and forward everything else as it comes up.
Subscribing your listening address, step by step
- 1
Copy your address
Find it in your listening settings. It looks like alpha.beta.12345@inbox.inboxtoaudio.app and it is unique to your account.
- 2
Paste it into the newsletter signup
Use the normal “subscribe” box on the publication’s page, exactly as you would with any other email address.
- 3
Confirm the subscription
Many publications send a one-time confirmation email. It arrives at your listening address, so open your listening inbox, find the message, and click the confirm link there — otherwise the subscription never starts.
- 4
New issues arrive as audio
Each issue is cleaned, narrated in your chosen voice, and waiting in your queue with chapters and a transcript.
Paid newsletters work too
A paid subscriber email is just an email. When a paid issue reaches your inbox you can forward it and listen to it, the same as a free one — you are listening to content you already pay for, on your own account.
Audio stays private to you. Nothing is published, there is no public feed, and share links exist only for the individual episodes you choose to share.
If you subscribe your listening address directly to a paid publication, use the address the payment is attached to, or keep the paid subscription on your normal inbox and forward issues across.
Works with the other newsletter platforms too
- Substack — free and paid publications
- Beehiiv, Ghost, and Mailchimp newsletters
- ConvertKit, Buttondown, and plain company mailing lists
- Industry digests and daily briefings, however they are sent
The pipeline reads email, not a platform API, so anything that reaches your inbox as text can be narrated regardless of what sent it.
What listening to a newsletter is actually like
- Sponsor blocks, unsubscribe footers, and “view in browser” lines are stripped before narration
- Long issues are split into chapters so you can skip a section you do not care about
- The transcript is there when you want to grab a quote or a link
- Playback speed is adjustable, with a default you set once
- Your position is saved, so a half-finished issue picks up where you stopped
Frequently asked questions
- Two ways. Forward an issue to your private InboxToAudio address to narrate it once, or enter that address on the publication’s signup form so every future issue is narrated automatically and lands in your listening queue.
Stop letting good writing pile up unread.
