What you get

Your back catalog becomes your best marketing channel

Launch a course, sell event tickets, or thank a sponsor in front of every listener, not just the ones who caught this week's episode.

  1. One recording does all the work

    Drop in a short promo, sponsor read, or announcement. Save it to your library and bring it back whenever you need it.

  2. Every listener hears it, on every episode

    Your clip plays before or after every episode of your show, new and old. Your original files are never touched.

  3. Turn your audience into customers

    Reach the whole audience with your offer, including people bingeing your back catalog for the first time. More ears on the offer means more people taking you up on it.

  4. It ends on time, on its own

    Set the start and end dates and walk away. On Growth and up, schedule campaigns ahead of time so your next launch is ready before you are.

Everything you need to run a campaign

Campaigns is free for every Castos customer. Growth and up adds scheduling and more campaigns.

  • Pre-roll and post-roll audio

    Add a clip before your episode starts, after it ends, or both.

    Every plan

  • Your whole show, old and new

    A campaign runs across every audio episode of the show you choose, including your back catalog.

    Every plan

  • Originals never change

    Castos plays your clip alongside the episode. The files you uploaded stay exactly as they are.

    Every plan

  • A clip library

    Save promos and sponsor reads once, then reuse them in future campaigns in a couple of clicks.

    Every plan

  • Start and end dates

    Campaigns stop on their end date by themselves, so an expired offer never lingers in your feed.

    Every plan

  • Scheduling and more campaigns

    Line up campaigns in advance and run more than one. Essentials includes one campaign at a time.

Campaigns questions

What are Castos Campaigns?
Campaigns adds your own pre-roll and post-roll audio, like promos, sponsor reads, or announcements, to every audio episode of a show for the dates you choose.
Does a campaign change my original episode files?
No. Your uploaded files are never modified. Castos plays your clip before or after the episode, and when the campaign ends, listeners hear the episode exactly as you published it.
How much do Campaigns cost?
Nothing. Campaigns is free for every Castos customer. Essentials includes one campaign at a time; Growth and up add scheduling and more campaigns.
Which episodes does a campaign run on?
Every audio episode of the show you pick, including your back catalog, so new listeners discovering old episodes hear it too.
What happens when a campaign ends?
It switches off by itself on the end date. You can also end it early whenever you like.
What's the difference between Campaigns and Castos Ads?
Campaigns plays audio you provide. Castos Ads fills ad spots automatically and pays you for them. You can use both.
