13 Best Podcast Marketing Tools in 2026 (Compared & Ranked)

Most lists of podcast marketing tools are hosting lists wearing a different hat. They open with five podcast hosts, add a microphone, and never get to the part where somebody actually finds your show.

This one excludes tools used only for production. Every tool below earns its place through work that happens after you hit publish: making clips, collecting email addresses, getting the episode into search results, working out who your listeners are, or running the promotion work for you. A few also record or edit, and they qualify because they create the assets used to market the episode.

Short answer: three tools cover most shows. Something that turns an episode into clips, something that collects email addresses, and a website that publishes your transcripts. Everything else on this list solves a narrower problem, and the AI agents at the top solve the problem of nobody having time to do any of it. We build Castos, so three of the 13 are ours and they are marked as such.

Key takeaways

• Podcast marketing tools are not production tools. Microphones and editing software make the episode. Marketing tools get it in front of people, and mixing the two is why most of these lists are useless.
• The cheapest wins are free. Kit is free to 10,000 subscribers, beehiiv to 2,500, OpusClip and Headliner both have free tiers for clips.
• Transcripts are the highest-leverage marketing asset a podcast has, because audio contains no text a search engine can read.
• AI has moved past show notes. Agent tools now plan and run SEO, paid and lead generation work, with a human approving the plan before it executes.
• Three tools is a stack. Nine is a hobby. Add one only when you can name the job it does that nothing you already pay for can.

What counts as a podcast marketing tool

A marketing tool changes how many people hear the episode. That is the whole test, and it rules out most of what usually appears on these lists.

Not on this list, on purpose: microphones, audio interfaces and recording gear used only for production. Those change the quality of the episode, not its reach. Tools that record or edit but also produce marketing assets, like Descript and Riverside, pass the test on the marketing half of what they do. If that is what you came for, we keep separate guides to podcast equipment and podcast editing services.

Also not here: your podcast host. Hosting is the plumbing every show needs, marketing or not, and we compare the options in podcast hosting platforms.

What is left splits into five jobs: AI agents and assistants, clips and audiograms, email, search visibility, and research. Pick one tool per job you actually have.

AI marketing tools for podcasters

This category did not exist in a useful form two years ago, and it is where most of the movement is now. The pattern has shifted from AI that writes show notes to AI that runs campaigns.

1. Castos AI Assistant

$10/month add-on to any Castos plan; plans start at $19/month. We make this one.

It reads the episode and drafts the things you would otherwise write at 11pm: titles, show notes, summaries, chapter markers and social copy. The podcast AI assistant works from your actual audio rather than a prompt, so the output references what was said in the episode.

The honest limitation. It writes the assets; it does not post them. The episode itself is already handled, since Castos distributes it to every directory the moment you publish. What is left is the social side: pair the assistant with a clips or email tool from this list to get its output in front of people.

2. Descript

Free tier, Hobbyist from $16/month billed annually. Descript turns your audio into a text document and edits the audio when you edit the text. Delete a sentence, the sentence disappears from the recording.

For marketing, the useful part is how fast you can pull a clip. Find the good bit in the transcript, highlight it, export.

3. Delegento

Free trial, then $99/month for the Starter plan, which includes 10,000 credits. Larger credit packages go up from there.

Delegento is for podcasters using the show to grow a business or a personal brand, where the marketing work extends well past publishing clips. Its AI agent, Delo, plans and executes SEO, paid acquisition, lead generation and content work. You set the goal, review the plan, and approve the job before it runs.

The published scope covers paid campaign reviews and spend analysis, SEO traffic analysis and content briefs, AI visibility work on how a brand appears in AI answers, prospect research and outreach preparation, ad angles and copy variants, and founder and company branding posts. It connects to the tools you already use rather than asking you to work in another dashboard.

Where it fits. A podcast that exists to sell something. If the show is the business, this is a marketing hire. If the show is the hobby, it is far more tool than you need.

Worth being clear about: there is no podcast-specific feature here, and that is the point. It handles the marketing around the show, not the show itself.

4. Castmagic

$19/month on the Hobby plan billed annually, no free tier. Upload an episode and it produces show notes, timestamps, blog posts, social copy and newsletter drafts in one pass.

It overlaps heavily with the Castos AI assistant if you host with us. It earns its place for shows that want the full content set from every episode, including the blog post and the newsletter.

5. OpusClip

Free plan, Starter at $15/month. It watches a long recording, finds the moments most likely to work as short video, and cuts them with captions.

The honest limitation. It picks moments by pattern, not by judgement, so about one clip in three is worth posting. That is still a much better rate than doing it by hand at midnight.

Clip and audiogram tools

6. Headliner

Free forever with one unwatermarked audiogram a month, Basic at $7.99/month billed annually. Headliner turns audio into a shareable video with a waveform and captions, which is how audio-only shows post to platforms built for video.

The free tier is genuinely usable if you post one clip a month and do not mind watermarks on the rest.

7. Riverside

Free tier, Pro at $24/month billed annually. Riverside records remote interviews in high quality, and its Magic Clips feature generates social clips from what you just recorded.

Where it fits. Video podcasts that would rather generate clips at the recording stage than run the file through another tool afterwards.

Email and audience tools

Social platforms rent you an audience. Email is the only channel you own, and it is the one podcasters skip most often.

8. Kit

Free up to 10,000 subscribers, Creator at $33/month billed annually. Formerly ConvertKit, Kit is built for creators rather than for ecommerce, which shows in how simple the automations are.

The free tier being that generous makes this close to a default. A show with 800 email subscribers has a more reliable launch mechanism than a show with 8,000 social followers.

9. beehiiv

Free to 2,500 subscribers, Scale at $43/month billed annually. More opinionated than Kit, with growth and referral features built in and a website attached to the newsletter.

Where it fits. Shows where the newsletter is a product in its own right rather than an episode announcement.

Website and search visibility tools

10. Castos podcast website

Included with Castos, from $19/month. Ours. Every show gets a podcast website with an episode page per episode, so the show has somewhere to rank that is not a directory listing.

The reason this is a marketing tool rather than a nicety: a directory page belongs to Apple or Spotify, and an episode page belongs to you.

11. Podpage

14-day trial, Basic at $12/month billed annually. Builds a podcast site from your RSS feed, which suits shows whose host does not include one.

12. Castos transcriptions

Included with Castos, from $19/month. Ours. Episode transcripts are the single highest-leverage marketing asset a podcast has, and almost nobody treats them that way.

The reason is mechanical. An audio file contains no text. A search engine reading your episode page sees a title, a paragraph of description and a player. Publish the transcript and the same page suddenly contains every question your guest answered, in their words. That is what makes a podcast findable through search, and it is covered in more depth in podcast SEO.

Research and discovery

13. Podchaser

Free, with paid Pro tiers on request. A database of shows, episodes, credits and reviews. Podcasters use it for two things: finding shows to pitch yourself to as a guest, and finding guests worth having on.

Guest swapping remains the most reliable growth channel in podcasting, and this is the tool that makes it systematic rather than random.

Measuring whether any of it works

None of the above tells you whether it worked. That is a separate category, and we wrote it up separately in the best podcast analytics tools.

The short version: your host reports the total across every app, Apple and Spotify report what happened inside their own apps, and you need both to see whether a campaign moved anything. Watch downloads in the seven days after a push, not the same day, because podcast listening lags publishing.

How to build your stack

A new show. Transcripts, one clip tool, and an email list on a free plan. That is it. Anything else is procrastination with a credit card.

A growing show. Add a proper podcast website with episode pages, and start doing guest research rather than waiting for guests to appear. This is also the point where promoting the podcast becomes a repeatable weekly routine rather than a burst after each launch.

A show that is selling something. Add the AI agent layer and connect the podcast to the funnel it is meant to feed. At this stage the marketing work is bigger than the show, and it needs somebody or something running it full time.

The rule for all three: never add a tool you cannot name a job for. The list above is 13 tools and no podcast needs more than four of them.

FAQs about podcast marketing tools

What are podcast marketing tools?

Podcast marketing tools are the software you use to get an episode in front of people after it is published: clip and audiogram makers, email platforms, podcast websites, transcription for search, listener research, and AI agents that run the promotion work. Recording gear and editing software are production tools, not marketing tools.

What is the best free podcast marketing tool?

Kit, with a newsletter plan free up to 10,000 subscribers. Headliner gives you one unwatermarked audiogram a month free, OpusClip has a free plan for clips, and beehiiv is free to 2,500 subscribers.

How do I promote a podcast without a budget?

Publish a transcript with every episode, cut one clip with a free tool, and start an email list on a free plan. Those three cost nothing and cover search, social and direct audience.

Do podcast transcripts help SEO?

Yes. Audio contains no text a search engine can read, so the transcript is what makes an episode indexable. Publishing transcripts turns every episode into a page that can rank for the questions your guests answered.

Can AI do podcast marketing for you?

Partly. AI handles the repetitive work reliably: show notes, titles, clips, transcripts, social copy. Agent tools like Delegento go further and plan and run SEO, paid and lead generation work, with you approving the plan before anything executes.

How many marketing tools does a podcast need?

Three for most shows: something that makes clips, something that collects email addresses, and a website that publishes transcripts. Add more only when you can name the job the new tool does that your current stack cannot.

Where to start

Pick the job you are worst at. If nobody can find the show, start with transcripts. If nobody remembers it between episodes, start with email. If nobody sees it on social, start with clips.

If you host with Castos, transcripts and the podcast website are already in your plan and the AI assistant is a $10 add-on, so the first job is switching them on rather than buying anything.
