Podcast Database and Contact List for Advertisers

Ten companies capture about 60% of US podcast ad revenue. The other 40% goes to a long tail of smaller players¹. Most of those shows don't have a sales team. The host sells the ads, and the only way to buy is to email them. That's why advertisers look for a podcast database with contact emails.

This page explains what a podcast database for advertisers should include, which fields matter, how a database differs from an ad marketplace, what each option costs, how to judge coverage, and a 30-minute workflow from search to sent email.

Key takeaways

• A podcast database for advertisers lists shows with their category, country, language and a contact email for the host or booking contact, so brands can buy sponsorships directly.
• Self-serve podcast ad platforms start at about $200 to $250 per campaign, but they sell placed spots and keep buyer contact inside the platform or skip it.
• Ten companies capture about 60% of US podcast ad revenue, and the remaining 40% sits with a long tail of smaller shows and sellers, per Owl & Co.
• Only 470,213 of 4,758,122 feeds in Podcast Index posted an episode in the last 90 days, so a useful database must help you avoid dead shows.
• US CAN-SPAM rules cover business-to-business email and require a truthful sender, an accurate subject line, a postal address and an opt-out honored within 10 business days.

What a podcast database should include for advertisers

Most podcast directories were built for listeners or for guests pitching interviews. An advertiser needs something else. You need to find shows your buyers hear, then reach the person who sells the ads.

So a podcast database for advertisers has two jobs.

• Find. Filter thousands of shows down to the few dozen that fit your buyer, by topic, country and language.
• Reach. Give you a working email for the host or booking contact, so you can ask for rates and dates.

A database that only does the first job is a search engine. A spreadsheet of emails with no filters is a mess. You need both in one place, plus a way to save a shortlist and send the outreach.

Why direct contact matters so much. Agencies and hosting platforms commonly look for about 5,000 US downloads per new episode in the first month before they'll sell a show². Most podcasts sit below that line, so they sell their own sponsorships². If you want those shows, and their lower prices, you deal with the host.

Who uses a podcast database

• DTC brands testing host reads on 10 to 20 niche shows before they scale.
• B2B and SaaS teams looking for small shows that reach one job title, such as founders, recruiters or IT leads.
• Agencies building podcast plans for several clients at once, with one saved list per client.
• Publicists who book guest spots and sometimes paid sponsorships for the same clients.

The job is the same in each case. Find the right shows, get the right person, and ask a clear question about price and dates. The rest of this page walks through how to do that well.

The fields that matter

When you compare podcast databases, check for these fields. Each one saves you a step.

Why activity matters most

Podcast Index tracks 4,758,122 podcast feeds. Only 470,213 posted an episode in the last 90 days, and 346,652 in the last 30 days³. A database that counts every feed ever made looks big, but most of it is dead weight for an advertiser. Always check the last episode date of any show before you email it.

What a contact database won't give you

Download numbers and rates are the show's own data. Hosts share them in a media kit when you ask. Treat any third-party listener estimate as a guess, and get the real 30-day download count from the host before you pay.

How ad marketplaces differ from podcast databases

Ad marketplaces and self-serve ad platforms are the other way to buy podcast ads. They're easy to start, but they solve a different problem.

• You buy placed spots, not relationships. Buzzsprout's ad network targets podcasts related to your business and places ads in mid-rolls. Its page doesn't say you pick the shows⁴.
• Short produced ads. Spotify's self-serve ads must be 30 seconds or less⁵. AudioGO offers ads voiced by actors or made with synthetic voices⁶. That's not a host telling listeners about your product.
• Messages stay inside. Libsyn Ads lets advertisers talk to hosts through its internal messaging system, and orders go through its sales team⁷. You don't get the host's email.
• Limited roster. A marketplace only sells shows that joined it. Libsyn Ads says it sells inventory for 1,300+ shows⁷.

A podcast database works the other way round. You choose any show in it, email the host from your own address, and agree on the read, the price and the dates yourself. You keep the relationship for the renewal.

Neither is wrong. Marketplaces are good for reach on a small budget. Databases are how you buy host reads from the long tail. Many brands use both.

The catch with the database route is the work. Finding 20 active shows in your niche and digging up an email for each host, show by show, can take days.

Podcast contact options compared

Here is how each way of reaching podcasts compares on the things an advertiser cares about.

Notice the pattern. Every ad marketplace keeps the host at arm's length. That's their business model. If you want to email a host about a 60-second read in their own voice, you need their email.

Price ranges by type of tool

Here's what it costs to get started with each route.

Self-serve ad platforms

• Podbean Ads, a $200 minimum lifetime budget per campaign⁸.
• AudioGO, budgets from $250 per campaign, with dynamic pricing and no rate card⁶.
• Spotify Ads Manager, a $250 minimum or $15 a day⁵.
• Buzzsprout Ads, 10,000 impressions for $200, down to 1 cent per impression at 100,000 for $1,000, a $10 CPM⁴.

These prices buy ad delivery. They don't include any contact with hosts.

Podcast contact databases

Contact databases charge a subscription, usually monthly or yearly, and you pay the shows separately when you book reads. Basic at $99 a month covers search, saved lists and exports. Built-in email campaigns come with Professional at $399 a month. Both cover podcasts, YouTube channels and journalists, so your podcast, YouTube and press lists live in one place.

Agencies

Agencies charge a fee or a markup on the media they buy. They're worth it for large budgets and big network shows. For a test across small and mid-size independent shows, the fee often costs more than the media.

The math for a first test

Say you test 12 independent shows at about $250 a read. At a $25 CPM, $250 buys one read on a show with 10,000 downloads per episode. That's $3,000 in media. A month of a contact database is a small add-on to that, and it's the part that lets you book the 12 shows at all.

How to judge a database's coverage

Database pages love big numbers. Big numbers don't matter. What matters is how many active, reachable shows fit your niche. Here's a quick test for any tool you're weighing.

1. List 10 shows you already know. Pick shows in your niche, from your customer survey or your competitors' sponsors. Search for each one. Count how many are there with a contact email.
2. Run your real filters. Search your category, country and language. How many shows come back with an email? Is that enough for a 10 to 20 show test?
3. Spot-check 10 results. Open each show and check that it fits your niche.
4. Look at who the email reaches. A named host or booking contact beats a generic info address.
5. Check the other channels. If you'll sponsor YouTube too, see whether the same tool covers channels, with subscriber counts you can filter on.

Red flags

• No country or language filter.
• Emails you can't export or use from your own outreach.
• Claims of exact listener numbers for every show. Only the host has those.

Is it legal to email podcast hosts

In the US, yes, when you follow the rules. The FTC's CAN-SPAM guide says the law makes no exception for business-to-business email⁹. Treat a sponsorship email as commercial email and follow these rules⁹.

• Truthful sender information that shows who sent the email.
• A subject line that matches what the email is about.
• A real physical mailing address.
• An easy way to opt out, honored within 10 business days.

Each email that breaks the rules can cost up to $53,088 in penalties⁹. So keep it clean. Use your real name and company, write a plain subject line like "Sponsoring a mid-roll on your show in March," include your address and stop emailing anyone who asks.

Rules differ outside the US, especially in the EU and Canada. Our guide on whether it's legal to email contacts you found in a media database covers the same questions for press contacts, and the logic carries over to hosts.

Be a contact hosts want to hear from

Hosts get a lot of pitches from people who want to be guests. A brand offering to pay for a read stands out. Keep the first email short, specific and clear about money, and you'll get replies.

A 30-minute workflow from search to sent

Here's how a buyer goes from zero to 20 sent rate requests in about half an hour.

1. Minutes 0 to 5, define the buyer. Write two lines on who you sell to, then pick three or four podcast categories that fit.
2. Minutes 5 to 12, filter. Search those categories in the database, set your country and language, and keep only shows with a contact email.
3. Minutes 12 to 20, check. Open each candidate and skip any show without a recent episode. Aim for 1 to 3 larger niche shows and 10 to 20 smaller ones, the mix Libsyn suggests for a first test¹⁰.
4. Minutes 20 to 23, save. Put the shortlist in a saved list with a clear name, such as "Q1 podcast test."
5. Minutes 23 to 30, send. Write one rate request with merge fields for show name and host first name. Ask for 30-day downloads per episode, audience by country, past sponsors and the price of a 60-second host-read mid-roll. Send it to the whole list.

Our podcast sponsorship email template gives you the exact wording. For more on choosing shows, see how to find podcasts to sponsor in your niche.

Then follow up once

In a study of 12 million outreach emails, one follow-up lifted replies by 65.8%¹¹. That study covered mostly link and PR outreach, but hosts are busy people too. Send one short nudge after five to seven days.

Plan the buy itself as a run, not a single spot. Magellan AI suggests 3 to 4 episodes per show over a 7 to 10 week test¹².

One list for podcasts, YouTube and press

Many brands that buy podcast reads also sponsor YouTube creators and pitch journalists. Using one tool for all three keeps your lists, contacts and outreach in one place.

• Podcasts. Hosts and booking contacts with emails, filtered by category, country and language.
• YouTube. Channels with contact emails, with a minimum-subscribers filter so you can skip channels that are too small for your test. For the YouTube side, see our guide to finding a YouTuber's business email.
• Press. Journalists by beat and outlet, for launches and announcements.

Buyers say discovery is the hard part. In IAB research on creator ad spend, about a third of brands named finding the right creators as their biggest hurdle, and "creator discovery and vetting tools" was a top area for improvement¹³. Podcasts and YouTube channels are both creators. Having them in the same searchable database cuts that work down.

If you're comparing tools for press work too, our roundup of the best media databases covers that side.

Questions, answered

What is a podcast database?

A podcast database is a searchable list of podcasts with details such as category, country, language and contact information. Databases built for advertisers include an email for the host or booking contact so brands can buy sponsorships directly.

Where can I find a list of podcasters with emails?

A podcast contact database is the fastest route. Media List lets you filter podcasts with contact emails by category, country and language, save them to a list and, on Professional, email them from built-in campaigns.

Do podcast ad marketplaces give you host emails?

Usually not. Self-serve platforms sell placed ads, and managed marketplaces such as Libsyn Ads keep buyer and host messages in their own system. To email a host directly you need a contact database or the host's own site.

How much does a podcast database cost?

Contact databases charge a monthly or yearly subscription, and you pay shows separately for the reads you book. Media List starts at $99 a month. Self-serve ad platforms instead charge for ad delivery, from about $200 to $250 per campaign.

Is it legal to email podcast hosts about sponsorships?

In the US it is legal if you follow CAN-SPAM. Use truthful sender details and subject lines, include a physical address, and honor opt-outs within 10 business days. Rules differ in other countries.

Does a podcast database show download numbers?

Not reliably. Download counts belong to the show and its hosting platform. Ask each host for average downloads per episode in the first 30 days and their audience by country before you pay.

How many podcasts should I contact for a first sponsorship test?

Libsyn suggests 1 to 3 larger niche shows plus 10 to 20 smaller ones. Email all of them the same day with the same rate request so you can compare answers.
