7 Must-Have Podcast Guest Databases & Outreach Tools

What Are Podcast Guest Databases and Outreach Tools?

Podcast guest databases are searchable directories of shows that let you filter by topic, audience, and activity. Outreach tools are the email and matching products you use to pitch hosts and track replies. Together they form the stack most guests use to get booked.

This guide groups seven tools into three layers. Discover tools such as Rephonic, Podchaser Pro, and Listen Notes find shows. Match platforms such as PodMatch and MatchMaker.fm connect you with hosts who want guests. Reach tools such as Hunter and GMass find email addresses and send follow-ups.

How Many Podcasts Can You Actually Pitch?

Far fewer than database headlines suggest. Listen Notes lists 3,821,864 podcasts and 195,426,542 episodes as of October 3, 2026, but only 563,571 podcasts show their last activity in 2026. That is roughly 14.7%, a rough year-to-date proxy rather than a rolling measure.

Inside Radio, reporting Listen Notes data in March 2026, put active shows at 391,394, up from 314,452 a year earlier. Meanwhile new launches fell from a peak of 1,020,499 in 2020 to 210,960 in 2025. Headline counts also differ by vendor: Rephonic cites more than four million shows, while roundups put Podchaser between 5.5 and 6 million. Each tool counts differently, so never compare size alone.

What Do Most Podcast Tool Roundups Leave Out?

The roundups that rank for this topic share four weaknesses. Several come from companies that sell a booking or listening product, and one ranks its own platform first. One has no publication date. Most give prices for only a few tools, and the figures conflict, such as Podchaser Pro priced at about $2,500 a year in one place and up to $5,000 in another.

The biggest gap is that none explain that database size counts dormant shows. A tool that returns 4,000 matches is not giving you 4,000 pitchable hosts. The framework below turns that problem into a repeatable filter.

How Do You Qualify a Show? The Pitchable Show Check

The Pitchable Show Check is a five-step filter you run on every show before it enters your pitch list. A show passes only if it clears all five, which removes dormant and mismatched shows early.

1. Recent episode. The latest episode is under 30 days old. Skip anything quieter, because a dormant show cannot publish your episode.
2. Guest format. Past episodes include outside guests. Solo shows cannot book you.
3. Audience fit. The listener profile matches the buyers or readers you want, not just the topic.
4. Verified contact. You have a host or booking email from a source you can check, not only an export.
5. Pitch angle. You can name one past episode and say what your guest topic adds to it.

Reviewing podcast outreach across client work points to a recurring mistake: pitching straight from a database export without opening a recent episode first. The check prevents it, and it works with any tool below.

Which Podcast Guest Databases and Outreach Tools Are Worth Using?

Prices below are vendor-listed unless marked reported.

1. Rephonic: Best Paid Database for Research and Pitch Tracking

Rephonic covers more than four million podcasts with listener demographics and contact details for pitching. Plans run $99, $149, and $299 per month, each with a 7-day trial. Search quotas are shared across a team, so the $99 Light plan’s 100 monthly searches suit solo use.

2. Podchaser Pro: Best for Demographics and Sponsorship Data

Podchaser Pro adds listener demographics, contacts, sponsorship intelligence, and exports in CSV, XLSX, and PDF. It publishes no price. A competitor’s blog reports about $2,500 to $5,000 per year from an unnamed source, so request a quote. It does not cover the outreach workflow, so pair it with an email tool.

3. Listen Notes: Best Free Search Index

Listen Notes is an independent podcast search engine with 3.8 million podcasts and about 195 million episodes. It has a free tier for manual searching, and a Pro plan is reported near $200 per month. It will not give you pitch tracking, so use it to find shows and check recent episode dates.

4. PodMatch: Best for Inbound Host and Guest Matches

PodMatch suggests host and guest candidates using topics, experience, and audience size, then manages booking in the platform. Guest plans are listed at $32 and $64 per month by two third-party reviews, and there is no free tier. It only reaches hosts who joined, so treat it as a supplement.

5. MatchMaker.fm: Best Low-Cost Matching Option

MatchMaker.fm uses profiles with video pitches and suggests matches weekly, with an inbox and scheduling-tool integration. Its page lists a 30-day free trial and then $15 per month, with five outbound conversation starts during the trial. Its member counts are self-reported and inconsistent, so test before relying on it.

6. Hunter: Best for Finding Host Email Addresses

Hunter’s Email Finder returns a professional’s email address and charges one credit per address found. The Free plan includes 50 credits monthly and Starter is $49 per month. Verification uses half a credit per email, so budget credits for checking addresses as well as finding them.

7. GMass: Best for Follow-Up Sequences Inside Gmail

GMass runs inside Gmail as a mail merge tool with open, click, and reply reports. Sequences and automatic follow-ups start on the Premium plan at $39.95 per month, or $29 monthly on annual billing. Follow-ups matter because one pitch rarely earns a reply.

GMass	Reach	Gmail mail merge and follow-ups	$29.95 to $59.95 per month

Which Stack Should You Build?

A solo guest can start with Listen Notes, MatchMaker.fm, and Hunter’s free plan, then add GMass for follow-ups. A consultant pitching weekly should add Rephonic for contacts and demographics. Agencies managing several clients may need Podchaser Pro, but get a quote first because it has no public price.

Frequently Asked Questions

What is a podcast guest database?

A podcast guest database is a searchable directory of shows that lets you filter by topic, audience size, and recent activity, and often returns host contact details. It supports research rather than booking, so most people pair it with an outreach tool to send pitches and track replies.

Which database is best for finding podcast guest spots?

It depends on your budget and whether you need contact data. Rephonic and Podchaser Pro are the paid options most often compared, while Listen Notes offers a free tier for manual searching. Start with the free tier, then pay only when searching by hand costs more time than a subscription.

Are podcast guest matching platforms worth paying for?

They are cheaper than databases, but they only reach hosts who joined. PodMatch lists guest plans at $32 to $64 monthly, and MatchMaker.fm lists $15 monthly after a 30-day trial. Use them for inbound matches, and use a database when you want shows that never signed up.

How many podcasts are actually active?

Far fewer than the totals suggest. Listen Notes indexes about 3.8 million podcasts, yet reported 391,394 as active in 2026 when Inside Radio covered its data in March. Dormant shows inflate every database headline, so filter by recent episode dates before you build a pitch list.

How do you find a podcast host’s email address?

Check the show’s website and the contact fields in your database first. If neither works, Hunter’s Email Finder returns professional addresses and charges one credit per address found. Its free plan includes 50 credits monthly. Verify the address before sending, since bounced emails hurt deliverability.

How much does a podcast database cost?

Rephonic lists plans from $99 to $299 monthly with a 7-day trial. Podchaser Pro publishes no price, and third-party ballparks range from about $2,500 to $5,000 yearly. Listen Notes has a free tier, with its Pro plan reported near $200 monthly. Confirm every figure with the vendor.

Where This Fits Into a Broader SEO Strategy

Podcast appearances earn show-notes links, brand mentions, and referral traffic, which support wider link building and authority goals. Stay Digital Marketers assists brands with backlink-related services, including guest posting, press release distribution, SaaS backlinks, niche edits, multilingual backlinks, Wikipedia page creation, Google Knowledge Panel creation, and complete SEO services.
