How to Build a Podcast Outreach List in 10 Minutes (Using PodcastGPT)

How to Build a Podcast Outreach List in 10 Minutes — Using PodcastGPT

Building a podcast outreach list used to take hours. You would open Apple Podcasts, scroll through a category, click into each show, try to guess the audience, open a spreadsheet, manually copy details, and repeat — for 50 shows. Then half of them turn out to be dead, or the audience is completely wrong for what you are pitching.

There is a faster way. PodcastGPT lets you describe exactly what you are looking for — in plain English — and builds the list for you. With real audience demographics, chart rankings, review data, and social stats for every show. In minutes, not hours.

This guide walks you through the exact process: how to use PodcastGPT to build targeted podcast lists, how to enrich each entry with the data you need to pitch, and how to write outreach that actually gets responses — whether you are pitching sponsorships, booking guests, or finding cross-promotion partners.

Who Needs a Podcast Outreach List?

Before diving into the process, let us be clear about who this is for — because the approach is slightly different depending on your goal.

• Advertisers and media buyers — building a list of shows to buy ads on. You need audience fit, listener demographics, and chart performance data.
• PR professionals and publicists — booking your client as a guest on the right podcasts. You need active shows that take guests, in the right category, with the right audience size.
• Brands doing influencer marketing — finding podcast hosts who align with your product. You need social following, engagement, audience interests, and brand safety data.
• Podcasters looking for cross-promotion — finding similar shows in your niche for listener swaps or co-promotions. You need audience overlap and genre alignment.
• Agencies pitching podcast strategy to clients — building a research-backed show list to support a recommendation. You need data to justify every show on the list.

All five use cases follow the same core process. The difference is in the query you use to build the list and the data points you prioritize when pitching.

Step 1: Define Your Criteria Before You Build the List

The biggest mistake people make when building podcast lists is starting too broad. "Business podcasts" is not a useful brief. Neither is "health and wellness shows." A good list starts with precise criteria.

Before opening PodcastGPT, write down the answers to these five questions:

1. What genre or topic? Be specific — not just "business" but "entrepreneurship for women" or "B2B SaaS" or "personal finance for millennials."
2. What geography? Are you targeting US listeners only? UK? A multilingual audience? France, Germany, Brazil?
3. Who is the audience? Age range, gender split, income level, interests. The more specific, the better the results.
4. How large does the show need to be? Big audiences for reach plays. Small, niche audiences for conversion plays. Both have value.
5. What format do you need? Interview shows (for guest bookings), solo shows (for sponsorships), narrative series (for branded content).

Once you have those five answers, you are ready to build. The more specific your criteria, the more useful the list PodcastGPT builds for you.

Step 2: Use PodcastGPT to Build the List

Open PodcastGPT and describe what you are looking for in plain language — no filters, no menus, no configuration. Just write your criteria the way you would ask a colleague to do the research.

For Advertisers

For PR and Guest Booking

For Cross-Promotion

PodcastGPT returns each show with its CastFox analytics link, chart position, estimated listeners, and key audience data — everything you need to start evaluating the list immediately.

Step 3: Enrich Each Show With Data That Makes Pitches Land

Once you have your initial list, use PodcastGPT to go deeper on the shows that look most promising. A one-line summary is good for screening. A full data profile is what you need to write a pitch that actually gets a response.

For each shortlisted show, ask for a complete breakdown:

The key data points to capture for each show on your outreach list:

• Audience demographics — age, gender, income, geography. Use this to quantify audience fit: "Your listeners match our target customer profile exactly."
• Chart ranking trend — growing, stable, or declining? Growing shows are better pitches and more open to partnerships.
• Review count and sentiment — high reviews mean high engagement. Positive sentiment around specific topics tells you what to reference in your pitch.
• Publishing cadence — how often do they publish? Weekly shows are far better for campaign planning than monthly ones.
• Social following — does the host have reach beyond the podcast? Important for influencer marketing and branded content deals.

Explore all of this data directly on each show's CastFox analytics page. Browse the Best Podcasts rankings to see the full data available for every show.

Step 4: Prioritize by Fit, Not Just Size

The most common mistake in podcast outreach is sorting the list by download numbers and starting from the top. Big shows have high CPMs, low response rates, and often the worst audience fit for niche products.

Instead, rank by audience fit — a composite of how well the listener demographics match your target, how actively the show is growing, and how engaged the audience appears based on reviews and social presence.

Use PodcastGPT to compare shortlisted shows side by side:

Tier your final list into three buckets:

• Tier 1 — Dream list: Perfect audience fit, strong growth, highly engaged listeners. Priority pitches. Spend the most time personalizing these outreaches.
• Tier 2 — Strong matches: Good audience fit, stable performance. Send personalized but slightly templated pitches.
• Tier 3 — Reach outs: Decent fit, worth trying at volume. Use a lighter-touch, templated approach.

Track how your target shows perform over time using CastFox Charts and CastFox Alerts — get notified when a show you are targeting hits a chart milestone or drops in rankings.

Step 5: Write the Pitch — What to Include and What to Skip

Most podcast outreach fails because it is generic. Hosts and booking teams receive dozens of pitches a week. The ones that get responses prove the sender actually knows the show.

Use the data PodcastGPT gave you to write pitches that are specific and relevant.

For Sponsorship Pitches (Advertiser to Podcast)

1. Reference the show specifically — mention a recent episode topic. This proves you actually listened, not just scraped a list.
2. Match the audience to your product — use the demographics data directly: "Your listeners skew 35-50, high-income, interested in investing — that is exactly our target customer for [product]."
3. Propose a specific ad format — host-read mid-roll, sponsored segment, dedicated episode. The more specific the ask, the easier it is to say yes.
4. Name a number — propose a CPM or flat fee based on their chart position and listener estimates. Hosts respect advertisers who have done the research.

For Guest Booking Pitches (PR to Podcast)

1. Reference the host's recent content — use the episode data from PodcastGPT: "I noticed your last three episodes focused on scaling beyond $1M — my client just took a company from $0 to $5M in 18 months."
2. Frame the value for this specific audience — use the audience demographics to justify the fit: "Your listeners are aspiring entrepreneurs — [client] has a story they will immediately connect with."
3. Keep it short — three paragraphs maximum. Hook, value, ask. Anything longer gets skipped.
4. Include social proof — previous podcast appearances, audience size, notable mentions. Hosts want to know the guest can hold an interview.

For Cross-Promotion Pitches (Podcaster to Podcaster)

1. Lead with complementarity — "Our audiences do not overlap much geographically, but we cover the same topics." This frames the swap as a win-win, not a competition.
2. Show your numbers — chart position, episode frequency, listener count. Use CastFox data to present your show professionally.
3. Propose a specific format — ad swap, guest swap, or co-release. Vague asks get vague responses.

Three Real-World Scenarios: From Query to Pitch

Scenario 1: A Fintech App Advertising on Podcasts

A mobile investing app wants to reach 25-40 year olds in the US who are new to investing. Their target CPM is $30 and they need 8 shows for a 3-month campaign.

PodcastGPT query: "Find 15 US personal finance and investing podcasts with audiences aged 25-40, skewing toward beginners rather than advanced investors, ranked by chart position"

Result: A ranked list of 15 shows with audience age breakdowns, chart positions, and estimated listener counts. They identify 8 shows in their budget range, use PodcastGPT to get full demographic profiles on each, and build a campaign proposal in an afternoon instead of a week.

Browse investing and personal finance podcasts on the US Business Charts or CastFox Best Podcasts.

Scenario 2: A PR Agency Booking a Startup Founder on 10 Podcasts

A PR agency has a founder client launching a book about remote work. They need 10 podcast appearances in 60 days — shows reaching managers and executives primarily in the US and UK.

PodcastGPT query: "Find business and leadership podcasts in the US and UK that regularly feature guest interviews, published in the last 30 days, with audiences of managers and executives"

Result: A list of active, bookable shows with audience composition data. The agency enriches the top 15 with individual show breakdowns, writes 15 personalized pitches over two days, and books 8 appearances — a 53% response rate compared to their usual 20%.

Scenario 3: A French Podcast Expanding to English-Speaking Audiences

A French entrepreneurship podcast with 50,000 monthly listeners wants to grow its English-speaking audience. They need English-language shows with overlapping content but minimal existing French listener overlap.

PodcastGPT query: "Find English-language entrepreneurship podcasts that do not have significant French audience overlap, ranked by listener count"

Result: A list of English shows with geographic audience breakdowns — making it easy to identify shows where a mention would reach a genuinely new audience. They contact 10 shows, arrange 4 listener swaps, and grow English listenership by 15% in 60 days.
