PodcastGuests.com

PodcastGuests.com has been quietly running one of the simplest and most effective free tools in the podcast booking space: a twice-weekly email featuring podcasts looking for guests in different niches. Sign up for free and you get 1-2 emails per week with roughly 10 opportunities each, and you pitch yourself directly to the hosts that look like a match.

No middleware, no marketplace fees, just a directory of open shows. The paid product is a Premium Listing in the expert directory at $29/month, which puts you in front of podcast hosts actively searching for guests.

The platform claims over 46,000 experts in the network and has been operating for years, which gives it the kind of liquidity these directories live or die on. For a guest with budget constraints, the free newsletter is genuinely the entry point: you'll spend a few minutes a week scanning opportunities and pitching the ones that fit.

Conversion depends entirely on the quality of your pitch and topic fit, but it costs nothing to try. The $29/month upgrade is worth it once you've validated the channel and want hosts coming to you instead of the other way around.

For hosts looking for guests, the platform is less compelling, the directory model works but more recent tools like Podzay (AI-powered matching, free) and PodMatch (subscription with AI) are arguably better-shaped for the host side. PodcastGuests.com remains the best free pure tool for the guest side of the equation.
