Podcast & Newsletter Prospector

Find podcasts and newsletters for B2B outreach. Search Substack and Apple Podcasts by keyword to discover potential sponsorship opportunities, guest post targets, and partnership leads.

What does it do?

This Actor searches two platforms to find relevant podcasts and newsletters for your B2B outbound campaigns:

• Substack — Searches for newsletters and publications by keyword
• Apple Podcasts (iTunes Search API) — Finds podcasts by keyword

The Actor enriches results with contact information where available, including email addresses from RSS feeds and author profile links.

Perfect for sales teams, marketing agencies, and users of tools like Clay.com who need to build prospect lists for podcast sponsorships, guest posts, and strategic partnerships.
