YouTube is unusual among the platforms Outsoci covers: a large share of channels publish a business email on purpose, because creators want brand deals to reach them. Search by niche or keyword and Outsoci pulls channel details, subscriber counts, and that business email straight from the About page. It's the fastest way to build a sponsorship or affiliate outreach list without opening a hundred channel pages by hand.
Describe who you want — job title, niche, business type — plus an optional location.
Outsoci searches live and pulls matching profiles and their public contact details.
Emails are verified and deduplicated, then exported to a clean CSV in one click.

Volume ceiling. About 1,000 channels per niche keyword run. This is the highest email-match platform Outsoci covers — 45–65% of monetization-minded channels expose a business-inquiries address, and the linked-site fallback recovers a further slice.
YouTube's About page has a “business inquiries” contact option that creators can turn on specifically so brands and agencies can reach them — this is the single most direct email source of any platform Outsoci covers, and it's opt-in by design rather than something to be worked around.
Where a channel hasn't published that address, the fallback is the same pattern as everywhere else: crawl the linked sites in the description and About page for a contact email. Many creators run a personal site, a Patreon, or a merch store that lists one even when the channel itself doesn't.
Search works by keyword and niche rather than location — "productivity software reviews" or "home renovation DIY" surface the channels actively publishing in that space. Subscriber count then lets you decide whether you want reach (larger channels) or engagement and affordability (smaller, more niche ones).
One quirk worth knowing: a channel's subscriber count and its actual value for sponsorship purposes can diverge — a smaller channel producing tightly-niche, highly-engaged content often converts better for a sponsor than a much larger, more general one. Use subscriber count as a first filter, not the only one; the channel description and recent upload cadence tell you more about how active and relevant a channel currently is.
The business-inquiries email is built for exactly this — pitching a sponsorship, affiliate deal, or product review directly to the channel owner.
Software companies find channels in adjacent niches (tutorials, reviews) to seed with free accounts or paid integrations.
Sourcing guests or speakers by niche and subscriber count before reaching out with a booking pitch.
Building a roster of channels across several niches for a client's always-on influencer budget.
Channels that teach a skill (coding, design, trades) are natural affiliates for tools used in that exact workflow.
Do YouTube channels really show a business email?
Many do — the About page has an opt-in "business inquiries" contact field creators enable specifically so brands can reach them. It's the most direct email source among the platforms Outsoci supports.
What if a channel doesn't show a business email?
Outsoci falls back to crawling any linked sites in the channel's description or About page — a personal site, Patreon, or store often lists a contact address.
Can I filter by subscriber count?
Yes — every channel comes back with its subscriber count, so you can target micro-channels, mid-size creators, or established channels depending on your budget and goal.
Is this different from the official YouTube Data API?
The official API is built for app development, not bulk lead sourcing, and has its own quota limits. Outsoci is purpose-built for finding and validating creator contact emails.
How current is the subscriber and email data?
Searches run live at request time against the channel's current public About page, not a cached or resold list.
Is scraping public YouTube channel data legal?
Channel names, descriptions, and opt-in business emails are public information creators choose to display. Your outreach still needs to follow CAN-SPAM and similar rules.
Can I filter by niche or content category?
Yes — keyword search against channel names and descriptions lets you target a specific content category directly, from software reviews to home renovation to fitness coaching.
Does this cover Shorts-focused channels as well as long-form?
Yes — the search works off channel-level data (About page, description, subscriber count), so it covers channels regardless of whether they primarily post Shorts or long-form video.
Can I build a list across multiple niches at once?
Yes — run separate keyword searches per niche and merge the exports, the same batching approach that works for multi-city Google Maps searches.
Is scraping public YouTube About-page data compliant?
The business-inquiries email is explicitly opt-in and public by the creator's own choice, which puts it on solid footing — your outreach still needs to follow CAN-SPAM.
