How to get space YouTubers to promote your learning app
- 1
Start with 20–30 good fits
Pick creators whose recent videos match what you made, who posted in the last month, and whose typical views are steady. Mid-size and small channels reply far more often than the biggest ones.
- 2
Write to each one personally
Mention a recent video of theirs, say in one line what your learning app is and why their audience would care, and make the offer clear: free access, a fee, or both. UGC Finder writes this email for every creator.
- 3
Follow up once, then track it
Creators get a lot of email. A short, friendly follow-up after a week is normal. Cross off who you've contacted so you (and your team) never email the same person twice.
Questions

45 space creators right now, with 107M subscribers between them. New channels are added every day and every profile is refreshed from YouTube regularly.
How do I contact space YouTubers?

Should I pick big or small space channels?
47% of the space creators here have under 100K subscribers. Smaller channels usually answer more often, cost less or nothing for a free learning app, and their audiences trust them, so they're a good first wave. Filter by audience size to find them.
Can I find space creators who make Shorts or long videos?
Yes. 24 mostly post long videos and 12 mostly post Shorts. Long videos suit a proper review or playthrough; Shorts get quick reach. You can also filter by country, language and whether they posted in the last 30 days.
