Message Crystal
How it works
Simple for you.
Useful for your audience.
Your subscribers download the app once. After that, every crystal notification you send lands in their pocket — filtered by their own preferences.
Share your Crystal link
Drop your custom URL on YouTube, Twitter, Instagram — anywhere. Followers tap once to subscribe. No email required.
Subscribers set preferences
They choose what to receive — new videos, podcast appearances, collabs, deals. They control frequency. You see exactly what they chose.
Send smart notifications
Write a notification manually, or email a link and let our AI draft one for you. Review, edit, send. Done in under two minutes.
Read the intelligence
Your Crystal Preferences Report shows which content types your audience wants most. Stop guessing your content calendar — start knowing.
Cross-pollination
Your YouTube audience doesn't know you have a podcast.
Every creator with 100K+ followers has at least two platforms. Most of the time, your audience on one has no idea about the other. Message Crystal bridges that gap without asking them to subscribe to anything new.
When a subscriber opts into your Crystal, they get a single, curated feed across everything you make — filtered to exactly what they care about.
- Subscribers choose which platforms and content types to follow
- They can mute entire categories (e.g. already reading your Substack)
- Exception alerts cut through: “I was on a podcast you'll love” — only lands if they asked for it
- You reach an audience you didn't know was waiting on another channel

Common questions
What's a “crystal” — and why would my audience want one?
A crystal is what your subscriber holds: their personal, filtered window into your content. Instead of getting every notification from every creator they follow, they choose exactly what types of content matter to them. It's the control their phone's notification settings never actually gave them.
Do my subscribers need to give me their email address?
No. That's the point. Subscribers download the Message Crystal app once — free, always — and subscribe to your crystal with a tap. No email, no login friction, no spam folder. You get an owned channel without asking for anything invasive.
My followers already get YouTube notifications. Why would they also subscribe to my Crystal?
Platform notifications are all-or-nothing and platform-controlled. Your Crystal lets subscribers choose which of your content they want — across all your platforms — at whatever frequency they prefer. A subscriber who's already watching your YouTube videos can opt in to podcast appearances only, and skip everything else. That's a level of control no platform offers.
What does “Crystal Preferences Report” actually show me?
It shows you the percentage of your subscribers who opted into each type of content, their frequency preferences, and which segments are most engaged. If 73% of your subscribers opted in for podcast appearances but only 28% want merch notifications, you finally have signal — not guesswork — to guide your content and business decisions.
How does AI notification creation work?
On Basic and above, you email a link — a YouTube URL, a podcast episode, an article — to your Message Crystal backend. The AI drafts a short, subscriber-friendly notification. You review it, edit if needed, and send. Most creators finish in under two minutes.
Is this worth $10/month?
If you have 100,000 followers and earn $5,000/year from your content, reducing subscriber churn by 2% covers the cost of Basic entirely. The Crystal Preferences Report — knowing exactly which content your audience wants — tends to do considerably more than that.
Stop flying blind.
Start understanding your audience.
Most creators spend years building an audience, then spend more years guessing what that audience wants. Message Crystal turns your guesses into data — starting free, from day one.
