Your list grew. Your bill shouldn't.
Substack grew your audience. Now take them with you.
Substack is a great place to start writing. But every paid subscriber goes through Substack's billing (10% cut), and your audience is rented, not owned. Senderkit gives you the list, the sending infrastructure, and 100% of the revenue.

Why teams start looking elsewhere
Three bills that climb faster than your open rate.
10% of revenue forever
Every paid subscription has Substack's cut baked in for life. Growing to 1K paid subs at $10/mo? That's $12K/year out the door — just in platform fees.
Shared audience, shared brand
Substack promotes its network — sometimes to your subscribers. The reader relationship is mediated by the platform, not owned by you.
Everything lives on substack.com
Posts, comments, recommendations — all hosted there. If you ever want to move, migrating subscribers is easier than migrating brand equity.
What changes on day one
Same audience. Different economics.
