Substack gives you an inbox. ChatStack makes it work. Labels, search, filters, and favorites — so every conversation gets the the attention it deserves.
When your audience grows, your inbox becomes a black hole. Here's what that looks like.
New subscriber? Old reader? Random spam? Every thread looks identical. There's no way to tell what matters.
Someone mentioned a collab three weeks ago. Or was it four? There's no search. You're scrolling forever.
No labels. No folders. No way to separate your VIPs from the noise. It all piles up the same way.
The reader who's been with you for two years messaged you. You'll get to it. You won't.
Label every conversation the way you want. Paying subscribers, potential collabs, press inquiries, superfans — you decide the system. ChatStack holds it.
Type a name. Type a word. ChatStack finds it. Your entire DM history is searchable — not just the last 10 threads Substack shows you.
Filter to Unread and your inbox goes from overwhelming to manageable. Work through it systematically. Nothing falls through the cracks.
Hit Sync and ChatStack pulls everything in. Your conversations are always current. No manual checking, no wondering if you missed something.
From creators who were drowning in DMs and needed a real system.
Labels changed everything. I can finally tell collaborators apart from one-off replies, and the unread filter means I never re-read a thread twice.
I found a collab thread from three months ago in two seconds. On Substack that message was gone forever. ChatStack made my whole inbox searchable.
Unread filters and labels turned chaos into a system. I work through one category at a time and nothing slips through. It feels like the inbox Substack should have shipped.
Everything you need to manage your Substack inbox. No hidden fees.
ChatStack gives you the inbox Substack should have built.
