"I've been publishing for 6 months. I don't know who's reading. I don't know why growth stalled. I'm starting to think maybe I'm just not meant for this."

— Every Substack creator at 3am

Open your dashboard. See exactly which 47 subscribers are ready to become paid.

You've been building in the dark. StackContacts shows you the subscribers who click every link, read every post, and are waiting for you to ask. They're already in your list. They've been ready for weeks. You just couldn't see them until now.

Show Me Who's Ready

You're not bad at growing. You've been flying blind.

Substack shows you vanity numbers. Total subscribers. Open rates. View counts that don't match anything.

But it never shows you the 47 people who clicked 5+ links last month. Or the 12 readers who comment on everything but haven't upgraded. Or the exact moment your best subscriber stopped opening emails.

You've been making decisions about your audience without actually knowing your audience. That's not a skill problem. That's a visibility problem.

And now you can fix it.

Ask anything. Get answers you can act on.

"Show me everyone who clicked 3+ links but never left a comment"

→ 23 subscribers found. These are your lurkers who engage deeply but silently. Perfect for a "I noticed you've been reading..." outreach. Three of them have been subscribed for 8+ months.

"Who opened every email last month but isn't a paid subscriber?"

→ 47 subscribers found. Your warmest leads. They read everything you write. They just haven't been asked to upgrade yet. Sort by engagement score to prioritize.

"Which subscribers stopped opening emails in the last 30 days?"

→ 156 subscribers at risk. These people used to engage. Now they're slipping away. You have a window to re-engage them before they're gone. Here's exactly who they are.

You already know this is true

One promise: You'll finally know your audience.

Not "have better analytics." Not "see more metrics." You'll know who's reading, who's engaged, who's ready to pay, and who's about to leave. Every feature exists to answer one question: Who should I talk to next, and what should I say?

Know who's ready to pay

Not everyone is ready to upgrade. But some people are. StackContacts shows you who's been engaging for months without converting—your warmest leads, sorted by how ready they are to become paying subscribers.

Catch subscribers before they leave

Someone who opened every email for 6 months just stopped. You have maybe 2 weeks before they're gone forever. StackContacts flags at-risk subscribers so you can re-engage them while there's still time.
