FAQ

Questions, answered straight

How accurate is the spam trigger score?

It's a weighted match against a list of phrases known to hurt inbox placement, not a live inbox-placement test — no third-party tool (including ours) can guarantee exactly what Gmail or Outlook will do with a given email. Treat a high score as "worth rewriting this line," not as gospel.

Which ESPs can I connect?

beehiiv, Kit (formerly ConvertKit), and Substack today. The connection is read-only — we pull your subscriber count and open rate to verify your reach, and nothing else.

Is the ESP connection safe? What do you do with my API key?

Your API key is encrypted at rest (AES-256-GCM) before it ever touches the database, and it's only decrypted server-side at the moment we sync your stats. We never request write access — there's no scope in our integration that could let us send on your behalf or change your account.

How do you decide who I get matched with for a swap?

Effective reach — your subscriber count times your open rate — compared to other newsletters in the same niche, within 20% of yours in either direction. That's it. No manual curation, no paying to rank higher.

What actually happens when I request a swap?

The other creator gets your request along with a generated tracking link. What you agree to do with each other — when to send, what to say — happens between the two of you; we're the matchmaker, not the middleman.

What happens to my data if I cancel?

Your newsletters, audit history, and swap requests stay in your account — cancelling just drops you back to the Free tier's limits. Nothing gets deleted unless you delete it yourself.

Do you have an API?

Not yet. If that's something you need, the /features page's checks are all built from a self-contained module — reach out and it's worth discussing.
