01 / Folder profiles
Folders you define, in plain English
Tell Zerrow what belongs in each folder — receipts from Stripe, cold sales pitches, calendar invites from clients. The AI handles the rest. No filter rules, no regex.
For Gmail·powered by AI
An inbox
that sorts
itself.
Zerrow reads every new email and files it into the folders you actually use — newsletters, invoices, cold pitches, calendar invites — so the only thing left in your inbox is what deserves your attention.

Questions, answered.
Everything you need to know before you hand Zerrow the keys to your inbox.
Q.01Does Zerrow store my emails?+
Zerrow syncs message metadata and content so it can classify and summarize. Everything is scoped to your account, and you can disconnect Gmail at any time from Settings.
Q.02Will it move emails in Gmail itself?+
Yes — when Zerrow files an email into a folder, it applies the matching Gmail label so your phone, web, and other clients stay in sync.
Q.03What if it gets it wrong?+
Move the email to the correct folder and Zerrow learns from it. The next time a similar email arrives, it routes correctly. You can also hit Reanalyze on any single message.
Q.04Which mail providers are supported?+
Gmail and Google Workspace today. Other providers may come later.
