Frequently Asked Questions
How is this different from the master inbox built into Instantly or SmartLead?
Sequencer-based inboxes pull replies through their own sync cycle—which can range from 1 minute to 60 minutes depending on the platform. We connect directly to your mailboxes via Gmail and Outlook APIs. Replies appear in seconds, not minutes. And because we're not dependent on your sequencer, we never miss a reply that they failed to capture.
Which email providers do you support?
We currently support Gmail (including Google Workspace) and Outlook (including Microsoft 365) via native API connections, and any email provider with IMAP/SMTP.
Which cold email platforms does this work with?
All of them. Instantly, SmartLead, Smartreach, Lemlist, EmailBison, Apollo—it doesn't matter. We connect to your mailboxes directly, not through your sequencer. However you're sending, we'll catch the replies.
How does the AI classification work?
Every incoming reply is analyzed and automatically sorted into labels. The difference: you define what those labels are and what they mean. Create your own categories (Demo Request, Objection, Referral, Not Now, etc.) and customize the AI logic behind each one. Your classification rules, running on autopilot.
Can my whole team use this?
Yes. Add unlimited team members, control permissions, and see who's handling which replies. Everyone works from the same inbox—no more "I thought you were handling that" moments.
Can I try it before paying?
Yes. Start a 14-day free trial with no credit card required. Connect your mailboxes and see every reply in real-time before you commit.
