Every reply from every mailbox. One screen.
Manage 200 mailboxes' worth of replies from one inbox — without juggling 200 logins, sharing app passwords, or losing context.
The 200-logins problem
Scaling cold email means scaling mailboxes. Scaling mailboxes means scaling logins, app passwords, browser profiles, and human error. The unified inbox makes that operational tax go away.
Team access without passwords
VAs and SDRs reply through the unified inbox using their own CLAYINBOX account. They never see mailbox credentials. Audit trail per reply, per user.
Works alongside sequencer master inboxes
Smartlead and Instantly have master inboxes for campaigns — ours covers everything else: standalone mailboxes, paused campaigns, replies that arrive after a sequence ends, and the whole non-campaign workflow.
