Unibox overview
Last updated: April 24, 2026
Unibox is Stamina's unified reply inbox. Every response from every lead, across every connected sending account, appears in a single view. You manage the full conversation — reply, update status, add labels, set reminders — without leaving the platform or switching between email accounts.
