Clear answers on setup, infrastructure and how Mission Inbox fits into your existing workflow.
Mission Inbox is the sending infrastructure behind outgoing email. It helps teams send sales, marketing, transactional and product emails through dedicated infrastructure built for volume and inbox placement.
No. You still use your normal mailbox to read, manage and reply to email. Mission Inbox handles the sending layer behind outgoing email.
No. Mission Inbox does not build campaigns, manage contacts or write sequences. It works underneath your CRM, sequencer, product or existing tools.
Mission Inbox is built for teams that rely on outgoing email, including sales teams, agencies, marketing teams, platforms, developers and businesses sending transactional or financial email.
You can send sales outreach, marketing campaigns, product notifications, password resets, invoices, alerts and other outgoing email workloads.
Isolated Cubes are separate sending environments for different workloads. Sales, marketing, transactional and financial email can each run separately so one stream does not damage another.
MI Shield checks content, headers, DNS and spam signals before emails are sent. It helps catch risky emails before they damage your domain or reputation.
