What is Mission Inbox?

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.

Does Mission Inbox replace Google Workspace or Microsoft 365?

No. You still use your normal mailbox to read, manage and reply to email. Mission Inbox handles the sending layer behind outgoing email.

Is Mission Inbox a sequencer?

No. Mission Inbox does not build campaigns, manage contacts or write sequences. It works underneath your CRM, sequencer, product or existing tools.

Who is Mission Inbox built for?

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.

What types of email can I send?

You can send sales outreach, marketing campaigns, product notifications, password resets, invoices, alerts and other outgoing email workloads.

What are Isolated Cubes?

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.

What is MI Shield™?

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.

Do I get dedicated IPs?

Yes. Mission Inbox uses dedicated IPs and isolated infrastructure instead of placing your sending inside crowded shared pools.

Can I see what happens after emails are sent?

Yes. You can view analytics, logs, delivery activity, bounces, sending health and performance from inside the platform.

What happens if one route has an issue?

Mission Inbox is built with redundancy across three continents. If one route has a problem, email can continue moving through another.

How fast can I get set up?

Mission Inbox is built for setup in under five minutes. You can also get help from the team if you want support getting everything connected.

Can I keep using my existing tools?

Yes. Mission Inbox can work with your current mailbox, CRM, sequencer, product or API workflow.

Replies go back to the mailbox your team already uses, so conversations stay inside your normal workflow.

Can I test Mission Inbox before connecting my own setup?

Yes. Demo Mode lets you explore the full platform with preloaded domains, mailboxes, messages, analytics and logs.

When can I send live email?

You can preview the platform in Demo Mode first. To connect your own setup and send live email, choose a paid plan and start sending.

Send emails that get seen, not just delivered.

Get pre-warmed mailboxes on dedicated IPs for your cold outreach campaigns. Mission Inbox handles deliverability, so you can focus on booking meetings and getting replies.
