Do I get a dedicated IP for every Cube?

Yes. Each Cube runs on its own server instance with its own dedicated IP, separate from every other Cube on your account and every other Mission Inbox customer.

Can I add more Cubes as I grow?

Yes. You can add a new Cube whenever you start a new workload or need to separate an existing one further, without affecting Cubes already running.

Does a problem in one Cube affect the others?

No. Cubes are fully isolated at the server and IP level, so a reputation issue in one Cube has no path to reach another.

What's the difference between a Cube and a mailbox?

A Cube is the underlying dedicated server instance and IP your email sends from. Mailboxes and domains sit on top of a Cube.

Infrastructure / The Cubes

Your own server. Not a slice of someone else's.

Send through isolated server instances and dedicated IPs instead of sharing reputation with unknown senders. Sales, marketing, transactional and financial email stay separate. Scale from 10K to 30M sends without touching anyone else's reputation.

The Status Quo

Every company runs 3-4 email vendors. Out of fear.

With shared infrastructure, one workload poisons another.
A marketing blast can kill password-reset delivery.

Contracts

Dashboards

Support queues

people who can tell you if the email arrived

Engineering

Transactional ESP

Password resets, receipts, 2FA codes

Fails silently. You find out from a support ticket.

Growth

Marketing ESP

Campaigns, newsletters, lifecycle

Highest volume, lowest scrutiny. One bad list burns the domain.

Sales

Sales Outbound tool

Cold sequences, prospecting

Cold outreach on the same domain as your receipts.

Compliance

Mail gateway

Archiving, DLP, filtering

Adds a hop and latency to everything above it.

Fragmentation is the only defense.
4 reputations, 4 failure points.

Cubes give you that same isolation, without the four vendors.
One platform, one contract, and a dedicated Cube for every workload.

How Cubes work

Infrastructure that scales with you, not against you.

Dedicated IPs & Server Instances

A server that's actually yours

Every Cube runs on its own server instance with its own dedicated IP. Nothing about your sending infrastructure is shared with another Mission Inbox customer.

Your own dedicated IP, never pooled

Isolated server instance, no shared tenancy

The reputation you earn stays yours

Workload Isolation

Sales, marketing, transactional and financial email, kept apart

Each workload runs in its own Cube. A spike in outbound volume or a flagged campaign in one Cube has no way to reach the others.

Start on one workload, grow to millions

No re-platforming as volume climbs

Same setup from first send to 50M+

Scaleable

From 10K to 50M+ monthly emails

Cubes scale with your sending volume. Start small on a single workload and grow into tens of millions of monthly sends without re-platforming or renegotiating your setup.

Transactional stays safe from marketing risk

Separate sending reputation per workload
