For growing teams

Grow your sending without redoing setup

Add mailboxes, domains and a second provider as you grow. Arcinbox sets up everything new the same way and watches it on the same screen.

The problem

Every step up means starting over

Going from one provider to two, or from a hundred mailboxes to a thousand, usually means new tools and new setup.

A second provider is a second project

Microsoft works differently from Google, so the second provider waits for a quiet month that never comes.

More mailboxes, more to watch

Every hundred new mailboxes is another hundred things that can quietly break.

The bill grows faster than the team

Warmup, monitoring and DNS each arrive as another subscription as the fleet grows.

How Arcinbox grows with you

Add more, set up the same way

New mailboxes, domains and providers come through the same order and land on the same screen.

Microsoft next to Google

A Microsoft mailbox costs what a Google one does, and Arcinbox sets it up the same way, in the same order.
