How it works
Four steps from a new domain to a warm, export-ready mailbox
No spreadsheets of mailboxes, no manual setup per account, no guessing when a sender is ready. Domains, mailboxes, warm-up and export run from one platform.
- 1
Connect your domains
Add your domains and manage them from one dashboard. Each domain holds up to 3 mailboxes, or up to 5 on plans of $1,000 and above.
One dashboard - 2
Set up the mailboxes
Buy mailboxes through Infrabox or connect Google Workspace, Microsoft Outlook, Microsoft Azure and custom mailboxes. Setup is automated, not one at a time.
Automated setup - 3
Warm up on our network
Each mailbox exchanges email with our warm-up network to build sender reputation. We recommend at least 2 to 3 weeks before you start sending.
2-3 weeks min - 4
Export, then watch
Select mailboxes, choose your sequencer, export and track progress. Email Insights then shows sent, received, reply rate, bounces and health.

InfraGuard add-on
Reputation slips quietly. InfraGuard catches it.
By the time replies dry up, the cause is usually weeks old. InfraGuard monitors the health and reputation of every domain, so infrastructure issues show up before they affect deliverability.
Domain score and protection
Every domain gets a health score, so you can see at a glance which ones are strong and which need attention before they hurt a campaign.
Blacklist monitoring
Domains are watched against blacklists, so a listing shows up in your dashboard instead of in a falling reply rate.
DNS checks
The records your sending depends on are checked for you, so a broken or missing record is caught before it costs you placement.
Bounce and IP / IPT monitoring
Bounce rates and IP / IPT signals are tracked per domain, so infrastructure-level problems surface early.

Early customers
Early teams. First results.
Agencies, outbound teams and founders who set up their email infrastructure on Infrabox since launch in September 2026.
“We were setting up mailboxes for every new client by hand. In our first weeks on Infrabox, the domains, mailboxes and warm-up for a new client were ready from one dashboard.”
Priya RamanHead of Delivery, Northloop“Inbox Placement showed us how much was going to spam before we launched. We fixed it during warm-up instead of finding out from a dead campaign.”
Marcus KellFounder, Reachpilot“InfraGuard flagged a domain with a DNS problem on day two. I would not have caught that until the bounces started.”
Ana TorresGrowth Lead, Signalcrest“Having up to 5 mailboxes per domain on our plan made the maths work for us. Everything for each client sits in one view.”
Devon ShawOperations Director, Vantage Grid“Export is the part I expected to be painful. Select the mailboxes, pick the sequencer, export, and the progress is right there.”
Iris NakamuraPlatform Engineer, Kestrel Labs“Email Validate cleaned out the catch-alls and dead addresses before our first send. That is the list hygiene we kept putting off.”
Tomas WeberDemand Gen, Orbitline“We connected our existing Google Workspace and Outlook mailboxes and put them on warm-up the same afternoon. $3 a mailbox is an easy yes.”
Lena FitchOutbound Manager, Pipeworks“Email Insights puts sent, received, reply rate and bounces for every mailbox on one screen. I stopped exporting reports to spreadsheets.”

If the answer you need is not here, it is probably specific to your setup. Ask the Infrabox team.
Infrabox is an email infrastructure and automation platform, launched in September 2026. It brings domain management, mailboxes, email warm-up, export to your sequencer and email insights into one platform, with InfraGuard, Email Validate and Inbox Placement as add-ons.
Up to 3 mailboxes per domain on the standard domain setup. On plans of $1,000 or above, you can create up to 5 mailboxes per domain. Every domain and its mailboxes are managed from one dashboard.
You can buy mailboxes through Infrabox, or connect Google Workspace, Microsoft Outlook, Microsoft Azure and other or custom mailboxes. Mailbox setup and management are automated, so configuring many mailboxes does not mean doing it by hand.
Your mailbox exchanges email automatically with our warm-up network, which simulates genuine email activity and builds sender reputation. We recommend at least 2 to 3 weeks before starting large campaigns, and longer if you want a stronger start.
$3 per mailbox per month. You can use it on mailboxes you set up through Infrabox or on existing mailboxes you connect.
With Export: select the mailboxes, choose your sequencer, start the export and track its progress from the platform. You can export many mailboxes at once.
Emails sent and received, reply rate, bounce rate, email health status and overall performance for every connected mailbox, in one view, so you can spot deliverability or performance issues early.
InfraGuard monitors domain health and reputation: domain score, blacklists, DNS, bounces and IP / IPT. Email Validate checks addresses for validity, deliverability, mailbox status and catch-all before a campaign. Inbox Placement tests whether your email reaches the inbox or goes to spam.
