Mailboundry is Outboundry's built-in email infrastructure that lets you purchase domains, create cold email mailboxes, and launch outreach-ready sending infrastructure directly from within Outboundry.
Unlike traditional email providers where multiple customers share the same sending IPs, every Mailboundry mailbox comes with its own dedicated IP address, giving you greater control over your sender reputation and email deliverability.
Mailboundry also automates the technical setup required for cold outreach, including DNS authentication, mailbox creation, warmup, and ongoing deliverability monitoring.
Most cold outreach infrastructure relies on shared sending IPs.
When multiple senders use the same IP address, the reputation of every mailbox depends on the behavior of everyone else using that IP. If another sender starts sending spam or gets blacklisted, your mailbox reputation can also be affected.
Mailboundry eliminates this problem by assigning a dedicated IP to every mailbox, so your sender reputation is independent of other users.
Every Mailboundry purchase includes everything required to start cold email outreach.
Dedicated IP for every mailbox
Domain purchase inside Outboundry
Automatic DNS configuration
SPF configuration
DKIM configuration
DMARC configuration
Mailbox generation
Automatic email warmup
Continuous deliverability monitoring
Everything is managed directly from your Outboundry workspace.
Each mailbox receives its own dedicated sending IP.
Unlike shared infrastructure, your mailbox reputation is affected only by your own sending behavior.
Purchase outreach domains directly from Outboundry without leaving the platform.
No third-party registrar or manual configuration is required.
Mailboundry automatically configures the required authentication records for your domain, including:
SPF
DKIM
DMARC
This removes the need to manually edit DNS records.
Instead of manually creating users one by one, Mailboundry automatically generates your mailboxes after setup.
Simply provide the required information and Mailboundry provisions the mailboxes for you.
New mailboxes automatically begin warming up once they're created.
Warmup gradually builds sender reputation before and during your outreach campaigns.
Mailboundry continuously monitors your email infrastructure.
It checks:
SPF
DKIM
DMARC
MX Records
Reverse DNS (rDNS)
Sending IP blacklist status
This helps you quickly identify deliverability issues before they affect your campaigns.

Mailboundry starts at $2 per mailbox per month.
Traditional Google Workspace or Microsoft 365 mailboxes typically cost around $4 per mailbox per month, while still using shared sending infrastructure. Mailboundry offers dedicated IPs at approximately half that cost.
Dedicated IPs isolate your sender reputation from other users. Problems caused by another sender won't impact your mailbox.
