Cold email mailboxes built
for optimum deliverability
Provision, monitor, and scale cold email infrastructure.
Mailboxes starting at $1/month
Trusted by cold email operators, agencies, and high-volume outbound teams managing hundreds to thousands of inboxes
Cold email doesn't break because of copy
It breaks because of infrastructure
Outbound teams fail when infrastructure becomes fragile, manual, and invisible.
Most teams rely on spreadsheets and disconnected tools to:
-
Purchase and manage domains
-
Configure DNS authentication correctly
-
Create and rotate mailboxes in bulk
-
Monitor deliverability and reputation
-
Replace infrastructure before it fails
Most tools sell mailboxes
