Every email account you deploy is routed through pre-warmed IP blocks, completely isolated from other users' traffic, carrying excellent sender scores.
Connect your domains and create email accounts. SPF, DKIM, DMARC, and PTR records align automatically to guarantee immediate compliance.
Manage responses across all pre-warmed accounts from a single unified dashboard. No more logging into hundreds of workspaces separately.
It's an inbox associated with a sending domain that has already established a positive sender reputation with major mailbox providers (Gmail, Outlook) through gradual, low-volume communication, avoiding immediate spam filters.
We route outgoing mails through our own established, pre-aged infrastructure IPs. While new domains still require a short ramp to align domain trust, your IP-level sending reputation is already established, enabling you to scale much faster than traditional setups.
