Official Infrastructure
Google or Microsoft — Your Choice

Both are official, US-hosted, and configured to the same exacting standard. Pick the platform your team knows best.

Google Workspace

Gmail Infrastructure for Cold Outreach

Official Google Workspace inboxes hosted in the US. Gmail’s reputation means higher primary inbox placement, especially when SPF, DKIM, and DMARC are configured correctly — which we handle entirely.

Microsoft 365

Outlook Infrastructure for Cold Outreach

Official Microsoft 365 mailboxes — not shared SMTP servers. Microsoft’s deliverability infrastructure combined with our DNS configuration delivers consistent primary inbox placement across B2B outreach at scale.

The Process
From sign-up to sending
in five steps

No back-and-forth, no technical drag. We own the entire setup from domain to first send.

01
Domain Registration & Configuration
▼
We register clean, dedicated sending domains completely separate from your primary business domain. This protects your main brand if deliverability issues ever arise, and gives us full DNS control from day one.
Already have a domain? No problem — you can provide your own domain and we’ll configure everything on it. We’ll handle all DNS records, authentication, and setup on your existing domain at no extra charge.
Dedicated Sending Domains Brand Protection Bring Your Own Domain Clean Domain History
