Stop renting your outbound. Own your stack.
Send cold email from your own Microsoft 365 mailbox that actually lands in the inbox — without burning your domain. We verify SPF/DKIM/DMARC, write each email with AI, stop the moment someone replies, and keep a suppression list you can defend. Complimentary for vetted members.
Built for Microsoft 365 mailboxes. Bring your own domain + inbox, or have us set it up.

Measured automatically: created → fix deployed. Customer-side confirmation delay is excluded.
Open to apply, vetted to join
Anyone can apply. Every member is vetted for deliverability discipline before they send — that's how the network stays clean. Bring your own domain + mailbox, or have us set it up.
Built for deliverability
Send from your own Microsoft 365 mailbox, SPF/DKIM/DMARC verification, send-window controls, auto-stop on reply / bounce / unsubscribe, and a permanent "do not contact" list scoped to your account.
Support that's measured
File a ticket → we approve, fix, deploy → you test and confirm. Every step timestamped. The number above is real, not a marketing claim. See the resources.
