Enterprise & regulated
Run it inside your own walls.
SendGrid, Mailchimp, Postmark, and SES are cloud-only. For financial services, healthcare, and government, that's a hard stop. Plink runs where your data has to stay — your region, your cloud, or your own data center — with the same intelligence layer, fully managed in feel.
The gap we close
Between rolling your own and renting someone else's cloud
Until now, regulated teams had two bad options: stitch together open-source mail servers and own all the operational risk, or hand your email — content and metadata — to a cloud SaaS that can't promise it stays in your perimeter. Plink is the managed-grade platform that runs on your infrastructure, so you get the operational quality of a service with the control of running it yourself.
Deployment options
Choose how close to home it runs
Your cloud
Runs in your own cloud account for data residency, while staying as hands-off as a managed service.
On-premises
Runs in your own data center, on your hardware, under your operational controls.
Air-gapped
No outbound dependency required — for defense, government, and the strictest security environments.
Hybrid
Keep Plink's intelligence layer managed, while your own sending infrastructure and IPs stay entirely yours.
These deployment modes are in design. The chart and infrastructure modules are built and running in our own testing; none has been deployed for a customer yet. If one of these is a hard requirement for you, talk to us — we are shaping it with the first customers who need it, and their constraints decide what ships.
Compliance & control
Built for the teams with the strictest requirements
Data residency In design
Choosing exactly where your data lives — your region, your cloud, your facility — depends on the self-hosted deployment above, and ships with it.
Audit-ready logs
Every send and every agent decision is recorded with its reasoning — the audit trail reviews like SOC 2 expect. Plink is not SOC 2 certified today.
Data sovereignty In design
On private and on-premises deployments, message content and metadata stay entirely inside your perimeter — the reason those deployments exist, and shipping with them.
Dedicated IPs In design
We run our own mail infrastructure today, so your reputation is never mixed with a shared pool. Per-customer IP allocation is being specified with design partners.
White-label
Run the platform under your own brand for internal teams or downstream customers.
Who it's for
Where cloud-only isn't an option
Financial services
Email content and metadata that may not leave a defined compliance perimeter.
Healthcare
Appointment reminders, billing notices and service updates. Not for protected health information — we cannot sign a BAA yet.
Government & defense
Air-gapped and sovereign environments where nothing reaches the public internet.
Global enterprise
Data-residency mandates across regions, from EU privacy rules to APAC frameworks.
