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.
It's the same product in every mode. On private and on-premises deployments, your email content never leaves your network — and updates roll out on your schedule, with your approval.
Compliance & control
Built for the teams with the strictest requirements
Data residency
Decide exactly where your data lives — your region, your cloud, your facility. Nothing crosses a boundary you didn't set.
HIPAA BAA
A Business Associate Agreement is available for healthcare workloads that touch protected health information.
Audit-ready logs
Every send and every agent decision is recorded with its reasoning — the audit trail reviews like SOC 2 expect.
Data sovereignty
On private and on-prem deployments, message content and metadata stay entirely inside your perimeter.
Dedicated IPs & SLA
Your own sending IPs and a custom service-level agreement matched to your volume and risk profile.
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
Patient communications and notifications that involve protected health information.
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.
