Can I send transactional email from my own infrastructure?
Yes. Create a node in the console, run the Postfix-based node on your server, VM or cluster with the registration token, and it polls the console for its configuration, signs messages with DKIM and delivers them from your own IPs. Mail your applications submit to the node over SMTP never touches our infrastructure; the node ships only its delivery log lines back to the console so each message shows its timeline. Messages you submit through the REST API pass through the console on their way to your node.
Node mode is set per organisation. In self-hosted mode the shared fleet is never used: if all your nodes are down, messages retry and fail rather than leave through infrastructure you did not choose.
Two ways to send
Same console, same API. You choose where the mail leaves from.
A node on your own infrastructure
Create the node in the console, run it with the one-time token, and every message is submitted to it over STARTTLS and delivered from your IPs. If all your nodes are down, messages retry and fail rather than silently leaving through shared infrastructure.
| Property | Your own node |
|---|---|
| Runs on | Your server, VM or cluster |
| Sending IPs | Yours — your reputation, your ranges |
| Routing | Your own healthy nodes, round-robin; never the shared fleet |
| Registration | One-time node token from the console |
| Health | Node polls for config; healthy if seen in the last 10 minutes |
| Best for | Regulated data, existing mail infrastructure |
Available models
Two ways to run it, both available today
Both models include the full console: organisations, domains, senders, TLS policies, API keys and the Messages log. Pricing is agreed during onboarding.
Shared nodes
Send today through nodes we run in the European Union.
- Shared EU nodes with managed, warmed IPs

- Messages log with per-node status
- Nothing to install
Own node
Run the sending node on your own infrastructure.
- Your IPs, your queue, your logs
- Registered with a one-time token
- Signed releases, you choose the update window
- No message content processed by us
Node mode is set per organisation and can be changed later without touching your integration.
