Enterprise assurance
For organisations that need SAML, a support SLA, and compliance tooling — regardless of size. Flat per-tenant pricing from $499 USD/month, never per seat, custom above.
Support SLA — first-response targets
| Severity | Example | First response |
|---|---|---|
| P1 — Critical | Production mail flow down, no workaround | 4 business hours |
| P2 — High | Major feature degraded | 8 business hours |
| P3 — Normal | Minor issue, workaround exists | 2 business days |
| P4 — Low | Question or cosmetic | 3 business days |
Business hours are 9am–5pm AEST, Monday–Friday, excluding Australian public holidays. These are first-response targets, not resolution times. Coverage is for the Vectis Mail software and excludes customer infrastructure, networks, DNS and deliverability, third-party components, and modified or unsupported versions. 24/7 priority response is available as a custom add-on — talk to us. We also commit to issuing critical security patches promptly and prioritising confirmed critical fixes into the next patch release.
Deliverability, honestly
Vectis Mail is self-hosted, so inbox placement ultimately rides on your own server’s IP reputation — which we equip and advise on, but do not own. We don’t sell “guaranteed deliverability”. What we provide: correct DKIM/SPF/DMARC out of the box, the dual-send warmup migration playbook (keep your current provider live while your new IP warms), and RBL monitoring today — with reputation/blocklist alerting on the Enterprise roadmap. For the same reason, we do not offer an uptime SLA: your server’s availability is yours to run.
Frequently Asked Questions
Why per tenant and not per email?
Because metered sending punishes growth. SendGrid, Postmark, Resend, and SES all price per email past a base bucket, so your bill rises with your send volume. Vectis Mail never charges per email — Pro is a flat $39 USD per tenant per month for unlimited volume, the same price whether you send 10,000 or 10 million. A tenant is your organisation, and one subscription covers unlimited Vectis Mail installs you operate.
Do I need a license to use Vectis Mail?
The Starter tier is free forever with no license required. Pro is licensed and billed through ValidonX, the default licensing backend (operated by Veltara Works) — though the endpoint Pro checks is configurable, not a hardwired dependency.
What happens if my Pro license expires?
Your mail server keeps running and all core mail delivery (Postfix, Dovecot) continues working. If a payment fails, Pro features keep working through a 21-day grace window while we retry; after that, Pro features (analytics, advanced spam controls, OIDC SSO, unlimited domains and mailboxes) revert to Starter limits but your data is never locked.
What does the Enterprise plan include?
Enterprise is for organisations that need assurance, regardless of size: everything in Pro plus SAML 2.0 SSO, a business-hours support SLA, and GDPR compliance tooling (DSAR export & erasure, data-retention controls). It’s flat-priced from $499 USD per tenant per month — never per seat — with custom pricing for larger organisations. Deliverability monitoring and SCIM are on the roadmap. Tell us what you need and we’ll size it with you.
What does the Enterprise support SLA cover?
First-response targets by severity during business hours (9am–5pm AEST, Mon–Fri, excl. AU public holidays): P1 4 business hours, P2 8 business hours, P3 2 business days, P4 3 business days. These are first-response targets, not resolution times, and cover the Vectis Mail software — not your infrastructure, DNS/deliverability, third-party components, or modified versions. 24/7 priority response is a custom add-on. Because Vectis Mail is self-hosted, we don’t offer an uptime SLA — your server’s availability is yours to run.
Can I self-host without any external dependencies?
Yes — and your mail is never coupled to a licensing service. Starter runs fully offline with no licensing backend at all. For Pro, the licensing backend is a configurable endpoint (ValidonX is the default we operate, not a hardwired dependency): it exchanges only an opaque tenant identifier and your entitlement flags — no mailboxes, message content, or recipient addresses ever pass through it. Core mail delivery (Postfix, Dovecot) never depends on it, and Pro entitlements are cached in your Postgres so they keep working offline through your current paid period if the backend is unreachable.
Am I locked into ValidonX?
No. The licensing backend is a URL you set, and Pro entitlement checks speak a documented HTTP contract — so the licensing layer isn't hardwired to one provider. ValidonX (operated by Veltara Works) is the default and what Pro is billed through; it's a convenience, not a chain. Combined with the source-available BSL 1.1 licence (which converts to Apache 2.0 four years after each release), there's no lock-in: your data lives in your Postgres, your mail runs on your server, and you can read, audit, or fork the code.
What server do I need?
Minimum: 2 vCPU, 4 GB RAM, 40 GB SSD, Ubuntu 22.04+. Recommended for production: 4 vCPU, 8 GB RAM, 100 GB SSD. Any VPS provider works.
Can I resell Vectis Mail as a hosted service?
No. Vectis Mail is licensed under the Business Source License 1.1. You may run it for your own organisation and your own end users — including operating mail for customers of your organisation. You may not offer Vectis Mail itself to third parties on a hosted, embedded, or managed-service basis in a way that competes with Veltara Works's paid version(s). For resale or hosted-platform licensing arrangements, contact licensing@veltaraworks.com.
When does Vectis Mail become Apache 2.0?
Each version of Vectis Mail converts to Apache License 2.0 four years after that version's first public release — not a single repo-wide flip. For example, v0.1.0-beta1 (released 2026-04-25) converts on 2030-04-25; v0.1.12 (released 2026-05-10) converts on 2030-05-10. Source is available throughout, and once a version reaches its Change Date, anyone can fork, host, or relicense that specific version under Apache 2.0.
