Self-hosted: the Kavik engine on your infrastructure
Everything the cloud API does, running in your own Docker environment: the full 28-check engine, the dashboard, bulk processing, and the REST API. Your lists never leave your network, and there is no per-email cost.
Who it is for
- Teams whose lists cannot leave their infrastructure, for policy or contract.
- High-volume senders for whom per-1,000 pricing stops making sense.
- Product teams that want verification inside their own stack, behind their own firewall.

What you need
A Docker host (or a small cluster, for very large lists), outbound port 25 from your IPs or proxies, and about ten minutes. The compose file brings up the API, dashboard, database and worker with health checks, mirroring the cloud deployment you can inspect at our status page.
How to buy
Payment is crypto through our self-hosted checkout, as with the cloud plans. Write to support@verifications.email with your company details and we will issue the license and images the same day. If you want to evaluate the engine first, the cloud free tier runs the identical checks.
