>_ Nexoxa Bridge — SMTP & mail
SMTP mail studio for developers
Mail testing in your infra workbench
Mail studio is NexoxaBridge's integrated SMTP workbench. Save smtp:// connections in the encrypted vault, verify TLS, compose messages, and send tests — same app as PostgreSQL, SSH, and SFTP.
Free for up to 5 connections · Windows desktop
Your data stays yours
Local-first by default. Read how Bridge handles secrets.
100% local vault
Connection URLs, SSH keys, and SMTP secrets stay encrypted on your Windows machine — not in a Nexoxa cloud vault.
Zero vault telemetry
We don’t ship your credentials or query results to our servers. Account and billing stay separate from your connection vault.
Direct connection
Bridge talks straight to your databases, SSH hosts, and storage endpoints. No proxy that holds your passwords.
