About this guide

MailBridge centralizes business email inside your Velaxe workspace. Connect IMAP/SMTP accounts (including OAuth providers) and the background poller ingests folders, flags, bodies, and attachments with safe throttles. Compose drafts with uploads, send immediately, or enqueue to the bulk sender with pacing and retry policies.

A hardened, timestamped HMAC bridge lets external apps request account suggestions or send mail via signed requests—no CORS headaches. Connections include scopes, IP allowlists, and rotating secrets with audit logs and analytics.

Verification tools probe domains/MX/SMTP and cache outcomes to reduce bounces. Events integrate with workflows and AI responses so teams can automate follow-ups and logging into CRM/Chronicle.
