About this guide

MailBridge brings connected mailbox operations into a Velaxe workspace. Link standards-based IMAP/SMTP accounts, synchronize folders and messages, work with message bodies and attachments, compose new mail, maintain durable drafts, and manage reusable templates and published versions.

Campaign operations include audiences, recipient snapshots, scheduled delivery, deterministic A/B variants, open and click tracking, unsubscribe and suppression handling, bounce processing, recipient activity, campaign reports, and analytics rollups. Verification supports instant checks, uploaded batches, cached results, and capacity-aware worker processing.

Trusted workspace applications can discover accounts, send direct or semantic messages, use templates, mint governed Bridge v2 connections, resolve Email Hub context, and react to Email.received, Email.sent, Email.bounced, and context-change events through explicit capability and resource authorization.
