MailBridge workflow demo — connect source, connect destination, secure transfer

Connect source → Connect destination → Secure transfer. That's it.

Three steps. Full migration.

Connect, configure, and let MailBridge handle the rest — securely and reliably in the background.

1

Connect your accounts

Authenticate your source and destination email providers using secure OAuth. MailBridge never sees your password.

2

Configure your migration

Select what to migrate — date ranges, folders, labels. MailBridge plans the work and breaks it into manageable chunks.

3

Let it run

Background workers process your migration reliably. If something fails, it retries automatically. You get notified when it's done.

Built for reliability

Every design decision in MailBridge optimizes for dependable, repeatable email migration.

⚡

API-first architecture

Uses native Gmail API and Microsoft Graph — not fragile IMAP connections. Faster, more reliable, and fully authenticated.

🔄

Idempotent by design

Re-runs are safe. Duplicate messages are prevented through stable message identifiers. Interrupted jobs resume cleanly.

📦

Chunked processing

Large mailboxes are split into manageable chunks with checkpoints. No single failure can derail your entire migration.

📧

Completion notifications

Get an email when your migration finishes — with a link to the full details. No need to babysit the dashboard.

Your data, protected

MailBridge is built around the principle that your email content belongs to you — we facilitate the move, nothing more.

🔐

Encrypted tokens

OAuth tokens are encrypted at rest. We never store your email password — authentication happens entirely through provider OAuth flows.

🚫

Pass-through only

Email content passes through MailBridge during migration and is never stored in our database. Only job metadata and progress are retained.

🛡️

Minimal scopes

We request only the permissions needed for migration — read on source, write on destination. No access to contacts, calendar, or drive.
