Import Email
You can migrate your existing email history into SipherMail from Gmail, Outlook/Microsoft 365, Yahoo, or any IMAP provider.
Supported import sources
- Gmail — OAuth import (no password required, secure scope-limited access)
- Outlook / Microsoft 365 — OAuth import
- Any IMAP provider — Enter IMAP host, port, username, and app password
How to start an import
- Go to Settings → Import & Migration.
- Select your source (Gmail, Outlook, or Custom IMAP).
- For Gmail/Outlook: you'll be redirected to the provider's OAuth consent screen. Grant the read mail scope only — SipherMail never requests write access to your old mailbox.
- For custom IMAP: enter your server details. Use an App Password if your provider supports 2FA (Gmail, Yahoo, Outlook all require this).
- Select which folders to import (Inbox, Sent, All Mail, or specific labels).
- Click Start Import. You'll receive a push notification and email when the import completes.
Import progress
Imports run in the background. You can continue using SipherMail while the import runs. Check Settings → Import & Migration → Import History for progress and any errors. Large mailboxes (10k+ emails) may take 15–30 minutes.
After import
Imported emails appear in a folder matching their original label/folder. They are immediately searchable and available offline (mobile). Attachments are available for preview and download.
Notes & limits
- Import is a one-time copy — ongoing sync is not available in this version.
- OAuth refresh tokens are stored encrypted. You can revoke access at any time in Settings → Connected Accounts.
- Import quota counts against your plan storage.
