- Set sync frequency or choose push/scheduled modes if supported.
- Enable offline caching if you need access without internet.
-
Identity & signatures

Key features and how to use them
Unified inbox
- Combine multiple account inboxes into one view. Use the account filter to focus on a single account.
Conversation view
- Toggle threaded view to group emails by conversation for easier reading.
Rules & filters
- Create rules to auto-move, label, flag, or mark messages as read based on sender, subject, or keywords.
- Use rules to automatically archive newsletters or route receipts to a “Receipts” folder.
Labels & folders
- Use labels for flexible categorization; folders for strict hierarchy.
- Color-code important labels for quick scanning.
Search and saved searches
- Powerful full-text search across all accounts; use operators (from:, to:, subject:, has:attachment).
- Save frequent searches (e.g., “in:inbox from:[email protected] has:attachment”) as quick filters.
Snooze & reminders
- Snooze messages to temporarily remove them from the inbox and have them reappear at a specified time.
- Set reminders or follow-ups on messages you need to act on later.
Templates & canned responses
- Create templates for common replies (meeting confirmations, support responses).
- Insert placeholders (name, date) and use quick keyboard shortcuts.
Encryption & security
- Supports S/MIME and PGP for end-to-end encryption (manual key setup required).
- Two-factor authentication (2FA) supported where provider supports it via OAuth.
Productivity tips
- Keyboard shortcuts: Learn core shortcuts (compose, reply, archive, search) and customize them.
- Use focused inbox + rules: Let automatic categorization surface important messages and move low-priority ones away.
- Batch processing: Set times to process email instead of reacting continually.
- Quick actions: Configure swipe gestures on mobile and message toolbar actions on desktop for archive/delete/mark-read.
- Archive, don’t delete: Keep an “archive” habit to keep the inbox clean while preserving history for search.
- Use saved searches as virtual folders for project-based workflows.
Performance & storage management
- Limit folder sync to those you actively use to reduce disk usage.
- Clear or limit attachment caching; download attachments on demand.
- Compact/mailbox maintenance: Use the built-in compact/repair functions if you notice database growth.
- For very large accounts, use server-side archiving or export old mail to local archives.
Troubleshooting
- Can’t connect to provider:
- Verify username/password.
- For Gmail/Outlook, use OAuth or app-specific passwords; ensure IMAP is enabled in account settings.
- Check server hostnames and ports (IMAP: 993 SSL, SMTP: ⁄587 TLS).
- Messages not syncing:
- Confirm sync frequency and folder selections.
- Rebuild the account index/cache from Settings > Accounts > Advanced.
- Notifications not appearing:
- Check OS notification permissions and app notification settings.
- Ensure Do Not Disturb modes aren’t blocking alerts.
- Slow performance:
- Reduce synced folders, clear cache, or increase local resources (RAM).
- Lost messages:
- Search “All Mail”/Archive; check server webmail to verify if messages are present server-side.
- Restore from local backup if you exported mail previously.
Advanced setup examples
-
Gmail (OAuth)
- Choose Gmail, follow Google OAuth screens, grant mail read/write and labels access.
- Enable IMAP in Gmail settings if prompted.
-
Exchange/Office 365
- Select Exchange/Office 365, sign in with corporate credentials, accept permissions.
- For on-premise Exchange, use EWS or IMAP depending on server configuration.
-
Manual IMAP/SMTP
- IMAP server: imap.example.com, port 993, SSL/TLS
- SMTP server: smtp.example.com, port 587, STARTTLS
- Authentication: username as full email address; use app password if 2FA enabled.
Backup & migration
- Export mailboxes to standard formats (MBOX or EML) for backups.
- Import from other clients (MBOX/EML/Outlook PST) via Import/Export tool.
- For account migration, add both old and new accounts and copy messages/folders between them.
Final checklist before daily use
- Add all accounts and confirm sync.
- Create 3–5 rules to auto-sort incoming mail.
- Build a couple of templates for frequent replies.
- Set notification preferences and keyboard shortcuts.
