Apple Mail Tips and Tricks That Make It Bearable

Apple Mail catches flak for being plain compared to Superhuman or Spark. It also handles 100,000-message archives without choking, syncs reliably across devices, and works offline — three things most “modern” email clients fail at. The trick is configuring it right, then using the features Apple stopped advertising in 2018. Here’s how.

First: stop Mail from eating your disk

Open Mail, hit Cmd-,. Accounts tab, pick your account, Account Information. Find “Download Attachments” and change it from “All” to “Recent” or “None.”

Then Mailboxes menu, Erase Junk Mail, In All Accounts. Mailboxes menu, Erase Deleted Items, In All Accounts.

Quit Mail. Open ~/Library/Mail/ in Finder (Cmd-Shift-G, paste the path). The folder is probably 10-50 GB. After the steps above, it’ll halve.

This is the single biggest improvement most users make to Apple Mail. The default “download every attachment forever” setting is why Mail feels slow and your Mac feels full.

Smart Mailboxes (the secret weapon)

Mailbox menu, New Smart Mailbox. Smart Mailboxes are saved searches that live in your sidebar — they don’t move messages, they show you matches.

Useful Smart Mailboxes:

• Unread from this week: Date Received in last 7 days, Message is Unread
• VIP: From any of [list of important people]
• Has attachment: Contains attachment is Yes
• Receipts: Subject contains “receipt” OR “order” OR “confirmation”
• Newsletters: From contains “newsletter” OR Subject contains “unsubscribe”
• Action needed: Flagged is Yes

The “Newsletters” mailbox is gold. Once you can see every newsletter in one place, unsubscribing from the dead ones takes 5 minutes.

Rules (real automation)

Mail, Settings, Rules, Add Rule. Rules let you automate everything that happens to incoming mail. Examples:

• Auto-archive newsletters: From contains “[email protected],” Move to Newsletters folder, Mark as Read
• Flag emails from your boss: From is “boss@company.com,” Flag with Red, Set Color to Red
• Move shipping notifications: Subject contains “shipped” OR “tracking number,” Move to Receipts, Mark as Read

Order matters. Rules run top-to-bottom; the first match wins unless you tick “Stop evaluating rules” off.

The hidden bit: rules also run on existing messages. Right-click any folder, “Apply Rules” runs all your rules against that folder’s contents. Useful when you set up a new rule and want it to clean up the backlog.

Search operators

Mail’s search bar is more powerful than it looks. The operators:

• from:jane@example.com — sender
• to:me — sent directly to you
• subject:invoice — subject contains “invoice”
• attachment:pdf — has a PDF attached
• is:unread, is:flagged, is:read
• date:today, date:yesterday, date:"this week"
• Combine: from:boss subject:review date:"last month"

Click the small magnifying glass at the left of the search bar to narrow the search to a specific mailbox.

Format like a normal person, not Apple Mail

Apple Mail’s default is rich text with the system font and Apple-specific formatting that looks ugly on non-Mac clients. Switch to plain text:

Mail, Settings, Composing, “Message Format” → Plain Text.

Now your emails come through as readable text everywhere. Format only when you actually need formatting (Cmd-T toggles between rich and plain in the compose window).

Stationery is gone, good

Apple killed Mail Stationery in macOS Ventura. If you ever miss it, you don’t.

For consistent signatures: Settings, Signatures. Per-account signatures, with formatting. Tick “Always match my default message font” so the signature inherits your message’s style.

VIP

Right-click any sender, “Add to VIPs.” VIPs get a special folder and can be set up to bypass focus modes for notifications. Useful for family, your boss, your accountant.

In Settings, Notifications, set “When Receiving” → “VIPs only” so you only get pinged for senders that matter.

Quick replies

Apple Mail in Sonoma added inline reply suggestions. Tap the suggestion bubbles above the toolbar and they fill in the body. Configure tone in Settings, Composing.

For full templates, Mail doesn’t have a native templates feature — workaround: create draft messages in your Drafts folder, never send them, duplicate them to start new emails. Or use a system-wide text expander like Raycast snippets, which works in Mail.

Markup attachments inline

In any received email, hover an image attachment. The little markup icon appears. Click it, annotate the image with arrows, text, signatures, then send back as a reply. No need to download, edit, re-attach.

For PDFs: click any PDF attachment to open Quick Look preview, hit the markup icon at the top, fill in form fields and sign with your trackpad. The signed PDF replaces the original on the next send.

Send Later

Sonoma added scheduled send. Click the dropdown next to the Send button, pick a time. The email sits in Drafts until then. Useful for sending late-night emails at a reasonable hour or scheduling reminders.

Undo Send

Settings, Composing, “Undo send delay.” Default is 10 seconds. Bump it to 30. Once you hit Send, an “Undo Send” button appears at the bottom of the sidebar for 30 seconds. Click it, the email comes back.

Filtering and sorting

The toolbar above the message list has a filter button (looks like three lines). Click it to limit the current mailbox to:

• Unread only
• Flagged only
• From or to VIPs
• With attachments
• Today

Combines with Smart Mailboxes for surgical views.

Archive, don’t delete

Inbox zero on Apple Mail: Cmd-Ctrl-A archives. The keyboard shortcut works in any folder. Old messages go to All Mail (for IMAP/Gmail) or Archive (for iCloud). They’re searchable but out of sight.

If you prefer Delete: change the swipe direction in Settings, Viewing, Swipe Options.

Threading

Settings, Viewing. Set “Sort by” to “Date (Newest at Bottom)” if you want chat-style threads (newest reply at the bottom). Tick “Group messages by subject thread” so related emails collapse together.

The unfold button on a thread shows every message; the strikethrough message indicator means you’ve replied.

Mailbox keys

Once you have your folders set up, learn the move shortcuts:

• Cmd-Shift-M → “Move to Mailbox” with a search
• Or assign keyboard shortcuts to specific mailboxes via System Settings, Keyboard, Keyboard Shortcuts, App Shortcuts. Add Mail.app and set “Move to Receipts” to Cmd-Shift-1, etc.

After two days you’ll be sorting your inbox at the speed of your typing.

Performance fixes

If Mail is slow:

1. Rebuild the index: Quit Mail, delete ~/Library/Mail/V10/MailData/Envelope Index*, restart Mail. It re-indexes from your messages
2. Vacuum the database: in Terminal with Mail closed, sqlite3 ~/Library/Mail/V10/MailData/Envelope\ Index 'VACUUM;'
3. Reduce the cache: Settings, Accounts, Account Information, Download Attachments → Recent
4. Remove dead accounts: Settings, Accounts, select the account, Sign Out. Old accounts you no longer use still sync and waste space

Mail isn’t the answer for everyone

If you live in 200+ emails a day with strict triage, Superhuman or HEY are faster. For developer mailing lists, Thunderbird is more capable. For light-touch personal email plus syncing across Apple devices, Apple Mail is fine — and the configuration above gets it from “frustrating” to “actively useful.”

The trap is treating Apple Mail like Outlook 2003 with worse design. With Smart Mailboxes, rules, VIP, scheduled send, undo send, and proper attachment management, it does about 80% of what the premium clients do, with zero subscription cost and end-to-end iCloud sync built in.
