AI WORLD HQTame Your Inbox with Apple Intelligence in Mail
A beginner-friendly walkthrough to summarise long emails and polish replies in Mail using built-in AI on iPhone, iPad and Mac.
By the end of this guide you'll be able to skim a long email in seconds and send a tidy, polite reply without typing the whole thing yourself. This is for anyone who uses Apple Mail on iPhone, iPad or Mac and wants to spend less time drowning in their inbox. Apple Intelligence is Apple's built-in AI assistant — think of it as a quiet helper that lives inside your apps and can read, write and tidy text for you.
💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.
- Device you'll need: An iPhone, iPad or Mac that supports Apple Intelligence. In practical terms, that means an iPhone 15 Pro or newer, any iPhone 16, an iPad with an M-series chip, or a Mac with Apple Silicon (M1 or later). If you're unsure, open Settings and search for "Apple Intelligence" — if the toggle appears, you're good.
- System version: Update to the latest iOS, iPadOS or macOS before you start. The Mail features below live inside that update, not in a separate app you need to download.
- iCloud sign-in: You'll want to be signed into iCloud with a small amount of free storage available. No extra subscription is required for the Mail tools covered here.
- Time: About 5 minutes to set things up, then roughly 30 seconds per email once you're practised.
- One honest limit: Apple Intelligence can summarise and rewrite, but it cannot send email for you. You always review and tap Send yourself — and you should, because the suggestions aren't perfect.
Turn Apple Intelligence on
Open the Settings app on your iPhone, iPad or Mac. Scroll down and tap Apple Intelligence & Siri (on Mac this is under Apple Intelligence in System Settings). Toggle Apple Intelligence on if it isn't already. A short download begins — you'll see a status message like "Getting Ready…" while Mail's features are prepared, and then a confirmation that Apple Intelligence is ready to use. If you can't see that toggle at all, your device may not support Apple Intelligence; double-check the supported models in "Before you start". You'll know it worked when the setting shows a green tick and a welcome message appears on screen.
Open Mail and find a long email
Open the Mail app from your home screen, Dock or Launchpad. Tap (or click) into your inbox and pick an email with more than a few paragraphs — a newsletter, a meeting recap or a long reply from a colleague works well. The full message opens with the sender's name at the top and the body of the email below. If your inbox is empty, send yourself a long block of text first, or wait for the next newsletter that lands. You'll know it worked when you can see the full email body and the standard Mail toolbar (Reply, Forward, Archive and so on) is visible.
Let Mail summarise the email automatically
With the email open, scroll to the top of the message and pause for a second. Apple Intelligence automatically generates a short summary at the top of long emails — it appears as a couple of crisp sentences above the original text, with a small "View Original Email" link beneath if you want to see the full version. There's no button you need to press; the summary simply shows up. If you don't see a summary, the email may be too short to need one, or the feature may still be rolling out on your device — in that case, swipe down from the top of the email to refresh. On some devices you'll also see a brief summary directly under the email in your inbox list, before you even open it. You'll know it worked when a short, plain-English summary appears above the original text and the rest of the email sits neatly underneath.
Open Writing Tools inside your reply
Tap Reply as you normally would (the curved arrow at the top or bottom of the email). A new compose window opens with the original message quoted below. Place your cursor inside the empty reply area, then look for the Writing Tools option — on iPhone and iPad it's usually found by tapping the Aa formatting icon above the keyboard, then choosing Writing Tools; on Mac it's under Edit → Writing Tools in the menu bar. A small panel appears with options like Rewrite, Proofread, Summary, Make Friendly, Make Professional and Make Concise. If your screen looks different, look for an icon that resembles a pen with sparkles, or a small ⋯ menu inside the compose window — Writing Tools sometimes hides there. You'll know it worked when a popup or floating bar appears with at least three tone and editing options.
Tidy your reply with Rewrite, Proofread or a tone change
Start by typing a rough reply yourself — even just a few words is enough. Then choose a Writing Tool: tap Proofread to fix spelling and grammar, tap Rewrite to rephrase the whole draft, or pick a tone like Make Friendly, Make Professional or Make Concise to adjust how it sounds. Mail rewrites the text in place; the original sits underneath so you can compare. If the first rewrite isn't quite right, tap Rewrite again for a fresh take, or edit your draft first and try once more. The Summary option gives you a short version of what you've written — handy before you send a long reply.
You'll know it worked when your reply text changes on screen and you can tap to swap between the original and the new version.
Read, personalise and send the email yourself
Read the rewritten reply out loud once before sending — this is the most important step. AI suggestions aren't perfect, and you know things the AI couldn't (a colleague's nickname, an inside joke, a private detail). Add anything personal, double-check any names, dates or numbers, and make sure the tone sounds like you. When you're happy, tap Send exactly as you would for any normal email. Apple Intelligence never sends anything on your behalf — that's by design. You'll know it worked when your message lands in the Sent folder and the recipient gets a reply that sounds like you on a calm, well-rested day.
- Mistake: Trusting the summary without checking. Fix: Always glance at the original email if the summary mentions numbers, dates or money. AI summaries can occasionally drop a small but important detail.
- Mistake: Sending the rewritten reply unchanged. Fix: Read it once out loud. If it sounds stiff, robotic or oddly formal for the relationship, pick Make Friendly or Make Concise, or rewrite your draft first and try again.
- Mistake: Looking for a Summarise button on every email. Fix: Apple Intelligence only shows summaries when an email is long enough to need one. A one-line "Thanks!" message won't get a summary — and that's fine, just reply normally.
- Mistake: Assuming it works on every device. Fix: Older iPhones, iPads and Macs don't support Apple Intelligence. If the Writing Tools option is missing, check that your system is up to date and your device is on the supported list — otherwise the feature simply isn't available yet for you.
Open Mail, find the longest unread email you have, scroll up to read the auto-summary, then tap Reply → Aa → Writing Tools → Make Professional on a rough draft you typed yourself. Read it out loud, tweak it, and send it. You'll have just triaged and answered an email in under a minute.
