Pasting a bare URL into an email used to produce an ugly blue string of characters that told the recipient nothing about where it led. In iOS 16, the Mail app can turn that link into a rich preview card — complete with the page’s headline, image, and site name — so your messages look far more polished. The best part is that there’s no hidden setting to hunt down. Here’s how link previews work and how to make sure they appear.
How link previews work in the iOS 16 Mail app
When you paste a web address into the body of an email in iOS 16, Mail automatically converts it into a rich link: a neat card showing the destination page’s image, headline, and website name. It happens per link, right as you compose — and importantly, there is no master switch in Settings that turns the feature on or off, so don’t go looking for one. If you’d like to explore more of what Mail can do, Apple’s iPhone User Guide covers the app’s compose features in detail.
How to turn a plain link into a rich preview
Most of the time Mail creates the preview on its own, but if you only see a plain blue link, you can convert it manually:
- Copy the link you want to share.
- Open the Mail app and start a new message, or open a reply.
- Paste the URL into the message body. Mail will usually turn it into a rich preview card by itself.
- If Mail shows only a plain blue link, tap the link once — a small arrow appears next to it.
- Tap that arrow, then choose Show Link Preview from the menu.
- Mail converts the plain link into the rich preview card. Finish your message and send it as usual.
Keep an eye on message size
Rich links look great, but they make your message heavier, because the preview card embeds the page’s image. For that reason, iOS may offer to reduce the message size before sending. If you’re emailing over a slow connection, or to someone with a strict inbox quota, a plain link might be the kinder choice. And if Mail notifications are getting out of hand in general, our guide on muting Mail notifications for specific contacts on macOS can help you take back control.
If the preview doesn’t appear
If tapping the link reveals no arrow and no “Show Link Preview” option, the page you’re linking to probably doesn’t publish the metadata Mail needs — some sites don’t provide preview images or titles, and there’s nothing Mail can do about that. Try a different URL to confirm the feature itself works. Also double-check that you’re running iOS 16 or later, since rich links in Mail arrived with that release. If the option appears intermittently, force-quit Mail (swipe it away in the app switcher) and reopen it; that clears most one-off glitches. And remember: there is deliberately no Settings toggle for this feature, so don’t waste time digging through Settings — anyone describing a toggle is talking about something else.

Frequently asked questions
Can I switch a preview back to a plain link?
Yes. Tap the preview card, tap the small arrow, and choose the plain-link option to convert it back to a simple URL before you send.
Will the preview look the same on my Mac?
The preview is part of the message itself, so it renders the same wherever the email is opened. If you read mail on multiple Apple devices, our guide on setting up message sync between iPhone and Mac keeps everything consistent.
Conclusion
Rich link previews are one of those small iOS 16 touches that make everyday emailing feel more modern. Paste a URL, tap the link, choose Show Link Preview — and a plain address becomes a proper card with an image and headline. No settings to configure, no extra apps required.
