How to Turn Mail’s Rich Website Previews into Plain Links
Sometimes apps can be too helpful. Apple’s Mail on the Mac likes to turn pasted URLs into graphically rich previews, and sometimes that’s OK. But other times, the preview is confusing or takes up too much space. Or you may want to send a plain link so the recipient can see its text. There are three ways to avoid rich link previews:
Before pasting a URL into your message, type a space or any other text. Mail converts URLs to rich previews only when they’re on a line by themselves.
Hover over the preview, click the down-pointing arrow that appears, and choose Convert to Plain Link from the pop-up menu.
In Mail > Settings > Composing, change the Message Format pop-up menu to Plain Text. Although this eliminates rich link previews, it also prevents you from including formatting and images.
