The simplest way to include a link in an email message is to copy and paste it. You can then copy the link from the message and paste it into the browser. However, if you’d rather include a hyperlink that takes the user directly to the page by clicking on the text, follow these steps:

Alternatively, you can paste an entire link (including http:// or https://) directly into a Yahoo Mail message. Depending on how the web page is set up, the pasted text is hyperlinked automatically, or a link preview is generated with an image. To adjust the size and positioning of the link preview, hover the mouse pointer over the preview image, then and select the ellipses (…) in the upper-right corner.

Yahoo Mail Basic doesn’t support link previews, but it is possible to include hyperlinks: When the recipient sees the message, they can click the underlined text to open the web page in a new tab.
