Beginning with macOS Ventura, Apple’s Mail app adds a rich link preview when you’re composing an email and paste a web address into the email window. For example, here’s how it looks when I paste the following URL into a new email:

https://wwww.apple.com

For those who find this behavior undesirable and wish to turn it off, it can be disabled using the following process:

1. Launch Mail

2. Under the Mail menu, select Settings.

3. In the Settings window, select the Composing option.

4. Uncheck the Add link previews option.

With this option disabled, here’s how it looks when I paste the following URL into a new email:

https://wwww.apple.com

I have not found a way to disable the Add link previews option in Apple’s Mail app on macOS Sequoia using a defaults command, but it is possible to disable the Add link previews option using a configuration profile. For more details, please see below the jump.

The relevant preference domain and key values are below:

• Preference domain: com.apple.mail
• Key: AddLinkPreviews
• Value: Boolean

Setting a boolean value of false will disable the Add link previews option in Apple’s Mail app on macOS Sequoia. I’ve built a configuration profile with the boolean value of false set, where the profile is available on GitHub via the link below:
