Our Chrome extension, "Hold Your Horses," is designed to warn you if there are any third-party domains in your recipients. This will save you from embarrassment and potentially worse scenarios.

You can also add email domains to an ignore list. For example, if your domain is kapitalone.com and you email frequently to clients or suppliers, you can add their domains to your ignore list and still be able to send them an email but you won't have to worry about them getting annoyed and emailing you back.

Avoid sending incorrect emails and keep your correspondence safe and secure with this extension.
