I recently tried to email a coworker from one of my past internships, but the email bounced because the person no longer works at that company. It’s frustrating to go through the process of writing an email only to receive an undeliverable message. To solve this, I built an email validator extension using PixieBrix to help avoid this issue in the future.
Using this extension is easy. You just right-click on any email address to call the MailboxValidator API. The extension lets you know in a pop up window whether or not the email address you highlighted is valid.
You can try the extension yourself by installing from the PixieBrix Marketplace: Validate Email Addresses
Let me know if you have any questions!
