Having a healthy and well-performing website is important, both to you as the webmaster and to your users. When we discover critical issues with a website, Webmaster Tools will now let you know by automatically sending an email with more information.
We'll only notify you about issues that we think have significant impact on your site's health or search performance and which have clear actions that you can take to address the issue. For example, we'll email you if we detect malware on your site or see a significant increase in errors while crawling your site.
For most sites these kinds of issues will occur rarely. If your site does happen to have an issue, we cap the number of emails we send over a certain period of time to avoid flooding your inbox. If you don't want to receive any email from Webmaster Tools you can change your email delivery preferences.
We hope that you find this change a useful way to stay up-to-date on critical and important issues regarding your site's health. If you have any questions, please let us know via our Webmaster Help Forum.
