Email alerts quickly inform you of security related events on your site.
Wordfence monitors activity on your site, both via the scanner and the firewall. Alerts are sent out via email. The recipient email of these alerts is configured when Wordfence is installed and can be changed under the “General Wordfence Options” section on the “Dashboard” > “Global Options” page.
The Wordfence alert function uses the built-in WordPress email function, which in turn uses the PHP mail function on your server. If you are using an SMTP plugin that overrides the WordPress built-in email function then that will be used for sending the alerts instead.
Wordfence can alert you when someone is locked out from login, when users sign in to your site, or when there is a large increase in attacks. You can configure these alerts under the “Email Alert Preferences” section.
When configuring scan alerts, you can choose the lowest severity of alerts that you would like to be notified of. Wordfence will send an alert for each new issue of that severity or higher that is found in automatic scheduled scans, unless you have disabled email alerts from individual sites in Wordfence Central. You can find more information about scan results here.

If you are no longer receiving Wordfence emails from your site, a common reason is that your email server’s IP address has been added to a blocklist, and your WordPress site emails won’t be received by many other people, including you.
You can look up your site’s domain or IP address, to see whether it’s on a third-party blocklist/blacklist at this URL:
Enter your WordPress site’s IP address or domain, and if you see it listed on an email blocklist, contact your hosting provider for further instructions.
If your site is not on a blocklist, you can also use the “Send a test email from this WordPress server to an email address” option at the bottom of the Diagnostics page on the Wordfence Tools menu, to test if a simple message will be delivered. If that test message is not delivered, your host may need to investigate the issue.
