Welcome to the Explorers Hub, I hope you are well.
Hum this is frustrating when you arent getting your emails for alerts. I have gone ahead and confirmed you are not on a suppression list, which can happen if an email bounces.
Many messages can end up in you or your company’s spam filter. To ensure your system recognizes emails sent by us, add email@example.com and *@mailer-d.newrelic.com to your allow list or “Safe Senders” list as a trusted email source. Also checking your spam inbox can be a good bet.
We also have this great doc for trying other solutions for solving this issue, please see Missing alert notifications | New Relic Documentation
Please do reach out if this provided helpful, or consider making the solution option. If neither provided help to resolve the issue, please reach out and provide a link to an alert that should reporting via email.
