Follow these 5 simple steps to add Email Alerts to OnDOMAIN:
Go to Settings.
Scroll down to Email Alerts.
Enter your email addresses (No limitation on the number).
When OnDOMAIN uncovers lookalikes, an email will be sent with the information to the email addresses listed in the corresponding settings section (and to Splunk/Demisto/Slack, if configured).
Email addresses are entered in the settings box one by one, separating them with commas. Repeat this until you've added all the necessary emails addresses you need.
