Yes! In your Registration Settings there is a new section called "Registration Notifications".
Use the toggle buttons on the far right to turn Email Notifications or Slack Notifications On or Off individually. If an option is turned on, you will need to choose to receive your notifications either Instantly or Daily. Instant notifications will send every time someone registers while Daily notifications send once per day, about 9 AM EST, with the number of new registrants since the previous email.
