In Slack you can configure an email app. Once it is configured, you will get an email address from Slack which you can use to send emails to a specific Slack channel. Take this email address now and add it to the email list of the Foglight service.
To get further details about the email app in Slack, look at the Slack documentation or contact Slack support.
