Please ensure you are using a different email to get alerts in addition to your company email. I have seen DNS outages completely take a company off the face of the Internet. In these scenarios, mail flow is interrupted so you want to be getting critical alerts to a personal email address, via SMS, and/or push notification on your phone.
In-session feedback is my favorite way to capture user feedback. Just emailing a simple SharePoint or SurveyMonkey poll to your users periodically will also suffice, but may not give you as many responses. 2b1af7f3a8
