You'll access the ESP settings from the project settings in the top right-hand corner of CloseAlert:
After you enter the ESP settings and have selected your ESP, you have the option to dis-/ or enable the HTTP(S) connection under 'Step 2: ESP settings'
Enable or disable HTTPS
For security reasons, HTTPS is enabled by default. Since you are likely to include personal identifiable information (PII) in the URL, we advise to send your emails over HTTPS from your ESP, at all times.
Though we don't recommend it, you can use the toggle to disable HTTPS and run the feedback over a non-secure HTTP URL.
