Hello, I am developing a Smart Bin monitoring project using an ESP32, ThingSpeak, and MATLAB Analysis. I want to receive an email notification whenever the bin fill level reaches 70%. I created an Alerts API Key and used it in my MATLAB Analysis code. The code reads Field 1 from my ThingSpeak channel and sends an alert when the fill level is at least 70%. However, I have not received the email. I checked the following: The registered email address in my ThingSpeak account is correct. I checked my Inbox and Spam folder but could not find the email. The ThingSpeak Alerts History API returns the following: Subject: Smart Bin Fill Level Alert Status: sent Requested at: 2026-10-18T09:14:39.774Z Sent at: 2026-10-18T09:14:40.036Z The alert allowance also decreased by one after testing. Despite this, the email has not arrived. Could someone explain how to troubleshoot this issue and determine whether the email was actually delivered or rejected? Thank you.
