Send email via MATLAB

hello good I have problems receiving mail from thingspeak, 
I receive data from a temp sensor and I have configured a reaction for when it exceeds 28 degrees send an email and it does not arrive


alert_body = 'SENSOR DE TEMPERATURA ISSCHILE';

alert_subject = 'Temperatura Elevada';
alert_api_key = 'TAK************';
alert_url= "https://api.thingspeak.com/alerts/send";
jsonmessage = sprintf(['{"subject": "%s", "body": "%s"}'], alert_subject,alert_body);
options = weboptions("HeaderFields", {'Thingspeak-Alerts-API-Key', alert_api_key; 'Content-Type','application/json'});
%result = webwrite(alert_url, jsonmessage, options);

1. You should never share your API keys on a public platform.
2. I have noticed that you have commented out the last line of your code. Please uncomment and then try running the script. It should work just fine.

thanks, I already generated a new API code for security, the code works well but I don't get emails

I ran it and I get this error

Error using matlab.internal.webservices.HTTPConnector/copyContentToByteArray (line 396)

The server returned the status 429 with message "Too Many Requests" in response to the request to URL https://api.thingspeak.com/alerts/send.

Error in readContentFromWebService (line 46)

byteArray = copyContentToByteArray(connection);

Error in webwrite (line 139)

Error in Sensor TEMP (line 10)

result = webwrite(alert_url, jsonmessage, options);

You are making your thingspeak requests too quickly. Bulk requests should not be any less than 15 seconds apart, and if your bulk request is large then you might have to wait extra time.

Check out this answer for reference...

This looks similar to your issue.

Is the email is being sent from a loop? Try using pause() function to produce delay in between the requests.

The error message explicitly points to the problem "The server returned the status 429 with message "Too Many Requests" in response to the request to URL https://api.thingspeak.com/alerts/send." Please refer to the documentation of the API.
