Error email on 204 response

Thanks for this plugin, it’s just what I need to send data to a custom webhook script!

I’m running into an issue where the webhook script sometimes returns a 200, but othertimes a 204, just depending on whether or not there is content to return. It looks like this plugin only checks for 200 responses. Could it be changed to check for any 2XX response as a valid response, and maybe even 3XX responses too?

Thanks!
