In the next lecture, we will be adding a number of configuration properties to the Mailer. Due to a major Sendgrid update, we will no longer be able to use no-reply@emaily.com
When we write out this line:
this.from_email = new helper.Email('no-reply@emaily.com');We instead need to use the email address of the "Sender" that we configured in the new setup notes:
You will not be able to use the API if you have not created and verified the Sender and generated an API key for that Sender.
