Hi,
First of all I would like to thank @alex_melkoff for providing this app for sendgrid integration. I have tried to install this app but it seems that the app is not communicating with sendgrid.
My email account is properly setup since I am able to send emails from my account via sendgrid but the problem is that the status of the emails is not getting updated.
I have created a API key and entered the same in the API key in email account but what I think is the problem is that the email notifications setting in the Sendgrid Account is INACTIVE.
Is there a way I can debug what exactly is going wrong and then try to make this integration work.
