I am sending a very straightforward email using Send grid in my node js project. But I get returned a 403 Forbidden error. The API Key has full access. The code is also correctly integrated, as I used another API Key from another account and it works perfectly.
Error log:
Any suggestions?

Resolve a 403 error: User rate limit exceeded To fix this error, try to optimize your application code to make fewer requests or retry requests. For information on retrying requests, refer to Retry failed requests to resolve errors. For additional information on Gmail limits, refer to Usage limits.
The HTTP 403 Forbidden response status code indicates that the server understands the request but refuses to authorize it.
The error exists as the email address in the "from" field in the message(in your nodejs code,, to be sent using sendgrid) is not verified by sendgrid. Only put that email address in the "from" field which is explicitely verified by sendgrid.
To verify your sender email address to be able to send emails, refer to the link below:-
https://sendgrid.com/docs/ui/sending-email/sender-verification
Hope this helps.
(There could be further issues regarding domain name, read the link properly, they have a warning regarding use of gmail.com addresses, you can ignore that)
