@SushantKadam008 Each email address in the personalization block should be unique between to, cc, and bcc. sushantkadam17@gmail.com is repeated between to and bcc.

@SushantKadam008,

@paritoshmmmec is correct, this is expected behavior.

Thanks!

I tested it and it works with different email address. But in this atleast proper exception needs to be raised as Bad Request does not tell clearly that To and Bcc are same. We might get Bad Request in mutliple scenarios

Hi @SushantKadam008,

You should be able to retrieve the exception message like so: https://github.com/sendgrid/sendgrid-csharp/blob/master/TROUBLESHOOTING.md#error

Please let me know if that does not fit your needs.

Thanks!
