Scenario is that i have thousands of email which i want to send email With the help of this ( i am using asp.net with C#) https://sendgrid.com/docs/Integrate/Code_Examples/csharp.html i can iterate all the emails and send emails to them (body of HTML is same and recipients are different) but this is taking too much time.
Things i done i have tried to add multiple recipent in "To" and send but this shows all the emails to every one i have tired to add multiple recipents in BCC and it shows undiscolsed
i have read that SendGrid manage this that it take values from To and send it one by one
