.net - How to stop my emails to be sent as bulk email? -

I have a reason to do this

I have entered a voice message, with the email Attached, and sent it to many companies. A company, he takes voice message / email, and sends it to millions.

I want to turn off my email / voice recording again.

I am developing C #, one of my customers asked me this question. I asked them to present the verification code so that no one was able to hear the voice, but still emails would be sent to millions.

Any remedy for this problem?

Host your audio file on the website, then provide a link to that audio file in your email. Types All your emails are lightweight and they do not stop people's inbox.
