@Rakeshsupport Are you saying that you are not able to get Zoom emails?  The message is indicating that there is a spam filter rule blocking it.  Are you on a corporate network or VPN?

In doing a little research on this, it appears that the person you are sending it to has turned on DMARC, and that restricts sending them emails from free domains such as Gmail.
