Hi indiramh,

Thanks for reaching out to the Apple Support Communities.

It sounds possible that the information in the following resource might apply, from the "If your recipient doesn't receive your message" section: If iCloud Mail isn't working - Apple Support

"If your recipient still doesn't receive your message, but your message was sent without any alerts or “undelivered mail” messages, your message might be blocked or filtered by the iCloud Mail servers or the recipient's mail server. To find out, contact iCloud Support. You should also ask your recipient to contact their email administrator."

Based on this, we'd recommend that you get in touch with your email administrator. If using iCloud, you can use this link to Contact Apple Support as well.

Take care.
