Hey @dhilipan ,
you could create a custom detection rule in M365 Defender for this and add a notification rule. The control for the notification rule is not too granular, unfortunately. In case you need more granularity for notification you would need to use e.g. Sentinel. 
The query would be the following:

EmailEvents
| where EmailAction == "Send to quarantine" and SenderFromAddress == "YOUR SENDER"
