Hey @pawan 

From what I know, the only reliable way to block events from being ingested is by specifying the IP address in the Data Filter. We can completely block the event being ingested or the event/user properties itself. But I haven’t seen any block filters available based on the value of a particular property ( which is email id in your case).

Either you make some changes in your instrumentation to stop these users from sending these events or you can submit these user IDs to the Amplitude support team for blocking on their backend.

Hope this helps.

@Saish Redkar thanks how do i contact with amplitude I mean their can you send here contact email

I think the direct support email depends on your plan type. Tagging @Jeremie Gluckman for support visibility and additional help.

Thanks for looping me in @Saish Redkar. You’re the best! 

@pawan You can submit a request to the team here. Please keep us posted here as you make progress.
