ok. Starting to understand your position now.
You are on a 1 year extension of stay based on visiting family ( wife or half Thai child).
As
@Chris ******
mentioned, if immigration decide to cancel your extension, it won't be via an e-mail.
Maybe post a redacted image of the email and email address.
Also, on some email providers, there's a small drop down arrow > that will show the full email address
