Intimation hasn't been received from IT Department through Mail regarding processing of ITR.

ITR for AY 2020-21 and PAN xxxcxxxxxx has been processed at CPC. Intimation u/s 143(1) has been sent to your registered email ID. If not received check in SPAM folder.

The above said message was from IT Department through SMS. But the said person didn't receive any mail regarding the same, anyone can please respond to my query whether the SMS is invalid as I didn't get any intimation through mail. Thanks.
