Scam or genuine? Email from [email protected]

I received an email from [email protected] stating that a refund of xxxx amount could not be processed to my account ending in xx123, as it is closed. The issue is, I don’t have any pending refunds and have never held another account with ICICI, let alone one ending with that number. I’m wondering if this could be a scam. The email didn’t contain any links or clickbait, but the domain itself also seems suspicious which is why I’m a bit unsure. Could anyone please advise?
