Email looks legit (from "noreply @ zohoaccounts.com") Link in email also looks legit (goes out to accounts.zoho.com)

But when I go to my zoho accounts page, there are no sessions or activity that corresponds to the time specified in the alert.  Nor is there activity shown in the geography specified in the email.

I think everything is fine, but would like to understand why I got the email.  Any thoughts would be appreciated.  Thanks.
