Where can I see my login URL?

Where can I see my login URL?

I'm using Mail hosting on Zoho Mail.
But I forgot the login URL for my domain.
So, where can I see the curent setting for login URL of my domain on the Zoho Mail control panel?

....And,
I know the URL of my old another domain.
That is tailing with "?rd=examplecom.business.zoho.com".
So I tried to login with replacing "examplecom" to my domain name without periods.
BUT that leads me to, oh god, sasizr-dev-ed.my.salesforce.com
