Web mail site, not sure if it's still the same or not...

[AnaMontenegro]

Hi everyone, I don't know if this is the right place to post this, but I really need some help.

 

Years ago I made an email account on https://unseen.is/ meanwhile they shut down business unfortunately, since that email email wasn't "mission critical" I wasn't too worried.
While I was updating some of my passwords recently, I noticed that https://mail.unseen.is/ does redirect me to a page that is now owned by Zimbra? I tried to look into it and I found out a https://www.unseen.tw/  website that has the same look as the original one I signed up to.

 

I tried to do some detective work to see what's what but I came up empty handed, I was looking for someone more clever than me that could have a look and tell me what is what, I don't wanna input my old credentials in any of those websites until I am sure they are legitimate, I would like to get those emails up and running again if it would be possible, any help would be appreciated.
