Cloze does not support POP email.

Cloze supports all of the modern email providers including Gmail, Google Apps email for Work, iCloud, Microsoft Exchange, Office 365 email, Outlook.com, Yahoo!, AOL and any email service that supports IMAP.

Here are instructions for connecting your email accoun to Cloze

Most major email providers support IMAP because it provides a better method to access your mail from multiple devices. If you check your email at home, on your mobile phone, and again at work, IMAP ensures that new mail is accessible from any device at any time.

Cloze analyzes your relationships and interaction patterns to learn who is important to you - the Cloze Score. To do this it needs to analyze both sent and received email. POP only allows access to received email, so Cloze can't create a picture of your relationships (a spammer that sends you 50 messages you never respond to would look just like someone you interact with constantly).

What does this mean for Cloze? With a POP email account connected your Cloze Scores would all likely be low or zero meaning that we couldn't prompt you the Agenda with reminders to get in touch or priovide relationship-based prioriziation of your Inbox or Social media.
