To check your email, visit email.notzen.com.

To set up your email client, follow these instructions:

First we enable IMAP - which will allow your email program to talk to gmail and get your email.
1) Go to email.notzen.com and log in with your username/password.
2) Click on the Settings link at the top right.
3) Click on Forwarding and POP/IMAP.
4) Click on Enable IMAP.
5) Click on Save Changes.

Next we set up your client.  Go back to Settings -> Forwarding and click on the email client you want to set up.

The basic settings are:
Incoming Mail (IMAP) Server - requires SSL: imap.gmail.com
Use SSL: Yes
Port: 993
Outgoing Mail (SMTP) Server - requires TLS: smtp.gmail.com (use authentication)
Use Authentication: Yes
Use STARTTLS: Yes (some clients call this SSL)
Port: 465 or 587
Account Name: your notzen username (including @notzen.com)
Email Address: your full Gmail email address (username@notzen.com)
Password: your Notzen password

but the page here will give you the specific version for your email client, complete with pictures.
