If you use Gmail, it's possible to merge your accounts so all emails appear in one inbox, making it easier to stay on top of all your messages.
Simply open Google Mail, click the menu button, and then press 'Link Inboxes'. Then select the inboxes you want to link up, and your emails from those accounts will appear in one place.
Depending on the client you are using, the setup will be different, but normally you need the following settings.
Username: your complete email address
Password: the one you chose when you created your account
Incoming server: imap.one.com
Incoming server port: 993 + SSL
Outgoing server: send.one.com
Outgoing port: 587 + TLS/SSL/STARTTLS (or 465 + SSL/TLS)
Outgoing server authentication: username and password, same as the incoming server
I recommend using IMAP to set up your email account because it syncs your emails across all your devices and Webmail. Unlike POP, which downloads your emails and removes them from the server and Webmail.
If you really want to use POP, you need these settings for the incoming server: pop.one.com
- port 995 - SSL.
