This article applies to both the new Private Email webmail and the legacy (Open-Xchange) webmail.
This guideline provides instructions on how to set up your Namecheap Private Email mailbox mailbox in Vivaldi Mail – an email client built-in Vivaldi Browser which is available for Windows, Mac, Linux, Android, and iOS.
NOTE: Before setting up a mailbox in the email client, please double-check that your domain name has the correct Private Email DNS records and that the mailbox has been created.
- In your Vivaldi browser, go to Settings (gear icon in the bottom right corner):

In a new window select the Mail section. If you had mail accounts added before, you will need to click on the plus (+) first. If not, just click on the Manual Setup button:

- Now, fill in the settings for your email account as shown below:
Email address: your Private Email address (we use test@nctest.us in this tutorial)
For IMAP:
Incoming server: mail.privateemail.com (please note that it should not be changed)
Port for incoming server: 993
Connection Security: SSL/TLS
Outgoing server: mail.privateemail.com (please note that it should not be changed)
Port for outgoing server: 465
Connection Security: SSL/TLS
For both incoming and outgoing settings:
Username: your full email address (we use test@nctest.us in this tutorial)
Password: password for this mail account

Verify that you imputed the correct details and click Add Account.
- Wait a moment, and your account will be added - it will appear in the list of accounts to the left. Here you can also fill in some settings for this account:
Sender name - the one that will be shown to your customers;
Account display name - how you name this account in your email client;
Signature - customize your emails with a unique signature.

- To check your email account you just need to click on the Mail icon in the browser sidebar and click on your Inbox:

Your mailbox is ready.
That’s it!
