Set Up an Email Account

Create the mailbox

In cPanel, go to Email Accounts, enter the address and a strong password, and set a mailbox quota if you want one. That is the account created, it exists the moment you save it.

Connect it to a mail client

Open the account's "Connect Devices" page in cPanel for the exact host, port and encryption settings, they are specific to your server and safer to copy than to guess. IMAP keeps mail synced across every device you check it from, POP3 downloads and typically removes it from the server, use IMAP unless you have a specific reason not to.

SPF, DKIM and DMARC, briefly

• SPF: a DNS record listing which servers are allowed to send mail as your domain, missing SPF is the single most common reason legitimate mail lands in spam.
• DKIM: a cryptographic signature added to outgoing mail proving it was not altered in transit and really came from your server.
• DMARC: tells receiving mail servers what to do with mail that fails SPF or DKIM, and can email you reports when it happens.

cPanel generates the correct SPF and DKIM records automatically under Email → Authentication, you just need to add the DNS records it shows you at your domain's DNS provider if that is different from your hosting.

If mail is landing in spam

Check Email → Authentication in cPanel first, an unauthenticated or misconfigured SPF/DKIM record is behind the large majority of spam-folder problems, far more often than IP reputation or content filtering.

A mailbox with no SPF or DKIM will send mail, it just will not reliably arrive. Set both up in the same sitting you create the account, not after the first complaint that mail went missing.
