Create or manage an email account
A professional mailbox uses your business domain. Account creation and storage are limited by the purchased hosting package.
A professional mailbox uses your business domain. Account creation and storage are limited by the purchased hosting package.
1. Check the domain and plan
Confirm the domain is attached to the correct hosting account and that you have enough mailbox capacity. Buying a domain alone does not always provide email hosting.
2. Open Email Accounts
From the cPanel Email group, select Email Accounts. Choose Create when available.
3. Set the mailbox address
Select the intended domain, choose a mailbox name such as info or sales, and create a strong unique password or follow the provider's secure-password option.
4. Review quota and setup
Select suitable storage within the package limits. Save, then use Check Email to access Webmail.
5. Test sending and receiving
Send a message to an external address and reply. If delivery fails, check DNS mail routing, quota, authentication records and provider instructions before changing MX, SPF, DKIM or DMARC.
Check the domain, mail routing and plan first
A domain name alone does not guarantee that a mailbox can be created. Confirm that the domain appears in the correct cPanel account, that your package includes email hosting, and that there is space for another mailbox. If email is hosted by Microsoft 365, Google Workspace or another provider, creating a cPanel mailbox may not change where incoming messages are delivered.
If an existing domain is already receiving mail, identify its current MX records and mail provider before changing Email Routing or DNS. Switching mail providers without a migration plan can interrupt new messages or leave old mail in the previous mailbox. Ask the current provider about migration and cutover steps before changing the route.
Create a mailbox and set a sensible quota
Open Email Accounts in cPanel and select Create. Choose the intended domain from the domain list, enter only the part before @ as the username, and verify the complete address shown before confirming. Use a unique strong password. Do not send it in plain email, website chat or an unencrypted note; provide it to the mailbox user through an approved secure method.
Set a storage quota that fits the purchased package and expected mail volume. A per-mailbox limit is not necessarily the full account disk limit, and “unlimited” in one interface may still be constrained by the hosting plan or provider policy. Leave room for growth and tell mailbox users what to do when they approach the limit.
Test access and connect devices
After creation, use Check Email or the provider’s secure Webmail address to sign in. Send a test message to an external address, then reply to it. This checks both directions more clearly than sending only between two mailboxes on the same server. If one direction fails, keep the exact error or bounce message and ask the host to check the domain’s routing and delivery logs.
To configure a phone or mail client, use Connect Devices beside the mailbox. Follow the secure settings displayed for that account. Prefer IMAP when you want messages and folders synchronized across Webmail and several devices; use POP only when you understand how that client stores or removes server messages. Do not use server names or port numbers from an unrelated provider’s example.
Manage changes without losing mail
The Manage action can update account settings such as password and quota. When a user leaves or a device is lost, change the mailbox password and remove old device sessions or client access where available. Test the new password on a trusted device and notify the authorized user through a separate channel.
Deleting an email account is destructive: messages and account data can be permanently removed. Before deletion, confirm the address, export or migrate needed messages, update any website forms or account logins using it, and obtain the mailbox owner’s approval. If the goal is only to stop one device from connecting, change the password or remove that device instead of deleting the mailbox.
Questions people often ask
Will creating a cPanel mailbox move my domain’s email to cPanel?
Not by itself. Incoming delivery follows the domain’s MX routing. Confirm the current mail provider and MX records before making any routing change.
What should I use for a phone or computer setup?
Open Connect Devices for the specific mailbox and follow the account’s current secure settings. Server names and ports vary by provider; avoid guessed settings.
