How to Create Business Email Accounts (you@yourdomain.com) in StackCP

A professional email address on your own domain — rather than a generic Gmail or Yahoo address — makes a real difference to how customers perceive your business. StackCP makes creating one genuinely quick, with immediate webmail access through Stackmail, StackCP's built-in webmail service.

Step 1: Create the Mailbox

1. Log in to StackCP.
2. Go to Manage Hosting, then select Manage on the package you want to add email to.
3. Select Email Accounts under the Email section.
4. Enter the name you want your mailbox to have (the part before the @ symbol) and select the correct domain from the dropdown.
5. Select Create Email Account.

A password is automatically generated for you. You can change it to anything you prefer immediately after the account is created.

Step 2: Understand the Timing

You'll have immediate access to webmail and can send mail right away. However, it can take up to 30 minutes before the mailbox is fully able to start receiving mail — worth knowing so you're not concerned if a test email doesn't arrive instantly.

Step 3: Access Your Webmail (Stackmail)

1. From the Email Accounts screen, select Options > Webmail next to your mailbox for instant, single-sign-on access.
2. Alternatively, there's a general Webmail page under the Email section listing all your mailboxes, each with a direct login link.

Inside webmail, you'll find a Mail tab (your inbox and folders), a Contacts tab, and a Settings tab — where you can add a signature, set up an autoresponder, or change your password.

Step 4: Connect an Email App (Optional)

If you'd rather use Outlook, Apple Mail, or a mobile mail app instead of (or alongside) webmail, use these settings:

• IMAP (incoming): imap.stackmail.com
• SMTP (outgoing): smtp.stackmail.com
• Username: your full email address
• Password: your mailbox password

See our companion guides on connecting Stackmail to specific apps for detailed platform-by-platform steps.

Step 5: Understand Your Storage Allowance

Each mailbox comes with 10GB of storage by default. If a mailbox is approaching or has reached its limit:

1. Go to Manage Hosting > Options > Manage > Email Accounts.
2. Find the mailbox with high usage — you'll see an option to upgrade.
3. You can add extra 10GB blocks as needed, or move to a Premium Mailbox (50GB), which is usually the more cost-effective option if you expect to need significantly more space long-term.

For the most current usage figure (the account list updates only periodically), go to Options > Webmail for that mailbox — the up-to-date usage is shown in the bottom left.

Step 6: Create a Mailbox Even Without Hosting (If Needed)

If a domain doesn't have a hosting package attached, you can still create a mailbox for it: go to Manage Domain Names, select Manage next to the relevant domain, and you'll find an Email Accounts option there as well.

Common Mistakes Beginners Make

• Expecting mail to arrive instantly after creating a new mailbox. Allow up to 30 minutes for receiving to activate — sending works immediately.
• Not changing the auto-generated password, or not storing it securely once changed.
• Not checking storage usage until a mailbox is already full, at which point new incoming mail can bounce. Check periodically, especially for high-volume mailboxes.
• Assuming general webmail login details work without the correct app-specific server settings when setting up a mail client — always use imap.stackmail.com and smtp.stackmail.com specifically.

Troubleshooting

"I created a mailbox but I'm not receiving test emails yet." Wait up to 30 minutes before assuming there's a problem — this is expected behaviour for a newly created mailbox.

"My mailbox says it's full." Check usage via Options > Webmail (bottom left) for the current figure, then either clear out unnecessary mail (including your Trash folder, which still counts toward storage) or upgrade your storage via Email Accounts.

"I can't connect via Outlook/Apple Mail." Double check you're using imap.stackmail.com and smtp.stackmail.com exactly, along with your full email address as the username.

Why a Business Email Address Matters

A generic address like yourbusiness123@gmail.com doesn't inspire the same confidence as hello@yourbusiness.com. For any business accepting customer inquiries, sending invoices, or communicating professionally, a domain-based email address:

• Reinforces your brand every time you send a message.
• Looks more credible to customers, partners, and suppliers.
• Keeps your business communication separate from personal accounts.
• Makes it easy to create role-based addresses (sales@, support@, info@) that can be managed or reassigned independently of any one person.

Choosing the Right Mailbox Structure for Your Business

Before creating every mailbox at once, it's worth thinking briefly about structure:

• Role-based addresses (info@, sales@, support@) are useful for anything customer-facing, since they don't need to change if the person handling them changes.
• Named addresses (priya@, rahul@) suit individual staff members for direct, personal correspondence.
• A mix of both is common — role-based addresses for general inquiries, named addresses for specific team members, often with forwarders (covered in our companion Email Forwarders guide) connecting the two so role-based mail still reaches the right person.

A Practical Setup Checklist for a New Business

If you're setting up email for a new business from scratch, a sensible order is:

1. Create your primary role-based mailbox (e.g., info@yourdomain.com) first.
2. Set a strong, unique password immediately after creation.
3. Connect it to whichever app you'll actually check daily — webmail, Outlook, or a mobile mail app.
4. Set up DKIM (see our companion guide) to improve deliverability of outgoing mail.
5. Create any additional role-based or named mailboxes you need.
6. Consider a catch-all forwarder (see our companion guide) so mail sent to a slightly misspelled or unrecognized address on your domain isn't simply lost.

Security Habits Worth Building From Day One

Because a business email account is often the recovery method for many other accounts (banking, domain registrar, social media, payment gateways), it's worth treating its security seriously from the start:

• Use a strong, unique password rather than the auto-generated one only if you're confident you'll store it securely — otherwise, the auto-generated password is often stronger than one a person would choose manually.
• Avoid reusing your email password anywhere else.
• If you ever suspect unauthorized access, change the password immediately from the Email Accounts screen and review your Junk Mail Filters and forwarder settings for anything unexpected that may have been added.
