Emails

The Ultimate Multisite: Emails addon lets network owners provision and manage customer email accounts alongside sites and memberships. Version 1.1.0 adds customer-facing email account management, webmail single sign-on, CyberPanel forwarder support, and checkout-time provisioning improvements.

Key Features​

  • Customer email account widget: Customers can create and manage email accounts from their account page without opening a support ticket.
  • Webmail SSO and magic links: Customers can open webmail directly from the account page with one-click authentication when the provider supports it.
  • Password changes: Customers and administrators can update mailbox passwords from the email management widget.
  • Checkout provisioning: Customer email account creation can run during checkout so the mailbox is ready after the purchase flow completes.
  • CyberPanel forwarders: CyberPanel-backed networks can create and manage email forwarders as part of the email service flow.
  • Provider-aware settings: The settings page filters providers to active, configured integrations so administrators only see usable options.

Requirements​

  • Ultimate Multisite 2.0.0 or higher
  • WordPress Multisite installation
  • At least one configured email provider integration
  • Provider API credentials with permission to create mailboxes, change passwords, and issue webmail access links where supported

Installation​

  1. Upload the plugin files to /wp-content/plugins/ultimate-multisite-emails.
  2. Network activate the addon from Plugins in the WordPress network admin.
  3. Go to Ultimate Multisite > Settings and open the addon email settings.
  4. Enable the email provider integrations you want customers to use.
  5. Save settings, then test account creation with a non-production customer or staging site.

Customer Account Email Management​

Version 1.1.0 adds an email management widget to the customer account page. Use it when customers should self-service mailbox creation and maintenance for their own sites.

From the account page, customers can:

  1. View email accounts connected to their current membership or site.
  2. Create a new mailbox when their plan allows additional accounts.
  3. Change an existing mailbox password.
  4. Open supported webmail providers through SSO or a magic-link login.

The widget uses the Ultimate Multisite account-page currents system, so actions are scoped to the account context the customer is viewing. This prevents customers from managing email accounts that belong to another membership or site.

Webmail SSO gives customers a direct Open webmail action from the account page. When supported by the active provider, the addon requests a short-lived access URL and redirects the customer into webmail without asking them to copy mailbox credentials.

Provider behaviour can vary:

  • Providers with native SSO APIs can create a direct authenticated webmail session.
  • Providers with magic-link support can generate a time-limited login link.
  • Providers without SSO or magic-link support should still show the mailbox details and password-management actions, but no one-click webmail button.

Enable webmail access only for providers where you have configured the required API credentials. If the action is missing for a provider, first confirm that the provider is active, configured, and supports webmail login links.

Checkout Provisioning​

The addon can create customer email accounts as part of checkout. This is useful when the plan includes a mailbox by default or when the checkout form collects email-account details.

Recommended rollout:

  1. Configure the provider and plan limits before enabling checkout provisioning.
  2. Test a purchase with a staging product and confirm the mailbox is created after checkout.
  3. Review the customer account page to confirm the new mailbox appears in the email widget.
  4. Confirm password-change and webmail actions before enabling the flow for production products.

If provisioning fails, the customer account and membership can still exist while the mailbox requires administrator follow-up. Check the Ultimate Multisite activity logs and the provider logs before retrying.

CyberPanel Email Forwarders​

For CyberPanel-backed networks, version 1.1.0 adds email forwarder support. Use forwarders when customers need addresses such as [email protected] to redirect mail to another inbox without creating a full mailbox.

Before offering forwarders, confirm that the CyberPanel integration is configured and reachable. See the CyberPanel Integration guide for the required host, username, password, and package constants.

Frequently Asked Questions​

Can customers create their own email accounts?​

Yes. When the customer account widget is enabled and the plan allows email accounts, customers can create and manage their own mailboxes from the account page.

Does every provider support webmail SSO?​

No. SSO and magic-link support depends on the active email provider. Providers without an access-link API can still support mailbox creation and password changes.

Can administrators create email accounts for customers?​

Yes. Administrators can create email accounts from the admin interface, including setting the initial password when creating the account.

Are forwarders the same as mailboxes?​

No. A mailbox stores mail and has login credentials. A forwarder redirects mail to another address and does not provide a separate inbox.
