Intent: Investigate delivery requirements and verify message paths before relying on email.
For: business-owner, operator

## Requirements and responsibilities

- Have named ownership of the domain, selected xCloud team and site, and WordPress administrator access. For this scenario, agree who supplies the data and signs off: A store owner notices order emails are inconsistent after the site goes live. Sources: [xCloud agent capability boundaries](https://github.com/xCloudDev/xcloud-agent-skills/blob/main/plugins/xcloud/reference/capability-map.md); [WordPress roles and capabilities](https://wordpress.org/documentation/article/roles-and-capabilities/)
- Use a compatible Nginx or OpenLiteSpeed stack for native WordPress. Verify current server resources, plan eligibility and each selected plugin or service license and requirements before installing; a Docker server does not host a new native WordPress site. Sources: [xCloud agent capability boundaries](https://github.com/xCloudDev/xcloud-agent-skills/blob/main/plugins/xcloud/reference/capability-map.md); [WordPress plugin administration](https://wordpress.org/documentation/article/manage-plugins/)
- Prepare a safe test identity and a completed, accessible backup before consequential changes. The important failure to plan around is: A successful form or order save does not prove message delivery.

## Illustrative situation

Illustrative scenario, not a customer case study: A store owner notices order emails are inconsistent after the site goes live. A test event is recorded and reaches both intended customer and staff inboxes.

## Choose the approach

- Choose a supported mail delivery provider and sender domain using its own documentation. Verify the selected provider or plugin documentation and license against this requirement; xCloud hosting does not supply its business configuration.

- Keep application setup, domain/DNS ownership, mail delivery and external integrations with their named administrators. Use a plain documented path when a proposed integration cannot be demonstrated end to end.

## Dashboard and application procedure

### 1. Map transactional events

**Where:** WordPress public pages and relevant external provider

**Permissions:** Named WordPress or app administrator; business owner signs results.

**Inputs:** Owner, hostname, approved requirements, sample record and decision date. Map transactional events.

**Action:** List WordPress events that send mail: contact submissions, password reset and any store or membership notices. Name sender domain, recipient and originating record for each.

**Expected result:** The site has a test matrix for messages.

**Verify:** The owner confirms which event reaches which mailbox.

**If it fails:** If a message has no owner, keep a visible alternate contact path.

Capability: Review a WordPress business journey

### 2. Inspect sender configuration

**Where:** xCloud Email Provider and site Email Config dashboard; SMTP provider account

**Permissions:** Named SMTP provider and xCloud email administrator; keep credentials private.

**Inputs:** Target team/site, server or plugin version, license and documented prerequisites. Inspect sender configuration.

**Action:** Inspect the WordPress mail plugin, provider account and DNS sender records with authorized access. Determine whether the site uses default PHP mail or a configured transactional service.

**Expected result:** The delivery path and domain owner are known.

**Verify:** Record provider, sender address and DNS status without exposing credentials.

**If it fails:** If the domain is unverified, resolve DNS ownership before production mail.

Capability: Configure WordPress site SMTP provider

### 3. Configure the mail provider

**Where:** xCloud Email Provider and site Email Config dashboard; SMTP provider account

**Permissions:** Named SMTP provider and xCloud email administrator; keep credentials private.

**Inputs:** Approved change scope, backup state, selected version and maintenance window. Configure the mail provider.

**Action:** Use the chosen provider's documented WordPress integration. Keep credentials and suppression settings with a named administrator.

**Expected result:** A controlled test event is accepted by the provider.

**Verify:** Match a unique WordPress event timestamp to the provider acceptance log.

**If it fails:** If rejected, inspect authentication or API errors before changing page copy.

### 4. Trace the delivered message

**Where:** WordPress public pages and relevant external provider

**Permissions:** Named WordPress or app administrator; business owner signs results.

**Inputs:** Test accounts, sample content or transaction, expected result and provider access. Trace the delivered message.

**Action:** Trigger a sample form or sandbox order and inspect destination inbox, spam folder and provider trace. Compare sender, subject and recipient.

**Expected result:** The intended person receives a usable message.

**Verify:** The recipient identifies the unique test marker and originating record.

**If it fails:** If the app saved data but mail failed, treat delivery as failed and use manual follow-up.

### 5. Assign failure handling

**Where:** xCloud Email Provider and site Email Config dashboard; SMTP provider account

**Permissions:** Named SMTP provider and xCloud email administrator; keep credentials private.

**Inputs:** Observed results, unresolved failures, backup point and owner contacts. Assign failure handling.

**Action:** Give staff a procedure for bounces, suppressions and delay, plus a fallback contact route. Include mail tests after plugin and theme updates.

**Expected result:** Mail issues have a response owner after launch.

**Verify:** Have the owner locate the provider log for the latest controlled event.

**If it fails:** If delivery evidence is unavailable, repeat the integration test before relying on it.

## Maintenance

- Assign a cadence for selected WordPress core, theme and plugin updates, review version-based findings and retest the path in this guide. In particular, repeat: A test event is recorded and reaches both intended customer and staff inboxes. A chat prompt is not a scheduled task. Sources: [Manage WordPress updates with Updates Manager](https://xcloud.host/docs/manage-wordpress-updates-with-updates-manager/); [Vulnerability Checker in xCloud](https://xcloud.host/docs/vulnerability-checker-in-xcloud/)
- Record actual backup completion, storage access and responsible staff. Recheck connected application and provider behavior after changes rather than relying on a site health status alone.

## Recovery decisions

- If transactional mail fails, preserve the originating order, form or account event. Have the provider and xCloud email administrators check SMTP credentials, sender-domain records, provider rejection and suppression logs; retest with a marked message. A WordPress database restore is not a mail-delivery repair. Sources: [xCloud WordPress site email with an SMTP provider](https://xcloud.host/docs/setting-up-site-emails-for-wordpress-on-xcloud/)

## AI handoff

Connect xCloud MCP through the current documented profile and grant only the scopes needed for the selected team. Discover tool schemas first. Read resources to plan; require approval for any supported write. Use returned dashboard URLs for manual work. The packaged REST wrapper accepts GET requests only.

### Supported scope

- **Confirm requirements and inspect resources** (mcp; read): Discover the connected profile and operation schema first; only teams granted to the connection are visible. Checkpoint: Confirm exact team, server and site identity. Use dashboard\_url returned by the resource; do not invent a dashboard link. Operation identifiers to discover: teams.index, servers.show, sites.show. Scopes: read:servers, read:sites. Sources: [xCloud MCP documentation and connection profiles](https://app.xcloud.host/mcp/docs); [xCloud agent capability boundaries](https://github.com/xCloudDev/xcloud-agent-skills/blob/main/plugins/xcloud/reference/capability-map.md)
- **Review a WordPress business journey** (app; manual): Application data and observed transactions cannot be inferred from xCloud resource reads. Use authorized test accounts and the application or provider evidence. Checkpoint: Record the test identity, timestamp, expected outcome, observed result and owner decision. Sources: [WordPress roles and capabilities](https://wordpress.org/documentation/article/roles-and-capabilities/)
- **Configure WordPress site SMTP provider** (dashboard; manual): An authorized SMTP-provider account owner supplies its credentials and sender-domain setup; an xCloud administrator configures Email Provider and site Email Config in the dashboard. Mail delivery must be tested separately. Checkpoint: Inspect provider acceptance and mailbox delivery for a marked event; never expose credentials to an agent response.

### Copyable agent brief

```text
Help with add transactional email to a wordpress site for the exact xCloud team and site I name. First inspect only resources the connection permits and confirm returned identity, stack and relevant versions. Prepare the following authored workflow: Map transactional events; Inspect sender configuration; Configure the mail provider; Trace the delivered message; Assign failure handling. Ask the named dashboard, domain, WordPress and application owners to perform operations outside connected capabilities. WordPress staging push/pull, native backup schedules, restore and cache settings remain manual dashboard tasks; the packaged REST wrapper is GET-only. Use the guide’s checks to report observed application evidence, unresolved questions and recovery implications; do not claim completion from a hosting resource read. Acceptance: The intended person receives a usable message.
```

### Manual checkpoints

- The named WordPress, app, dashboard or provider administrator performs the guide’s actual configuration step: Use the chosen provider's documented WordPress integration. Keep credentials and suppression settings with a named administrator.
- The business owner compares the controlled sample with this observable result: The intended person receives a usable message.
- Staging push/pull, native backup schedules, restores and cache-setting edits require the authorized xCloud dashboard operator; the packaged REST wrapper is GET-only.

## Feature coverage

- **business-acceptance** (covered): A test event is recorded and reaches both intended customer and staff inboxes. Steps: phase-4
- **recovery** (covered): A successful form or order save does not prove message delivery. Steps: phase-5
