 ## Usage

-`@push.rocks/smartmail` provides a unified format for representing and dealing with emails in a Node.js environment. Below, you will find several examples showcasing how to use its main features.
-
 ### Importing the Module

-First, ensure you're using ESM (ECMAScript Modules) syntax in your TypeScript project. Then, import the necessary classes:
-
 ```typescript
 import {
  Smartmail,
-  EmailAddressValidator
+  EmailAddressValidator,
+  WireTarget,
+  WireParser,
+  createMessageId,
+  createTimestamp
 } from '@push.rocks/smartmail';
 ```

-## Email Address Validation
+## 🔗 Fluent Chainable API
+
+All mutation methods return `this`, enabling elegant method chaining:

-The Smartmail constructor accepts a generic type parameter that lets you associate any additional data with your email, accessible later via the `getCreationObject()` method. This is useful for tracking, referencing original data sources, or maintaining context:

- Pass the email object between systems while preserving context
- Avoid duplicating data between email content and your application
- Use the reference data to fill template variables
- Access metadata about the email that doesn't get included in the actual message

+// From JSON string
+const email2 = Smartmail.fromJson(jsonString);
+
+// Attachments are automatically reconstructed from base64
+console.log(email2.attachments[0].contentBuffer);
+```
+
+## 🌐 Wire Protocol Classes
+
+For microservice architectures, smartmail provides `WireTarget` and `WireParser` classes to handle client-server communication.
+
+### WireTarget (Client/SaaS Side)
+
+The `WireTarget` is used by your SaaS application to communicate with an SMTP service:
+
+```typescript
+import { WireTarget, Smartmail } from '@push.rocks/smartmail';
+
+// Configure the target endpoint
+const smtpTarget = new WireTarget({
+  endpoint: 'https://smtp-service.example.com/api/wire',
+  authToken: 'your-secret-token'
+});
+
+// Submit SMTP settings (extensible - add any custom settings)
+await smtpTarget.updateSettings({
+  smtp: {
+    host: 'smtp.example.com',
+    port: 587,
+    secure: true,
+    username: 'user',
+    password: 'pass'
+  },
+  defaultFrom: 'noreply@example.com',
+  customSetting: 'custom-value'  // Extensible!
+});
+
+// Send an email using fluent API
+const response = await new Smartmail({
+  from: 'sender@example.com',
+  subject: 'Hello {{name}}',
+  body: 'Welcome!'
+})
+  .addRecipient('user@example.com')
+  .setPriority('high')
+  .applyVariables({ name: 'John' })
+  .sendTo(smtpTarget);
+
+console.log(`Sent! Delivery ID: ${response.deliveryId}`);
+
+// Check delivery status
+const status = await smtpTarget.getStatus(response.deliveryId);
+console.log(`Status: ${status.status}`);  // 'queued' | 'sending' | 'sent' | 'failed'
+
+// List emails in a mailbox
+const inbox = await smtpTarget.listMailbox('INBOX', { limit: 10, offset: 0 });
+console.log(`Found ${inbox.total} emails`);
+
+// Fetch a specific email
+const fetchedEmail = await smtpTarget.fetchEmail('INBOX', 'email-id-123');
+```
+
+### WireParser (Server/SMTP Side)
+
+The `WireParser` is used by your SMTP service to handle incoming wire messages:
+
+```typescript
+import { WireParser, createMessageId, createTimestamp } from '@push.rocks/smartmail';
+
+const parser = new WireParser({
+  // Handle email send requests
+  async onMailSend(email, options) {
+    const mimeFormat = await email.toMimeFormat();
+    await transporter.sendMail(mimeFormat);
+
+    return {
+      type: 'mail.send.response',
+      messageId: createMessageId(),
+      timestamp: createTimestamp(),
+      success: true,
+      deliveryId: generateDeliveryId()
+    };
+  },
+
+  // Handle settings updates
+  async onSettingsUpdate(settings) {
+    if (settings.smtp) {
+      configureSmtpTransport(settings.smtp);
+    }
+    // Handle custom settings
+    if (settings.customSetting) {
+      handleCustomSetting(settings.customSetting);
+    }
+
+    return {
+      type: 'settings.update.response',
+      messageId: createMessageId(),
+      timestamp: createTimestamp(),
+      success: true
+    };
+  },
+
+  // Handle mailbox list requests
+  async onMailboxList(mailbox, options) {
+    const emails = await getEmailsFromMailbox(mailbox, options);
+    return {
+      type: 'mailbox.list.response',
+      messageId: createMessageId(),
+      timestamp: createTimestamp(),
+      mailbox,
+      emails: emails.map(e => e.toObject()),
+      total: emails.length
+    };
+  },
+
+  // Handle email fetch requests
+  async onMailFetch(mailbox, emailId) {
+    const email = await getEmailById(mailbox, emailId);
+    return {
+      type: 'mail.fetch.response',
+      messageId: createMessageId(),
+      timestamp: createTimestamp(),
+      email: email ? email.toObject() : null
+    };
+  },
+
+  // Handle status check requests
+  async onMailStatus(deliveryId) {
+    const status = await getDeliveryStatus(deliveryId);
+    return {
+      type: 'mail.status.response',
+      messageId: createMessageId(),
+      timestamp: createTimestamp(),
+      deliveryId,
+      status: status.state
+    };
+  }
+});
+
+// Express route handler example
+app.post('/api/wire', async (req, res) => {
+  const responseJson = await parser.parseAndHandle(JSON.stringify(req.body));
+  res.json(JSON.parse(responseJson));
+});
+```
+
+### Wire Protocol Message Types
+
+```typescript
+// All available message type interfaces
+import type {
+  IWireMessage,
+  IMailSendRequest,
+  IMailSendResponse,
+  IMailboxListRequest,
+  IMailboxListResponse,
+  IMailFetchRequest,
