SendGrid Clicktracking Issue

—

### **Possible Issues and Solutions**
#### 1. **Header Misconfiguration**
– **Problem:** The `clicktracking=off` directive might not be set correctly in the email headers.
– **Solution:** Ensure that you are setting the header properly in your SendGrid API call or SMTP settings. For example:
– **API Example:**

{
         "tracking_settings": {
           "click_tracking": {
             "enable": false
           }
         }
       }

– **SMTP Example:** Add the following header to your email:

X-SG-EID: clicktracking=off

#### 2. **Overriding by Template Settings**
– **Problem:** If you're using a SendGrid template, its settings might override your API or SMTP-level configuration.
– **Solution:** Check your template settings in the SendGrid dashboard and disable click tracking there.

#### 3. **Account-Level Settings**
– **Problem:** The account-level setting for click tracking might still be enabled.
– **Solution:**
– Go to the **SendGrid Dashboard**.
– Navigate to **Settings > Tracking**.
– Disable **Click Tracking** if it is enabled.

#### 4. **Email Encoding Issues**
– **Problem:** The `clicktracking=off` directive might not be interpreted properly due to encoding issues.
– **Solution:** Verify that your email headers and body are correctly encoded and follow the MIME standards.

#### 5. **SendGrid API Key Permissions**
– **Problem:** The API key you're using might not have sufficient permissions to disable click tracking.
– **Solution:** Check your SendGrid API key permissions and ensure it has access to modify tracking settings.

#### 6. **Cache or DNS Issues**
– **Problem:** Changes in tracking settings might not take effect immediately due to caching or DNS propagation.
– **Solution:** Wait for a few minutes and test again. If you’re using a DNS-related setting, ensure your records are correctly updated.

#### 7. **Logging and Testing**
– Enable verbose logging or review the email payload sent to SendGrid to confirm the `clicktracking=off` directive is included.
– Test with a different email client or recipient to ensure the issue is not client-specific.

—

If these steps don't resolve the issue, you may need to contact **SendGrid Support** for assistance. Provide them with the email payload or message ID for further analysis.

—

### **1. Disable Click Tracking for All Emails (Account-Level Setting)**
If you want to disable click tracking for all emails sent from your account:

1. Log in to your **SendGrid Dashboard**.
2. Navigate to **Settings > Tracking**.
3. Find the **Click Tracking** section.
4. Toggle **Click Tracking** to **Off**.

This ensures SendGrid doesn’t modify URLs in any email sent from your account.

—

### **2. Disable Click Tracking for Specific Emails (API or SMTP Settings)**

#### **Via the SendGrid API**
When sending an email via the SendGrid API, include the `tracking_settings` object in your payload to disable click tracking for that specific email:

{
  "personalizations": [
    {
      "to": [{ "email": "example@example.com" }]
    }
  ],
  "from": { "email": "your-email@example.com" },
  "subject": "Example Subject",
  "content": [
    {
      "type": "text/plain",
      "value": "This is the email body."
    }
  ],
  "tracking_settings": {
    "click_tracking": {
      "enable": false
    }
  }
}

—

#### **Via SMTP**
If you're using SendGrid SMTP, add the following header to your email:

X-SG-EID: clicktracking=off

—

### **3. Disable Click Tracking in Templates**
If you're using a **SendGrid Dynamic Template**:

1. Go to the **SendGrid Dashboard**.
2. Open the template you're using under **Email API > Dynamic Templates**.
3. Check for any specific settings within the template related to tracking.
4. Ensure no tracking overrides are set for the URLs in the template.

—

### **4. Ensure No Account-Level Overrides**
Even if you disable tracking at the email or template level, the account settings might still override. Verify this by:

– Ensuring click tracking is globally disabled (see step 1).
– Testing by sending a sample email to confirm that URLs are no longer altered.

—

### **5. Use Plain Text Emails**
SendGrid typically doesn’t alter URLs in plain-text emails unless click tracking is explicitly enabled. If you don’t need HTML formatting, consider sending your email as plain text.

—

### Testing After Changes
– Send a test email to yourself.
– Inspect the email headers or URL links in the received email.
– Ensure URLs remain unaltered (not wrapped in `https://u123456.ct.sendgrid.net/…`).

By following these steps, you can prevent SendGrid from modifying URLs in your emails.

—

### **1. Disable Click Tracking in SendGrid**

#### **Account-Wide (Recommended for Simplicity)**
1. Log in to the **SendGrid Dashboard**.
2. Navigate to **Settings > Tracking**.
3. Toggle **Click Tracking** to **Off**.

This ensures that all URLs, including WordPress password reset links, are not altered by SendGrid.

#### **Email-Specific Setting**
If you only want to disable click tracking for specific emails (e.g., password reset emails), you need to configure your integration.

– **If using a plugin (e.g., WP Mail SMTP with SendGrid):**
– Check the plugin settings for an option to disable click tracking.
– If not available, add the following code to your WordPress site:

add_filter('wp_mail', function ($args) {
        $args['headers'][] = 'X-SG-EID: clicktracking=off';
        return $args;
    });

This adds the necessary header to prevent click tracking for all WordPress emails.

—

### **2. Ensure the Reset URL Remains Unaltered**
SendGrid might still wrap links if the email content is sent in a way that doesn’t respect your tracking settings. Here’s how to fix that:

#### **Plain Text Email**
By default, WordPress sends password reset emails as plain text. SendGrid generally doesn’t wrap URLs in plain text emails unless click tracking is explicitly enabled.

– If you’ve customized your password email to use HTML, ensure the `tracking_settings` or `clicktracking=off` is applied.

#### **Custom Password Reset Email Template**
If you're customizing the email template (e.g., using plugins like **Theme My Login** or writing custom code), ensure the URL is included as-is. For example:

$message = sprintf(
    'Hello, please reset your password by clicking the following link: %s',
    esc_url($reset_url)
);
wp_mail($user_email, 'Reset Your Password', $message);

Ensure no additional HTML or encoding modifies the `$reset_url`.

—

### **3. Debugging and Testing**
– **Send Test Emails:** Use a test user account to trigger a password reset and inspect the email. Verify that the URL isn’t wrapped by SendGrid (i.e., it doesn't look like `https://u123456.ct.sendgrid.net/…`).
– **Check SendGrid Activity:** In the SendGrid dashboard, review the activity logs to confirm no click tracking is applied to these emails.

—

### **4. Alternative Solutions**
If SendGrid continues to alter links, consider:
– **Switching Email Plugins:** Use plugins like **Post SMTP** or **WP Mail SMTP** with better control over headers.
– **Using a Different Email Provider:** Use a service like Amazon SES or Mailgun that gives more granular control over tracking.

By following these steps, you can ensure WordPress password reset emails retain unaltered URLs, providing a seamless user experience.

—

### **1. Use `data-sg-no-track` Attribute**
If you're sending HTML emails, you can prevent specific URLs from being tracked by adding the `data-sg-no-track="1"` attribute to the “ tag. This will exclude the link from SendGrid’s click tracking.

#### Example:

$message = sprintf(
    '<p>Hello,</p>
     <p>Please reset your password by clicking the following link:</p>
     <a href="%s" data-sg-no-track="1">Reset Password</a>',
    esc_url($reset_url)
);
wp_mail($user_email, 'Reset Your Password', $message, ['Content-Type: text/html']);

—

### **2. Manually Exclude Links from Tracking**
If you are using a WordPress plugin (like WP Mail SMTP or another SendGrid integration) to send emails, you’ll need to:

– Modify the email template for password resets.
– Add `data-sg-no-track="1"` to the password reset link in the template.

If you're using a custom mailer or your own WordPress function, ensure your password reset link uses this attribute.

—

### **3. SendGrid Event Webhook for Custom Logic**
If you cannot modify the HTML of the email directly, you can implement custom handling using SendGrid’s Event Webhooks. Here’s how:

1. Enable **Event Webhooks** in your SendGrid account.
2. Add a handler to detect and process click events.
3. Ignore or customize click tracking for specific URLs, like your WordPress password reset link.

—

### **4. Use Custom Redirects**
If you want click tracking for password reset links but need the URL to appear unaltered in the email, consider using a custom redirect mechanism:
– Create a script on your server (e.g., `/no-track-redirect.php`) that immediately redirects to the password reset link.
– Use this URL in your email instead of the raw password reset link.

Example:

#### Redirect Script (`no-track-redirect.php`):

<?php
// Fetch the actual reset URL (e.g., from a query string or database).
$reset_url = $_GET['redirect_to'] ?? '';
if ($reset_url) {
    header("Location: " . urldecode($reset_url), true, 302);
    exit;
}

#### Email Example:

$redirect_url = 'https://example.com/no-track-redirect.php?redirect_to=' . urlencode($reset_url);
$message = sprintf(
    '<p>Please reset your password by clicking the following link:</p>
     <a href="%s">Reset Password</a>',
    esc_url($redirect_url)
);
wp_mail($user_email, 'Reset Your Password', $message, ['Content-Type: text/html']);

This approach ensures that SendGrid tracks the redirect URL, not the actual password reset URL.

—

### **5. Use Dynamic Templates (Selective Tracking Control)**
If you're using SendGrid’s **Dynamic Templates**, you can apply selective tracking settings at the template level:
1. Edit the template in the SendGrid dashboard.
2. Locate the password reset link and manually add `data-sg-no-track="1"`.

—

### Testing:
1. Send a test password reset email.
2. Inspect the received email’s HTML source to ensure:
– The password reset URL is not wrapped by SendGrid’s tracking.
– Other URLs in the email are still wrapped for click tracking.

—

By selectively adding the `data-sg-no-track` attribute or using a redirect mechanism, you can maintain click tracking for most URLs while excluding critical ones like password reset links.

—

### **Step 1: Modify the WordPress Password Reset Email**
By default, WordPress uses the `retrieve_password` function to send the password reset email. You can hook into this and customize the email content to add the `data-sg-no-track` attribute to the password reset URL.

#### Add a Custom Filter for the Password Reset Email
Place the following code in your theme’s `functions.php` file or a custom plugin:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    // Generate the password reset URL
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login');
    
    // Customize the email message
    $message = sprintf(
        '<p>Hello,</p>
         <p>Someone has requested a password reset for your account. If this was you, click the link below to reset your password:</p>
         <p><a href="%s" data-sg-no-track="1">Reset Password</a></p>
         <p>If you didn't request this, you can safely ignore this email.</p>',
        esc_url($reset_url)
    );

    // Set email content type to HTML
    add_filter('wp_mail_content_type', function () {
        return 'text/html';
    });

    return $message;
}, 10, 4);

—

### **Step 2: Ensure the Content Type Is Set to HTML**
WordPress sends plain-text emails by default. The above code adds an HTML filter for password reset emails. If you want HTML emails for all WordPress emails, use:

add_filter('wp_mail_content_type', function () {
    return 'text/html';
});

This ensures all emails sent from WordPress are in HTML format, which supports the `data-sg-no-track` attribute.

—

### **Step 3: Test the Customization**
1. Trigger a password reset email by using the "Forgot Password" feature on the WordPress login page.
2. Check the received email’s source code to ensure the link looks like this:

<a href="https://example.com/wp-login.php?action=rp&key=abc123&login=user" data-sg-no-track="1">Reset Password</a>

3. Verify that:
– The link is clickable and works as expected.
– The URL is not altered by SendGrid.

—

### **Step 4: Apply the Same Logic for Other Emails (Optional)**
If other WordPress emails include sensitive links that should not be tracked, you can follow a similar approach:

#### Example for Custom Emails:

add_action('phpmailer_init', function ($phpmailer) {
    // Modify email body to include `data-sg-no-track` for specific links
    $phpmailer->Body = str_replace(
        'https://example.com/sensitive-link',
        '<a href="https://example.com/sensitive-link" data-sg-no-track="1">Sensitive Link</a>',
        $phpmailer->Body
    );
});

—

### **Step 5: Use a Plugin (Optional Alternative)**
If you’re not comfortable editing code, you can use a plugin like **WP Mail SMTP** (configured for SendGrid) and customize the email templates using its interface. However, manual code changes provide more control over specific emails.

—

### Summary
By adding the `data-sg-no-track="1"` attribute to specific URLs in WordPress-generated emails, you can prevent SendGrid from altering those URLs while keeping click tracking enabled for other links. All changes remain within your WordPress setup, and no further configuration is needed on SendGrid’s side.

// Customize the email message
$message = sprintf(
'Hello,
Someone has requested a password reset for your account. If this was you, click the link below to reset your password:
Reset Password
If you didn't request this, you can safely ignore this email.',
esc_url($reset_url)
);

// Set email content type to HTML
add_filter('wp_mail_content_type', function () {
return 'text/html';
});

return $message;
}, 10, 4);
Not working'

### Common Reasons and Fixes:

#### 1. **Incorrect Hook or Missing Parameters**
Ensure you're using the correct hook and parameters. The `retrieve_password_message` filter should be triggered for default WordPress password reset emails.

If you're using plugins (like WooCommerce or a custom user management plugin), they might override the default password reset functionality.

#### **Solution: Debug the Hook**
Add a debug log to confirm the hook is being triggered:

add_filter('retrieve_password_message', function ($message, $key, $user_login, $user_data) {
    error_log('retrieve_password_message hook triggered'); // Debugging log

    // Generate the password reset URL
    $reset_url = network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login');

    // Customize the email message
    $message = sprintf(
        '<p>Hello,</p>
         <p>Someone has requested a password reset for your account. If this was you, click the link below to reset your password:</p>
         <p><a href="%s" data-sg-no-track="1">Reset Password</a></p>
         <p>If you didn't request this, you can safely ignore this email.</p>',
        esc_url($reset_url)
    );

    // Set email content type to HTML
    add_filter('wp_mail_content_type', function () {
        return 'text/html';
    });

    return $message;
}, 10, 4);

Check your PHP error log for the message *"retrieve_password_message hook triggered"*. If it doesn't appear, the hook isn't being triggered.

—

#### 2. **Conflict with a Plugin or Theme**
Plugins or themes may override the password reset email. For example, plugins like WooCommerce, Theme My Login, or WP Members replace the default email functionality.

#### **Solution: Disable Plugins for Testing**
1. Temporarily disable plugins that handle user registration or password resets.
2. Retest the password reset process.
3. If the custom message works after disabling a plugin, investigate how that plugin handles password reset emails.

For WooCommerce, for example, you might need to customize its email templates instead.

—

#### 3. **Email Content-Type Override**
The email might still be sent as plain text, despite the filter setting HTML content type.

#### **Solution: Ensure HTML Email**
Ensure that the email content type is not reset after your `wp_mail_content_type` filter. You can test this by forcing the email type globally:

add_filter('wp_mail_content_type', function () {
    return 'text/html';
});

—

#### 4. **Directly Hook into `wp_mail`**
If `retrieve_password_message` isn’t working as expected, you can intercept the `wp_mail` function directly and modify the message:

add_filter('wp_mail', function ($args) {
    if (strpos($args['subject'], 'Password Reset') !== false) {
        $reset_url = ''; // Extract or construct the reset URL from the email body.

        // Replace with custom HTML
        $args['message'] = sprintf(
            '<p>Hello,</p>
             <p>Someone has requested a password reset for your account. If this was you, click the link below to reset your password:</p>
             <p><a href="%s" data-sg-no-track="1">Reset Password</a></p>
             <p>If you didn't request this, you can safely ignore this email.</p>',
            esc_url($reset_url)
        );

        $args['headers'][] = 'Content-Type: text/html'; // Ensure HTML content
    }

    return $args;
});

—

#### 5. **Custom Email Handling Plugin**
If neither approach works, consider using the **WP Mail SMTP** plugin or similar tools, which provide a user-friendly interface for customizing emails, including password reset emails.

—

### Testing
1. Clear your server cache if applicable.
2. Trigger a password reset and inspect the email's content.
3. Check logs for any errors or skipped hooks.

If these steps don’t resolve the issue, let me know any specific plugins you’re using that might impact the password reset process.

1. **SendGrid Email Parsing Mechanism**: SendGrid may not respect the `data-sg-no-track` attribute or the `clicktracking=false` property in the template.
2. **WooCommerce's Email Processing**: The HTML output might be altered after the template is processed.

### **Steps to Resolve**

—

### **1. Ensure Click Tracking Is Not Applied to the Link**
SendGrid might still process URLs regardless of the attributes. Try explicitly setting an HTTP header for emails sent via SendGrid to exempt specific links from tracking.

Add this in your WooCommerce `functions.php` or a custom plugin:

add_filter('woocommerce_email_headers', function ($headers, $email_id, $email) {
    // Add a custom header to disable tracking for the email
    $headers .= "X-SMTPAPI: {"filters":{"clicktrack":{"settings":{"enable":0}}}}rn";
    return $headers;
}, 10, 3);

This disables click tracking for the entire email. If you only want it disabled for specific links, you'll need a more granular approach.

—

### **2. Use Plain Text as a Fallback for Sensitive Links**
If disabling tracking for specific links via HTML is problematic, you can include the sensitive link in plain text, as SendGrid doesn’t track plain text URLs.

Modify the reset link section in `customer-reset-password.php`:

<p>
    <?php esc_html_e( 'Click the link below to reset your password:', 'woocommerce' ); ?><br>
    <a class="link" data-sg-no-track="1" href="<?php echo esc_url( add_query_arg( array( 'key' => $reset_key, 'id' => $user_id, 'login' => rawurlencode( $user_login ) ), wc_get_endpoint_url( 'lost-password', '', wc_get_page_permalink( 'myaccount' ) ) ) ); ?>">
        <?php esc_html_e( 'Reset your password', 'woocommerce' ); ?>
    </a>
</p>
<p>
    <?php esc_html_e( 'If the button does not work, copy and paste the following URL into your browser:', 'woocommerce' ); ?><br>
    <?php echo esc_url( add_query_arg( array( 'key' => $reset_key, 'id' => $user_id, 'login' => rawurlencode( $user_login ) ), wc_get_endpoint_url( 'lost-password', '', wc_get_page_permalink( 'myaccount' ) ) ) ); ?>
</p>

This ensures that if the link is altered, the plain-text version remains intact.

—

### **3. Verify SendGrid Integration**
If you are using a plugin like **WP Mail SMTP** or a direct SendGrid API integration, verify that the integration respects the `data-sg-no-track="1"` attribute. Sometimes, the plugin or integration method overrides your customizations.

– Ensure you’re using the latest version of WP Mail SMTP or your SendGrid integration.
– Check the raw email content in the SendGrid email activity dashboard to confirm how the email is processed.

—

### **4. Use Custom Webhooks for Tracking and Exemption**
If SendGrid doesn’t honor the `data-sg-no-track="1"` attribute, consider handling click tracking with a custom SendGrid Event Webhook:

1. **Enable SendGrid Event Webhooks** in your SendGrid dashboard.
2. Parse the webhook events and selectively ignore tracking for sensitive links.

—

### **5. Debug the Final Email Content**
To confirm the issue lies with SendGrid and not WooCommerce or your modifications, inspect the final email being sent. Use a plugin like **Email Log** to capture the raw email content and verify if the `data-sg-no-track="1"` attribute is present.

—

### **6. Open a SendGrid Support Ticket**
If all else fails, contact SendGrid support. Provide them with:
– The affected email's raw content (HTML version).
– Your SendGrid configuration (click tracking enabled with exemptions).

SendGrid can clarify why URLs with `data-sg-no-track` or `clicktracking=false` are still being altered.

—

By combining these steps, you can identify whether the issue is on WordPress/WooCommerce’s side or SendGrid’s and implement an effective solution.

—

### **Final Steps to Prevent URL Alteration by SendGrid**

#### **1. Use Custom Headers to Control SendGrid Behavior**
You can pass specific settings to SendGrid via the `X-SMTPAPI` header. This can disable click tracking for sensitive emails (e.g., password reset emails) or links.

Add this to your `functions.php`:

add_filter('woocommerce_email_headers', function ($headers, $email_id, $email) {
    // Only target the password reset email
    if ($email_id === 'customer_reset_password') {
        $smtpapi = array(
            'filters' => array(
                'clicktrack' => array(
                    'settings' => array(
                        'enable' => 0 // Disable click tracking
                    )
                )
            )
        );

        $headers .= "X-SMTPAPI: " . json_encode($smtpapi) . "rn";
    }

    return $headers;
}, 10, 3);

This approach disables click tracking for the entire password reset email, ensuring URLs remain intact.

—

#### **2. Encode the Link to Bypass Alteration**
Another workaround is to encode the password reset link in a way that prevents SendGrid from recognizing it as a clickable URL:

<p>
    <?php esc_html_e( 'Click the link below to reset your password:', 'woocommerce' ); ?><br>
    <?php echo '<a href="' . htmlspecialchars( esc_url( add_query_arg( array( 'key' => $reset_key, 'id' => $user_id, 'login' => rawurlencode( $user_login ) ), wc_get_endpoint_url( 'lost-password', '', wc_get_page_permalink( 'myaccount' ) ) ) ) ) . '" data-sg-no-track="1">Reset your password</a>'; ?>
</p>

This ensures the link’s structure remains untouched, but it might render differently depending on email clients.

—

#### **3. Generate Plain Text Emails**
SendGrid generally avoids altering URLs in plain-text emails. Modify WooCommerce to send the password reset email in plain text only:

add_filter('woocommerce_email_content_type', function ($content_type, $email_id) {
    if ($email_id === 'customer_reset_password') {
        return 'text/plain'; // Force plain text for password reset
    }

    return $content_type;
}, 10, 2);

With plain-text emails, SendGrid will not wrap or modify URLs.

—

#### **4. Log and Inspect the Email Sent**
To confirm whether your modifications are applied before SendGrid processes the email:

1. Install a plugin like **Email Log** or **WP Mail Logging**.
2. Trigger a password reset email.
3. Inspect the logged email to confirm:
– `data-sg-no-track="1"` is present in the HTML version.
– No additional headers or modifications are made before the email leaves WordPress.

—

#### **5. Contact SendGrid Support**
If the above methods still fail, SendGrid’s click tracking enforcement might be at fault. Provide them with:
– The email source (HTML and headers) from your WordPress logs.
– The specific URLs and attributes you’re using (`data-sg-no-track="1"`).

Request clarification or a custom configuration for your account to exempt specific URLs.

—

### **Alternative Option: Use a Different Email Service**
If SendGrid’s behavior cannot be overridden and URL alteration is critical for your use case, consider switching to another transactional email provider, such as:
– **Postmark**: Known for respecting unaltered URLs.
– **Amazon SES**: Does not add tracking unless explicitly configured.

—

### Summary
1. Ensure `X-SMTPAPI` headers are passed to disable click tracking.
2. Encode or render links to avoid URL alteration.
3. Test plain-text emails if HTML solutions fail.
4. Contact SendGrid support for clarification or escalation.
