Password Reset Email Customization

1. **Override the Default Email Template:**
You can customize the password reset email by using the `retrieve_password_message` filter. Add the following code to your theme's `functions.php` file or a custom plugin:

add_filter('retrieve_password_message', 'custom_password_reset_email', 10, 4);

   function custom_password_reset_email($message, $key, $user_login, $user) {
       // Get the password reset URL
       $reset_url = wp_login_url() . "?action=rp&key=$key&login=" . rawurlencode($user_login);
       
       // Add the clicktracking=off attribute
       $reset_url = str_replace('href="', 'clicktracking=off href="', $reset_url);

       // Customize the message
       $message = __('Hello,') . "rnrn";
       $message .= __('Someone has requested a password reset for the following account:') . "rnrn";
       $message .= '<a clicktracking=off href="' . esc_url($reset_url) . '">' . __('Reset your password') . '</a>' . "rnrn";
       $message .= __('If you did not request a password reset, please ignore this email.') . "rn";
       $message .= __('Thank you!');

       return $message;
   }

2. **Testing the Changes:**
– After adding the code, test the password reset functionality to ensure that the email sent contains the modified link with `clicktracking=off`.

3. **Considerations:**
– Ensure that you back up your theme files or use a child theme to avoid losing changes during theme updates.
– This code will add the `clicktracking=off` attribute to the password reset link in the email. Adjust the message format as needed to fit your email design.

This way, any password reset email sent from your WordPress site will have the `clicktracking=off` attribute in the reset link.

Here are a few strategies you can try:

### 1. Use a Plain Text Email

SendGrid allows you to send plain text emails, which typically do not have click tracking applied. You can modify the email to be sent as plain text. Here’s how you can adjust your code:

add_filter('retrieve_password_message', 'custom_password_reset_email', 10, 4);

function custom_password_reset_email($message, $key, $user_login, $user) {
    // Get the password reset URL
    $reset_url = wp_login_url() . "?action=rp&key=$key&login=" . rawurlencode($user_login);
    
    // Customize the message
    $message = __('Hello,') . "rnrn";
    $message .= __('Someone has requested a password reset for the following account:') . "rnrn";
    $message .= __('To reset your password, visit the following link: ') . "rn";
    $message .= esc_url($reset_url) . "rnrn";
    $message .= __('If you did not request a password reset, please ignore this email.') . "rn";
    $message .= __('Thank you!');

    return $message;
}

// Send the email as plain text
add_filter('wp_mail_content_type', function() {
    return 'text/plain';
});

### 2. Disable Link Tracking in SendGrid

If you want to keep using HTML emails but prevent SendGrid from modifying your links, you can disable link tracking directly in your SendGrid settings:

– Log in to your SendGrid account.
– Navigate to **Settings** and then **Mail Settings**.
– Find **Link Tracking** and toggle it off.

### 3. Use a Custom Domain

If you have your own custom domain set up for sending emails, consider using that domain in your password reset URLs. This may help in bypassing some of the link modifications, as the URL will appear more trustworthy.

### 4. URL Shortening

Another approach is to use a URL shortener that you control, which can help avoid tracking modifications. This way, you generate a short URL that redirects to your original password reset link. However, ensure that the shortener doesn’t apply its own tracking features.

### 5. Contact SendGrid Support

If none of the above methods work, consider reaching out to SendGrid support. They can provide specific guidance on how to handle this issue effectively while using their services.

### Conclusion

Implementing these strategies can help you manage the link in your password reset emails more effectively, avoiding any unintended modifications by SendGrid.

### 1. Use URL Parameters for Tracking

Instead of relying on `clicktracking=off`, you can use unique URL parameters to identify the link as a password reset link. This might help to prevent SendGrid from altering it. Modify your code as follows:

add_filter('retrieve_password_message', 'custom_password_reset_email', 10, 4);

function custom_password_reset_email($message, $key, $user_login, $user) {
    // Get the password reset URL with a unique parameter
    $reset_url = wp_login_url() . "?action=rp&key=$key&login=" . rawurlencode($user_login) . "&custom_reset=true";
    
    // Customize the message
    $message = __('Hello,') . "rnrn";
    $message .= __('Someone has requested a password reset for the following account:') . "rnrn";
    $message .= '<a href="' . esc_url($reset_url) . '">' . __('Reset your password') . '</a>' . "rnrn";
    $message .= __('If you did not request a password reset, please ignore this email.') . "rn";
    $message .= __('Thank you!');

    return $message;
}

### 2. Use a Custom Template

If you're using a SendGrid template for your emails, you might have to customize the template itself. Go to your SendGrid account, locate the password reset email template, and ensure that the link is set up as you intend.

### 3. Disable SendGrid Link Tracking via API

If you're sending emails via the SendGrid API, you can disable link tracking in the request itself. Here’s an example using the SendGrid PHP library:

$mail = new SendGridMailMail();
$mail->setFrom("from@example.com", "Example User");
$mail->setSubject("Reset your password");
$mail->addTo($user_email, $user_login);
$mail->addContent("text/html", $html_content);
$mail->addHeader("X-SMTPAPI", json_encode(['asm' => ['group_id' => YOUR_GROUP_ID, 'settings' => ['click_tracking' => ['enable' => false]]]]));

// Send the email
$sendgrid = new SendGrid('YOUR_SENDGRID_API_KEY');
$response = $sendgrid->send($mail);

### 4. Email Client Workaround

As a last resort, if you have control over how the emails are rendered or opened, you can consider advising users to copy and paste the link into their browser instead of clicking it directly.

### 5. Contact SendGrid Support

If you're still encountering issues, it might be best to reach out to SendGrid's support team for assistance. They can provide more tailored guidance on how to prevent their system from altering your links.

### Conclusion

Combining these strategies should help you achieve the desired outcome for your password reset links in WordPress. If you need further assistance, please let me know!
