Hi there @pedroalbaladejo,

There are shortcodes available for the Email and Name of the subscriber as described in our documentation here:
https://kb.mailpoet.com/article/215-personalize-newsletter-with-shortcodes

However, for dynamically generating URLs like you are trying to do, we’ve seen issues where doing that with the shortcodes won’t work due to the way URLs are re-written when rendering the email (particularly if any tracking is enabled, since those URLs will be completely re-written).

Instead, it will be necessary to generate the desired URL in code using a custom shortcode as you mentioned. We have a guide for this here:
https://kb.mailpoet.com/article/160-create-a-custom-shortcode

If you need help with custom code for that, we recommend reaching out to someone from Codeable: https://codeable.io

I already found out how to edit your code example:

add_filter('mailpoet_newsletter_shortcode_link', 'mailpoet_custom_shortcode_referral_link', 10, 5);

function mailpoet_custom_shortcode_referral_link($shortcode, $newsletter, $subscriber, $queue, $arguments) {
  // always return the shortcode if it doesn't match your own!
  if ($shortcode !== '[link:referral]') return $shortcode;
  
    $email = $subscriber->getEmail();
    $name = $subscriber->getFirstName();

  $referral_link = "https://example.com/thanks/?email={$email}&name={$name}";
  
  return $referral_link;
}

Thanks anyway
