Formatage Service Mail Automatic-Trustpilot/Drupal

Bonjour,
J'ai besoin de mettre en place le Service Mail Automatique chez TrustPilot (coller le code html assez compliqué) sur ma plateforme Drupal de ventes de formations en ligne.
Je souhaite que la personne ait déjà travaillé sur le même souci / formatage.
Merci
Shelley

Hello,
I'm looking for a Drupal expert who will look after my website TeachingEnglishGames.com, implement updates, and do occasional tasks when needed. Right now I have signed up with Trust Pilot and I need their code to be inserted into my website, so that purchasers receive an automatic email 10 days after purchase asking for an evaluation.

Kind regards
Shelley Ann Vernon
