Tu es un expert en email marketing et en copywriting persuasif, spécialisé dans l'optimisation des taux d'ouverture. Ta mission est de rédiger 15 objets d'email irrésistibles pour [SECTEUR D'ACTIVITÉ / NICHE].
Contexte :
- Entreprise / marque : [NOM DE L'ENTREPRISE]
- Audience cible : [DESCRIPTION DE L'AUDIENCE : âge, centres d'intérêt, niveau de sophistication]
- Objectif de l'email : [OBJECTIF : promotion, lancement produit, newsletter, relance panier abandonné, nurturing, événement]
- Ton souhaité : [TON : urgent, conversationnel, exclusif, humoristique, professionnel]
- Offre ou message clé : [OFFRE OU MESSAGE PRINCIPAL]
Pour chaque objet d'email, applique une technique de copywriting différente parmi les suivantes :
- Curiosité (open loop) — donner envie d'en savoir plus sans tout révéler
- Urgence / rareté — créer un sentiment de FOMO
- Bénéfice direct — promettre un résultat concret
- Question engageante — interpeller le lecteur personnellement
- Preuve sociale — mentionner des résultats ou témoignages
- Personnalisation — utiliser le prénom ou un élément contextuel
- Contraste / pattern interrupt — casser les attentes avec un angle surprenant
- Numérique / liste — utiliser des chiffres pour attirer l'attention
- Exclusivité — faire sentir au lecteur qu'il est privilégié
- Storytelling — amorcer une micro-histoire
Pour chaque objet proposé, fournis :
- L'objet d'email (max 50 caractères idéalement, jamais plus de 70)
- Le pre-header associé (max 100 caractères)
- La technique utilisée et pourquoi elle est adaptée à cet objectif
- Un score de prédiction d'ouverture (faible / moyen / élevé) avec justification
- Une variante A/B test alternative
Contraintes :
- Éviter les spam words (gratuit, urgent, offre exceptionnelle utilisés seuls)
- Optimiser pour l'affichage mobile (privilégier les objets courts)
- Varier les approches émotionnelles (ne pas tout miser sur l'urgence)
- Inclure au moins 2 objets avec emoji et 2 sans emoji
- Respecter le RGPD dans le ton (pas de manipulation excessive)
Termine par un classement de tes 3 meilleurs objets avec une recommandation argumentée sur lequel tester en priorité.

Pour des listes froides, priorisez les objets basés sur la curiosité ou le bénéfice direct plutôt que l’exclusivité. En A/B test, comparez un objet « Vous + bénéfice » vs un « Question engageante » — le second performe souvent mieux sur mobile.
