Pour gagner en précision, ajoutez au prompt les métriques complémentaires : taux de rebond, plaintes spam, délivrabilité (boîte de réception vs spam) sur la même période. Cela permettra de distinguer un problème technique d'un simple décalage d'audience. Variante utile : demandez une analyse segmentée par type d'envoi (newsletter, promo, cycle de vie) afin d'isoler la variable qui a réellement impacté l'engagement.
