Don't let this gap widen
Sans maîtrise du protocole SMTP, 65 % des incidents de messagerie professionnelle proviennent d'erreurs de configuration, entraînant des non-livraisons massives d'emails critiques.
Chaque incident coûte en moyenne 3 000 € en temps de support IT et opportunités commerciales perdues, avec des blacklists qui bloquent jusqu'à 80 % des envois pendant des semaines.
Pour une entreprise, cela se traduit par des pertes annuelles de 50 000 € et une exposition accrue aux cybermenaces, compromettant la réputation et la stabilité des équipes IT.
Chaque mois sans expertise SMTP aggrave ces risques, menaçant directement la continuité business et les carrières des administrateurs.
