The SendInBlue plugin works great! I had a little trouble activating the API key (it was my fault, not SIB's fault). The techs responded to my problem quickly and gave me the solution I needed. I was entering the shortcut for the API instead of the whole key. Anyway, I am very happy with the plugin. It's easy to use and meets all of my needs. It integrates my subscribers quickly so I never miss a contact. And SendInBlue support team is fast, professional, and very helpful in solving my issue.

J'ai eu une mauvaise expérience avec ce service qui m'a couté un bras ! Le service est incapable de détecter des emails frauduleuses et est un repère pour les spameurs. Ils m'ont clairement incité à résilier mon abonnement, ce que j'ai fait. Mais le pompon, c'est que Sendinblue m'a envoyé un email un mois plus tard, me proposant 20€ en carte Amazon si je laissais un avis positif sur ! Les avis que vous voyez ici sont potentiellement faux. Quelle entreprise sérieuse payerait ses propres utilisateurs pour avoir de bons avis sur la plateforme ? Je tiens à préciser que les entreprises qui ont recourt à l'achat de bons avis auprès de leurs clients sur Amazon se sont fait bannir illico. J'espère qu'il en sera de même pour Sendinblue sur WordPress. C'est inacceptable.

I've just tested the process using FluentSMTP, and it literally took me 58 seconds. Delivery is also pretty fast. Let's see if you can beat my crazy tab skills! 😉
