Pros As a brand that has both a website and an app, Customer.io combined everything we needed to send customer journey messages across various channels: Push, in-app, email, and sms.

Pros Customer.io gives us complete control over messaging, email, SMS, push, in‑app, with smart workflows and segmentation based on real behavior. It’s configurable, reliable, and great for personalized customer journeys Cons The UI can feel overwhelming at first, especially for non‑technical users, searching for past messages or editing templates isn’t intuitive.

Pros Un super CRM déjà testé et approuvé par le passé. Large possibilté de set up, on peut tourner l'outil dans tous les sens. Cons Après avoir utilisé customer.io à de multiple reprises, je convaincs un de mes clients de passer d'Hubspot à customer.io. Nous paramétrons les campagnes, je demande la vérification du compte, et après quelques échanges avec le service client, plus aucune nouvelle. Mon compte n'est pas validé, je ne peux pas lancer mes campagnes et mes messages au customer service restent sans réponse. La période d'essai fond sous mes yeux.

UI looks good, and no one on my team needed to look at documentation to use it. It was easy for our developers to connect Customer Io into our platform.

Ordinarily, in this situation, we would just go with a different company, but we haven't found one that makes sense. They got us in on their startup program, but that is just a bandaid on their pricing model. Pros It can send emails based on actions triggered within our app. Cons The pricing structure. It assumes clients are B2B businesses, not B2C or e-commerce.
