Je recommande à 100% Klaviyo, solution CRM très performante, facile à utiliser, avec une toujours une roadmap de nouvelles fonctionnalités impressionnante. J'apprécie également tout particulièrement le support apporté aux clients, que ce soit via la Klaviyo Academie, avec de nombreux articles et vidéos, ou via le support chat ou email, toujours très réactif et à l'écoute. Enfin, mention spéciale pour les CSM, au top de l'accompagnement client!

Support is terrible. 24/5 live chat is unmanned through out the week. Email support is extremely slow and keeps sending useless articles. The data is helpful. The only reason we stayed is because Omnisend doesn't have A/B test for emails

I’d been banging my head against a wall trying to sort out a Klaviyo issue, and Danielle from CS just got it. Super clear, patient, and actually helpful — no waffle. She made something that felt impossible finally make sense. Honestly, couldn’t have done it without her.

Newer user but so far lightyears beyond our experiences with Constant Contact and MailChimp! Ease of setup and deliverability have both been much better not to mention the design templates are pretty great out of the box.

Happy with the results and how easy Klaviyo is to use. Our business, DMEsuperstore.com, supplies necessary medical needs and we needed a tool that can deliver regular messages based on what a customer purchases so we utilize the automatic email flows heavily. They are by far the most rewarding campaigns. Very pleased. Thank you for the support

User friendly, advanced benchmarking and personalization, and increase in revenue. I can't wait to tap into reviews and SMS. This has made connecting our product with consumers easier and more intentional. As a newer employee and coming from a company that primarily used MailChimp, I was prepared to spend quite a bit of time learning a newer platform, but I was pleasantly surprised. Tutorials, support from Jamie, and Klaviyo being so user friendly have all meant that I could hit the ground running and achieve success sooner. My biggest recommendation? Start using Klaviyo ASAP.

This app does absolutely everything I could ever need for my business. There are many things I haven't even tried out yet, but as I get more comfortable, I definitely will. The help is amazing, from the articles through the AI and the live chat. Strongly recommend!
