I love Klaviyo! I am an email marketing specialist and love the 1:1 support Klaviyo provides in comparison to other ESPs.

Really good experience with them. Super helpful over email. Their online real-time support can be a tiny bit slow but otherwise great experience.

Hi there, thank you very much for the feedback! Kind regards, Claire
At klaviyo's request, I'm writing this review based on a very positive help desk interaction. My my email lists were not loading new subscribers. Nerkesa resolved the issue very efficiently and with great character. Aside from this experience, klaviyo is a great software package for the price.

They were very helpful. I was trying to add a new analytic (which I didn’t do correctly at all) and they were very patient and helped me through it all until it was working.
