Persistence in Dealing with a Sticky Issue, Luan stayed with the case following up with engineering to ensure they resolved the issue. It was a very tricky case which required dev teams to get invovled, and he followed up with them to make sure they finally got it solved.

Danielle M. was AMAZING! I was really concerned regarding an issue with our most recent email campaign and I reached out to Klaviyo chat support. Danielle M. was incredibly patient, extremely knowledgeable, and made sure to answer every question I had to ensure I was feeling confident by the end of the chat. It truly was one of the BEST chat experiences I have ever had! Agents like Danielle M. are what keep me using Klaviyo. Danielle is an amazing employee! I am truly so impressed with their chat responses and for taking the time to help me and make me not feel rushed. I wish every chat agent was like Danielle M. - you are lucky to have her working for Klaviyo and representing your company so well!
