Best customer service support chat. They are always willling to help!
Tabayer · 5★ · 2025-03-20
every time you contact the chat it is 8 hours, and they are not fully trained and don't have an answer to any technical issue so you have to close and start a new chat hopping you'll get somebody else! no tel support.

Customer Support is available and knowledgeable. Very helpful in working through questions/problems to a successful result.
Bedding Luxuries · 5★ · 2025-10-03
any help at all is reserved for pro. Absolutely horrible customer service because there is none unless you meet a certain requirement. At the very least your app should work as promised, even without support. Edit to respond to the reply: I connected with your team by mistake. Your team immediately told me that they wouldnt help me without looking at the message and told me if I wanted help I'd have to upgrade to pro. They could have read my email acknowledged that it was an error and send me kindly on my way. they did not however do that. Instead they sent a canned response that was completely irrelevant to the email. Which IS the definition of horrible customer service. I use your service and had this experience and decided it was noteworthy to share. I received a nice email response from the founder who addressed the issue. There's a lot of work that needs to be done on ur csr dept.

False pricing plan. If you open pricing plan from the app page, then you will see that you can buy 20$ plan with 5000 emails. However, after installation I've tried to update plan, and the cheapest version is for 140$ only!

A little rocky of a start in the learning process. I think It's a great process but scheduling in time to really understand the interface is important and an investment. Would recommend for serious entrepreneurs
Cacti Oasis · 4★ · 2024-01-10
When I speak with reps from other apps they rave about Klaviyo, but I'm guessing they have not gone through the onboarding process. We were assigned an onboarding specialist, but they don't help you much with the technical stuff. She's just a project manager, essentially who assigns all the tasks to you. Really great sales pitch, but you feel high and dry after you've signed up. Update: Their documentation is really awful.

hands on and helpful team - did an orientation that made it easy to get started with all the things i wanted to implement. and when i was confused about something, they have very helpful ~real humans~ to chat with you and troubleshoot. Marz stayed on the chat with me for an hour and a half and reconnected when i got booted out by my browser a couple times. and at the end sent a full transcript of our chat. love the level of service and accountability.
