Hectic experience. They hound you until you sign up but then dont respond after you sign up and make the payment. Been dealing with their sales person Sulaiman Lodhi and its our worse experience with an email app to date.

Their customer support team is great! You can get through to them by Live Chat pretty much instantly. Their CS/product teams are knowledgeable and spend time helping you through issues and queries. They've helped me out a lot in the past year!

After subscribing and making payment, I was unable to access my account for two full days. Despite multiple attempts to reach out, their support team offered absolutely no effective solution. Extremely disappointing experience.

My Klaviyo account was hacked, and trying to recover it has been an exhausting experience. I’ve provided every possible piece of verification they asked for — except one email address I’ve never even seen before, which is the whole reason I need help in the first place. Instead of helping resolve the issue, support keeps passing me from one representative to another with no continuity or progress. For a platform that manages customer data and email security, the account recovery process should be far more user-friendly and reliable. This has made me seriously reconsider using Klaviyo at all. As it is, I did not find the app very user friendly or beneficial.

An absolute POWER HOUSE of a platform for emailing, nurture sequencing, customisation to give our customers the EXACT email that converts. Worth every cent and a MUST HAVE for any business. Sure it might seem overwhelming with all of the bells and whistles but learn how to use the entire system they provide properly and it will be one of the biggest reasons your business grows.

Great application with the absolute worst tech support I have ever experienced. Confused about their own product, non-responsive, and basic help takes MONTHS. I have been dealing with an issue since essentially day 1, and it still is not resolved. Expect weeks to go by without a response. Expect to repeat yourself 3-4 times every time your issue is escalated because apparently they don't read notes. Expect the help to not solve the actual issue, and have to repeat the entire process again. If you are not tech savvy and adept and implementing solutions yourself, BUYER BEWARE. You are on your own.
