Klaviyo: Email Marketing & SMS , 1,980 reviews

This is Email app is so easy to use. You can use their design builder to create stunning email campaign templates.

I have to say I’m not impressed with the customer service. I have had to explain the same issue several times. I sent pictures and a video clip showing my issue and it has still not being resolved. Instead I keep getting people sending me videos of how the same thing. I don’t think I’ll will be moving forward with this app. And I have wasted a lot time trying to set up flows

Love Klaviyo! Easy to use and so so helpful for my business. Would definitely recommend to anyone and it's fantastic no matter your business size.

Honestly, I hate Klaviyo. I was recommended to switch by my Marketing guy (because they get about 50% commission, checkout Klaviyos Gold, Platinum and Silver partner agreements). Its a total ripoff and lacks basic functionality that Mailchimp has. Mailchimp is half the price, with all the same and significantly more features including way better segmentation, demographic estimated, re-marketing tools, postcards, built in surveys, landing pages, etc. Also my favorite Mailchimp feature, is a one-click button that lets you re-send a campaign to those who didn't open it the first time. Gets huge open rate gains. Klaviyo is garbage. I never should have switched over. Don't waste your money.

We switched to Klaviyo for Simone Walsh Jewellery after the Mailchimp break up with Shopify. We couldn't be happier so far. Customer support from Klaviyo has been excellent and we're especially pleased with how detailed we can get with segments and flows (automations) compared to Mailchimp, along with very easy Facebook audiences integration.

In the beginning there was great support. Since a few months the app does not what it suppose to do, sent email reminders to customers.
When I contact the support team all is well according to them. Unfortunatily this is not the case.
I really hope they get things sorted out, otherwise I'm afraid they will lose loads of customers.

Lots of customizations, awesome customer support ;) So far best marketing app that I've ever found ;)

We've recently migrated our large subscriber list from an another ESP over to Klaviyo to use with Shopify. Klaviyo have been super helpful and responsive throughout the whole process, and the migration has been pretty seamless. Live chat have been a great help advising on best practices and tips to improve our deliverability.

Poor support!
something went wrong with my payment while having Campaign starting.
My account was suspended and my campaign+Flows was stopped. For me this is not a professional move how to treat customer and stopping flows and campaigns without any contact!! Also the support did not helped me. I am not able to pay and still waiting for support to help me. Because i can not make payment by my self. This is very very poor. I will move to another email marketing app

1st, extremely expensive. Was paying $80/month for a small list of 3500. I switched to shopify email, which is free and has the same functionality! I now use shopify for all email campaigns and automated flows.

2nd, their billing system is screwed up and they refuse to admit it. When you sign up, they ask for your mailing address, but then automatically copy it over to your billing address without asking. So they ended up charging me incorrectly for sales tax, which they refuse to refund.
