Best CRM for integrating with Shopify. Love how products import into email campaigns.

As a beginner I find Klaviyo easy to use and informative, constantly adapting to the ever changing market & trends.

Ran an email campaign for the first time in Klaviyo. As I am new and building the list, even from a small campaign I got 2 conversions in 24 hours. Amazing! Klaviyo made it much simpler to send out the campaign!
— Jyotish Threads
best for service and easy to integrate
— Darajo Supplements
One star. The software is fine. The company is the problem. I run a resale shop. Part of my inventory is published adult art books and Japanese gravure cards. Legal, sold openly on every major marketplace. I sent one campaign that featured an item in that category, not knowing it conflicted with their acceptable use policy. There was no warning. No takedown request. No do that again and we termi...

removed klaviyo because too expensive. Removing it has damaged my code and now shopify team are having to work to fix the problems. Avoid klaviyo like the plague!
— Dr Gus Nutrition
Expensive and impossible to manage effectively.
— Never Enough Cute Stuff
This is not a user friendly app... maybe all email apps are the same. However, the AI 'help' used by Klaviyo runs around in circles and is a step above useless.
— Knead More Fun
its a scam and they put their ugly logo under the mail, ive ss of mails telling me ill be charged and i didnt even use this shitty app
— ahorro.in
The platform functionality might be powerful, but the user experience is incredibly frustrating. When encountering technical issues with dynamic variables in templates, there is absolutely no way to get basic support unless you upgrade to a paid plan. Worse, when trying to log into the Klaviyo Community to post a question, the website gets stuck in an infinite login redirect loop due to cross-dom...

I uninstalled it. A large number of bots from Miami are signing up and creating fake email addresses, and there’s no solution. I even suspect they’re doing this themselves to pressure you into upgrading your plan.
— Tennail
They make it impossible to clear all inactive profiles to susspended. This way they can keep increasing your monthy charge due to profiles. The app is also VERY HARD TO USE. We are an IT company and we find it backwards and HARD. FIND ANOTHER SOLUTION!!!!!! . Klaviyo is outdated and bad

Why merchants pick Klaviyo: Email Marketing & SMS

Klaviyo sits in the retention and lifecycle layer of a Shopify stack, syncing store and customer data to drive segmented email and SMS flows like abandoned cart, welcome, and post-purchase. It is deep and data-rich, but pricing scales with your active profile and SMS volume, so costs grow as your list does — often making it heavier than smaller stores need.
