I used Klaviyo for years between 2018-2020 and I was happy with it despite the high costs. More recently they introduced caps on how much you can email before going to the next tier, and their caps are extremely restrictive compared to other ESPs. In order to send 5 emails a week to my entire list costs me double what I'd pay in my tier normally. So for 2000 contacts I'm paying $100/month to send what I want to send. I'm not against a (good) company making money, but their cost is roughly $1 for 10000 sends and they charge you 20x markup just on the sends. This is absolutely ridiculous and their prices don't justify this when you have better and cheaper options available. I'd stay far away from them.

I tried, but really bad experience. Expensive and no help from customer services. Deuces.

ABSOLUTELY HORRIBLE. Do Not Use these guys. Go to MailChimp or whoever else. But def not here! I'd give half a star or zero if I could.

Expensive hidden costs. Unsubscribed and uninstalled a long time ago but they keep sending spammy emails saying 'account limit reached'

Klaviyo's capabilities and its seamless integration with Shopify have made a real difference for my business. I hesitated to switch to it because it was more expensive than what I was using, but it pays for itself and more every month.
Really happy to hear that Klaviyo's been making a difference for your business! Glad that you made the switch, and are seeing success with Klaviyo, and we appreciate the 5 stars!

Klaviyo is hands down one of the most powerful email and SMS platforms available for Shopify. The segmentation, automation, and data depth are best-in-class. When it’s set up properly, it can absolutely drive meaningful revenue. That said, it really shines only if you have someone actively managing it. To get full value, you need consistent flow optimization, campaign strategy, list hygiene, testing, and performance monitoring. It’s not a “set it and forget it” tool, it rewards attention and strategy. I’d also love to see more flexibility in the pricing structure. When performance fluctuates month-to-month, the fixed pricing model can feel slightly disconnected from results. A structure that better reflects engagement or revenue impact would make it even stronger. Overall, it’s still the best tool in the space hands down, just make sure you’re ready to invest the time (or team) to unlock its full potential.
We really appreciate this thoughtful feedback, along with the 5 star review - It's always our goal to empower creators like yourself to feel confident using Klaviyo, and that includes listening to feedback about your experience with our platform and pricing. Thank you again - we're glad you're seeing success with Klaviyo!

Super appli ! Très complet, demande de la pratique pour être à l'aise mais parfait pour gérer petites et grosses campagnes, segmentations, flux.
Merci pour votre avis 5 étoiles ! Nous sommes ravis d'apprendre que vous rencontrez le succès avec Klaviyo !

Klaviyo offers a ton of great features and powerful tools, especially for building flows and creating segments. The in-app designer is stable, intuitive, and easy to work with, and the documentation is clear and helpful when you need guidance. I’ve found the platform overall very easy to use, and I really enjoy the classes — they’re informative and well done. The CSM reps I’ve worked with have also been very helpful.
Thank you so much for the positive review. We always aim to make sure Klaviyo is easy to use and intuitive!

Klaviyo kan åbenlyst en masse ting, men hvis man har unikke domæner tilknyttet sine markeder i Shopify market og har brug for at sende flows og mails ud til kunder i de forskellige markeder så kan man kun gøre det fra et branded mail domain. Det virker besynderligt i 2026 at få besked om at købe 4 x Klaviyo konti, når man har samlet sine markeder i Shopify netop for kun at have 1 webshop. Alternativt foreslog Klaviyo også at jeg kunne få en udvikler til at lave et helt setup. Det så meget indviklede og meget dyrt ud. I øvrigt har jeg fra "Klaviyo" ekspert og selveste Gemini fået at vide at det godt kan lade sig gøre, men det kan det ikke når man så står med problemet og ønsker det løst.
Vi sætter pris på din konstruktive feedback. Et medlem af vores supportteam har kontaktet dig via e-mail og ser frem til at samarbejde med dig om dette problem.

Scammers! I was charged $390 when suppose to be $45 They mislead your in their settings that you wont be charged if you exceed your limit, but you will be so be careful! There conversions metrics are also highly exaugurated. Out of 12 conversions they claim i manage to confirm only 3. Go to other services llike PushOwl, do not use this scammers!

Absolute scammers! BE CAREFUL with this guys! I setup in my Klaviyo settings not to be charged if i exceed my limit of $45 plan. I was assured by their support that i will not and then after just 30 days they were about to charge me more than $600 Thankfully i found out before the charge and canceled the service! Do not trust their settings. They purposly play with words to trick you thinking the "stop" in their settings is for the "profile and email" plan, but its only for the emails and if you exceed that limit you will be charged, in my case a LOT! Scammers, do not trust their support too! btw, they also show you misleading conversions - claiming the conversion is made from Klaviyo when it's clearly from other source and Klaviyo email was not even opened by the customer!
Thank you for the feedback. Klaviyo's profile and email plan charges for both active profiles and emails because Klaviyo exists to help you understand your customers and drive growth through those relationships. If you have profiles that you don't send emails to, we strongly recommend suppressing them. You don't pay for suppressed profiles, but you retain their data so you can understand the actions they took.
