Klaviyo has been an excellent addition to our store. The platform is powerful, intuitive, and makes email/SMS automation feel effortless. Segmentation, flows, and reporting are all top‑tier. Support has been responsive and genuinely helpful whenever we’ve needed guidance. Highly recommended for any merchant serious about retention and growth.

We have been using Klaviyo for several years for email marketing and automation in our Shopify store, and overall we are very happy with it. The platform is intuitive and easy to work with, and as a Shopify user I especially like that the structure and interface feel familiar. Even as a small business without a dedicated marketing team, I’m able to create campaigns, segments and automated flows myself. There are lots of possibilities as you get deeper into the platform, and we continue to discover features that can make a real difference for our business. Most recently, we implemented Back in Stock notifications, which has already given us valuable insight into customer demand. Klaviyo is a powerful tool, while still being manageable for a small webshop like ours

Klaviyo takes a lot to learn but once you've learnt then its super easy to draft a campaign, check on your flows, design new emails. Its the best email software I've come across.

Nous utilisons Klaviyo depuis plus de 6 ans pour nos campagnes et flows emails. C'est assez intuitif et des améliorations sont régulièrement faites. Facile de connexion avec Shopify. Et les meetings organisés en présentiel sont tops

Picking up
Klaviyo: Email Marketing & SMS usually gets about 72 reviews a month. It got 97 in the last 30 days. That is +35% against its own 90-day pace. We publish this beside the ranking, never inside it – the order is the rating, and a good month does not change how good an app is.
Work on Klaviyo: Email Marketing & SMS?
Any amount puts this listing above the review-data order, on the board and in Marketing and conversion. Every amount and every click is printed in public. Paying also opens a private page for this listing – that is where the badge for your site, the share card and your deal live. Everything you can do here, including what money cannot buy and how to get this listing corrected or taken down.
Not ready to pay for anything? Take the badge – it shows this listing’s live rank on your own site, it is free, and it always was.
Claiming is free and it shows: the listing turns gold in every list – the same highlight a paid card carries – with a Claimed badge, in the exact place its reviews put it. It also earns the only followed link on this site: a claimed listing that has paid nothing links to its own website dofollow – a paid placement never does, because a link that was paid for is an ad. Claiming moves nothing.
