Klaviyo is the most-reviewed email app on Shopify at 3,007 reviews, and it rates 4.7. People do not usually leave because it is bad. They leave because contact-based pricing climbs faster than their revenue does, and because they are paying for segmentation depth they never open.

Selected from Shopify’s own Email Marketing sub-category, so the comparison is like-for-like. The one-line descriptions are each vendor’s App Store tagline, quoted as written.
Omnisend is the closest like-for-like swap, at 4.8 across 2,956 reviews. It covers email and SMS in one app and is the only alternative with review volume in Klaviyo's range.
If flows and segments are genuinely why you use Klaviyo, nothing here replaces it cleanly. If you send campaigns and one abandoned-cart sequence, you are paying for depth you do not touch.
Ranking method, the review floor and how paid placement is kept separate are explained once on how ranking works. Short version: review data sets the order, money never does.
