Updated June 11, 2026. Shopify's marketing and conversion category covers reviews, bundles, upsells, checkout, email marketing and customer acquisition. This page is the broad category hub; the deeper review, loyalty and upsell rankings remain separate pages.

Klaviyo
Klaviyo is the first app to review when lifecycle marketing, segmentation, email and SMS revenue are central to the store's growth model.

Omnisend
Omnisend is a strong alternative for merchants that want email, SMS and automation with a more commerce-focused setup path.

Privy
Privy remains relevant when lead capture, popups and simple email/SMS conversion flows matter more than advanced segmentation.

Judge.me
Judge.me earns a place in the broader conversion category because reviews and star ratings are core trust signals on product pages.

ReConvert
ReConvert is useful when a merchant wants to grow AOV through post-purchase offers and thank-you-page conversion flows.
How to choose a marketing and conversion app
Do not install every conversion app at once. Pick the bottleneck: owned marketing, lead capture, social proof, upsells or retention. Marketing apps often leave public storefront scripts, so they are among the easiest categories for Detectify to classify.
Marketing and conversion app FAQ
Which marketing apps are easiest to detect?
Email capture, review widgets, popups, chat widgets and upsell blocks are usually easier to detect because they need to load in the browser.
Should stores install several conversion apps?
Only when each app solves a distinct bottleneck. Stacking popups, upsells and widgets without a plan can slow the store and confuse shoppers.

Detection note
Email capture, review, popup and upsell apps commonly load storefront scripts, making this one of the most detectable categories.
