Best Retargeting Ads Tools for Online Stores (2026)

Adwisely (formerly RetargetApp) is built specifically for the retargeting job most online stores actually need doing: turning browsers and cart abandoners into buyers across Meta, Google and TikTok without forcing the founder to become a media buyer. It plugs into Shopify, BigCommerce and WooCommerce in under 10 minutes, syncs your product catalog daily, and then lets Meta Advantage+ Sales and Google Performance Max do the heavy lifting on audience building and bidding.

What makes it stand out in a retargeting context specifically is the combination of automation and a human safety net. At the $249/month Professional tier you get a real ad manager working on your account — 5 hours on Meta and 5 hours on Google each month — which is essentially unheard of at that price. For stores in the $5k-$50k/month revenue bracket that want retargeting to just work, this is the single most leveraged tool on the list.

The trade-off is control: on the Starter plan almost everything is AI-driven, so if you want to hand-pick audiences and creatives, you will feel boxed in. For solo founders and small teams running retargeting on the side, that is usually a feature, not a bug.

Klaviyo is not a paid-ads tool, but leaving it out of a retargeting list would be malpractice. For most DTC stores, email and SMS retargeting via Klaviyo's flows generates more revenue per dollar than paid retargeting ads do — abandoned cart, browse abandonment, and post-purchase winback flows routinely drive 20-40% of total store revenue.

Where Klaviyo specifically shines for retargeting is its behavioral segmentation engine. You can target "viewed product more than twice in 14 days and did not purchase" and fire a personalized flow with the exact SKU they looked at, plus a dynamic discount. That level of granularity is simply not possible inside Meta or Google.

Klaviyo also syncs audiences into Meta Ads and Google Ads, so your email list doubles as a retargeting audience on paid channels. This makes it the natural foundation layer under any of the paid-ad tools on this list — most ecommerce stacks end up running Klaviyo plus one paid-ads retargeting tool.

Omnisend is the Klaviyo alternative built specifically for small-to-mid Shopify and WooCommerce stores that want the same behavioral retargeting flows without the enterprise pricing. Its pre-built abandoned-cart, browse-abandonment, and product-abandonment automations ship with working templates, so you can have three retargeting flows live in an afternoon.

For retargeting specifically, Omnisend's edge is the combined email + SMS + web-push channel mix inside a single flow. A cart abandoner can get an email at 1 hour, a push notification at 6 hours, and an SMS at 24 hours — no zapiering together separate tools. For stores under $1M/year in revenue, this usually outperforms a pure-email setup for a fraction of Klaviyo's cost at similar list sizes.

Where it falls short is enterprise segmentation. If you want to run 40 overlapping behavioral segments, you will outgrow Omnisend eventually — but that is a problem for later.

Retargeting ads die from creative fatigue faster than any other ad type — you are showing the same ad to the same 5,000 people over and over. AdCreative.ai solves that specific problem by generating dozens of on-brand retargeting creatives in minutes, using AI models trained on high-performing ecommerce ads.

For retargeting use cases, it plugs directly into Meta Ads and Google Ads, auto-generates product-specific retargeting creatives from your Shopify catalog, and scores each creative on a predicted-performance model before you spend a dollar. Stores running dynamic product ads can generate dozens of variants per SKU and A/B test continuously — a workflow that would take a designer days.

It is not a standalone retargeting platform (you still need Meta or Google running the ads), so think of it as the creative layer in a stack — typically paired with Adwisely or a manual media buyer.

Most retargeting tools assume your traffic lives on your Shopify site. For a growing number of online stores, though, the actual customer journey starts on Amazon, Walmart or Instacart — and those buyers need to be retargeted inside the marketplace, not off of it. Perpetua is the category leader for that specific job.

Its AI-driven bidding handles Amazon Sponsored Display retargeting (showing ads to shoppers who viewed but did not buy your product), Sponsored Brands remarketing for past customers, and cross-marketplace retargeting across Amazon, Walmart and Instacart in one dashboard. For brands doing $50k+/month on Amazon, the time savings versus managing Sponsored Display campaigns manually are the main pitch.

It is overkill for pure Shopify stores, and pricing is aimed at serious marketplace sellers rather than hobbyists. But if marketplaces are a real channel for you, nothing else on this list retargets there.

Mailchimp is the tool most founders already have in their stack, which is exactly why it deserves a spot here. Its Customer Journey builder handles abandoned-cart and product-retargeting emails, and — less well-known — its Audience feature can sync into Meta Ads to build lookalike and retargeting audiences without a separate tool.

For a store that is just getting started with retargeting, Mailchimp's integrated ads + email + landing page + automation stack means you can run a basic retargeting funnel without signing up for four separate SaaS products. The cost: its ecommerce triggers and segmentation are noticeably weaker than Klaviyo or Omnisend once you scale.

If you are doing under $10k/month in revenue and already pay for Mailchimp, squeeze its retargeting features first before you add another subscription. If you are past that, Klaviyo or Omnisend will almost certainly outperform it.

It sounds obvious, but Shopify itself is increasingly a retargeting tool — and many store owners forget they are already paying for it. Shopify Audiences (available on Shopify Plus) uses aggregated, privacy-safe data from millions of Shopify stores to build high-intent retargeting audiences that you can push directly to Meta, Google, Pinterest, Snap, TikTok and Criteo.

The pitch is specifically compelling for post-iOS-14 retargeting: because Shopify is acting as a first-party data aggregator across its network, Audiences often outperforms platform-native lookalikes for cold-to-warm retargeting, especially for small stores whose own pixel data is too thin to train algorithms.

For non-Plus stores, the native Shopify Marketing section still handles basics: cart-abandonment emails, Meta audience sync, and Google Smart Shopping retargeting. It is not a replacement for a dedicated tool, but it is a free starting point that most stores underuse.
