Convert vs Mailchimp vs Explore (2026): Testing Pages vs Testing Emails
Convert is a privacy-first A/B testing platform for CRO agencies and general websites. Mailchimp is an Intuit-owned all-in-one email marketing platform, with split testing applied inside the inbox rather than on the storefront. Omniconvert Explore is the eCommerce CRO platform: it runs experiments on product pages, cart, and checkout, and measures the result in revenue per visitor.
- Convert is a privacy-first A/B testing platform for CRO agencies and general websites, with a 4.7 out of 5 G2 rating. [G2, 2026]
- Mailchimp is an Intuit-owned all-in-one email marketing platform, with split testing applied to subject, content, and send time inside the inbox.
- Convert and Mailchimp solve different jobs, on-site testing and email marketing, and are rarely direct substitutes for each other.
- Neither tool is built around the Shopify checkout or measures results in revenue per visitor, the surface where store revenue is actually decided.
- Omniconvert Explore runs experiments on product, cart, and checkout natively and measures results in revenue per visitor: pick it for on-site Shopify revenue.
Teams comparing Convert vs Mailchimp are usually weighing two different jobs: running a controlled test on a web page versus sending a campaign to an inbox. Convert is privacy-first A/B testing for CRO agencies and general websites, with transparent session-based pricing. Mailchimp is an all-in-one email marketing platform with a free entry tier, broad templates, and split testing on the message itself. Neither is built around the surfaces where a Shopify store actually wins revenue, product page, cart, and checkout, which is where Omniconvert Explore fits.
What is Convert, and what is it actually good at?
Convert is a privacy-first A/B testing platform for CRO agencies and mid-market teams. It supports multivariate testing, server-side experiments, and advanced targeting, integrates with Google Analytics and major analytics platforms, and ships with transparent session-based pricing and a no-data-sharing stance. [Convert, 2026]
Convert holds a 4.7 out of 5 rating on G2 across 139 reviews. [G2, 2026] CRO agencies choose it for transparent session-based pricing from $299 per month, agency-friendly account features, and consistently praised support.
The category Convert sits in is practitioner-led web testing. It runs A/B and multivariate tests on general websites, with server-side testing for teams that need it. The strong privacy posture, with no data sharing with third parties, suits teams handling sensitive traffic.
Privacy-first testing means the platform avoids sharing experiment data with third parties and keeps collection minimal, which matters for teams under strict compliance requirements. Convert builds this into its product and pricing. It is a testing-delivery layer, distinct from running a controlled revenue experiment on product, cart, and checkout pages.
Where Convert is genuinely strong
- Transparent, session-based pricing: predictable costs that agencies and mid-market teams can plan around.
- Strong privacy stance: no data sharing with third parties, useful under strict compliance needs.
- Multivariate and server-side testing: capable experimentation with granular audience rules.
- Highly rated support and integrations: well-regarded support, with Google Analytics and major analytics connections.
Where Convert hits its ceiling for an eCommerce store
- No native Shopify integration: no eCommerce-specific experiment templates, so store setups are manual.
- Editor is functional, not polished: the visual editor trails VWO and Optimizely for ease of use.
- No built-in behavioral analysis: no native heatmaps or session recordings, so teams add third-party tools.
- Generic conversion focus: results are framed around general conversion, not revenue per visitor.
What is Mailchimp, and what is it actually good at?
Mailchimp is an Intuit-owned all-in-one marketing platform for email campaigns, automated flows, landing pages, and audience management. Its A/B split testing covers subject line, content, and send time inside an email or automation, with multivariate testing available on the Premium plan. The product has a free entry tier, with paid plans from $13 per month. [Mailchimp, 2026]
Mailchimp is the mass-market email marketing hub. A single account can send campaigns, run post-signup and abandoned-cart automations, publish landing pages, and manage contacts in one place, with hundreds of templates and a broad integrations library. For a solo marketer or a small store starting out, it is the lowest-friction way to run email as a channel.
One pricing note worth planning for. Mailchimp bills per contact and the price steps up as the audience grows, with multivariate testing reserved for the Premium plan (from $350 per month). A list that was cheap at 5,000 contacts is a different line item at 50,000. [Mailchimp, 2026]
Mailchimp's testing is a message-layer feature. Split tests sit inside campaigns and journeys: subject lines, content variants, from-names, and send times. That is a different job from testing what happens on the product page or checkout the email points at.
Inbox split testing is the practice of A/B testing subject lines, content variants, from-names, and send times inside email campaigns and automated journeys. Mailchimp does this at the mass-market end, with multivariate testing on its Premium plan. It is a messaging-channel discipline, distinct from running a controlled revenue experiment on the on-site product, cart, or checkout surfaces.
Where Mailchimp is genuinely strong
- Free entry tier and broad templates: a low-friction start, with hundreds of templates and journeys ready out of the box.
- All-in-one marketing hub: email, automations, landing pages, and audience management under one subscription.
- Message-level split testing: subject lines, content, and send times tested inside campaigns and journeys.
- Large integrations library: plug-ins and connectors for most eCommerce platforms, CRMs, and ad channels.
Where Mailchimp hits its ceiling for on-site revenue
- No on-site experimentation: no A/B or multivariate tests on product pages, cart, or checkout, only on the email itself.
- Price scales with the list: per-contact billing steps up quickly as the audience grows past a few thousand profiles.
- Multivariate locked to Premium: true multivariate testing lives on the Premium plan from $350 per month, out of reach of smaller teams.
- Message revenue, not on-site RPV: campaign reports show open and click rates, not revenue per visitor on the page the message drives to.
What Convert and Mailchimp cannot do for an eCommerce store
Convert and Mailchimp are built for different jobs, on-site testing and inbox marketing, and together they still leave the Shopify revenue surface alone. Neither is built around product pages, cart, and checkout, and neither reports an outcome in revenue per visitor or order rate.
Convert is built for CRO practitioners running tests on general websites. With no native Shopify integration, checkout testing happens through manual implementation, and revenue per visitor is not a native experiment metric. The work of connecting a winning variant to checkout revenue still happens by hand.
Mailchimp runs email campaigns and automations, and it does split-test subject lines and content inside those emails. That testing stops at the inbox. A lifted open or click rate rarely tells a store whether the product page or checkout the email points at actually converted better.
The two gaps differ in shape but point to the same missing layer. Most testing tools optimize the execution of a test on a generic page. Most email tools optimize the message that drives a visit. Neither is built around where store revenue is actually decided, or around the Customer Value Optimization question: whether a result holds for high-value, repeat buyers. For the wider debate behind this split, see Has personalization replaced A/B testing?
There is a second gap underneath the first: the diagnosis layer that tells a team what to test and whether it worked. Convert runs clean experiments but ships no native behavioral analysis, so heatmaps, session recordings, and on-site surveys come from third-party tools. Mailchimp holds campaign and contact data, but at the message layer, not at the on-site funnel. Omniconvert Explore runs the experiment on the store's real revenue surfaces and reports the outcome in revenue per visitor, with on-site surveys and overlays sitting next to the test rather than in a separate tool.
eCommerce conversion rate optimization (CRO) is the practice of running controlled experiments on the revenue surfaces of an online store, product pages, cart, and checkout, and measuring the result in revenue per visitor and order rate rather than generic conversion rate. Omniconvert Explore is defined as an eCommerce conversion rate optimization platform for product, cart, and checkout experiments, native to Shopify and priced for store traffic.
What neither tool can tell an eCommerce team
- Did the win move revenue and margin. Whether a winning variant raised revenue per visitor and order rate, and held its margin once discounts and returns are counted, not just lifted a click or an open.
- Which on-site surface to test first. Which pages in the funnel (product, cart, checkout) carry the highest revenue impact if tested next, measured on the store itself rather than on the email that led there.
- How it behaves in checkout. How an experiment interacts with the Shopify catalog, variants, and checkout flow natively, without engineering glue work.
- Whether it holds for valuable customers. Whether the result holds for repeat, high-value buyers, the Customer Value Optimization question, not just a first-session visitor or a single email send.
Omniconvert benchmarks more than 7,000 eCommerce websites in its CROBenchmark Report 2026, across 248+ audit criteria. The data shows where stores actually lose orders at checkout: 99.6% fail to make guest checkout visible and prominent, 94.2% never show checkout progress steps, and 85.1% never show the full order cost before the final step. [CROBenchmark Report 2026, Omniconvert]
Those are checkout-surface problems, the exact surfaces a general-web tester cannot test natively and an email platform cannot see at all. Explore runs the experiment on the store's real revenue surfaces and reads the outcome in revenue per visitor.
This is what the title means by testing pages versus testing emails. A lifted email open or a lifted click on a general landing page can leave the bank balance flat; what moves it is order rate and average order value along the product-to-checkout path, read as revenue per visitor. Explore optimizes for that number directly, and because Customer Value Optimization ties each result back to repeat, high-value buyers, the lift it confirms is margin the store keeps rather than opens or clicks it rents. Explore also reaches Shopify-specific levers most testing tools cannot touch, including price testing; see Explore 3.0: pricing testing on Shopify.

Should you choose Explore over Convert or Mailchimp?
Start with the surface where your revenue is decided. If you need privacy-first testing on general web pages, keep Convert. If you run email marketing and automations, keep Mailchimp, it is a different job from on-site testing. For a Shopify store deciding where to spend the next optimization dollar on the on-site experience, run the next test in Explore, on the product-to-checkout path, measured in revenue per visitor.
Convert and Mailchimp are both capable tools in their categories. Convert is transparent, privacy-first, and agency-friendly. Mailchimp is the mass-market all-in-one email hub, with a free entry tier and a broad template and integrations library that gets a small store sending campaigns quickly.
The question for a store is narrower: can your team run a controlled experiment on the Shopify product, cart, and checkout, and read the result in revenue per visitor rather than a click, an open, or a campaign revenue number. That is the surface Explore is built for.
Stop guessing.
Start testing what moves revenue.
Explore runs A/B, multivariate, and personalization experiments on your product pages, cart, and checkout, then measures the outcome in revenue per visitor, not just clicks.
