Klaviyo for Shopify stores doing $50K+/year in revenue. GetResponse for stores under $50K or those also running newsletters. Omnisend if you need SMS tightly integrated with email.
Klaviyo dominates Shopify. It earned that position. But it is not right at every revenue level, and most guides do not say when to switch. This breakdown is structured by revenue stage so you can see when each tool earns its cost and when it is pricing you out of margin you should keep.
The fundamental difference between ecommerce email and general email marketing: ecommerce platforms need behavioral triggers. Abandoned cart, post-purchase, browse abandonment, and winback sequences fire based on what shoppers do in your store, not just what you broadcast to a list. If a platform does not have deep Shopify integration and behavioral event triggers, it does not belong on this list.
Starter Tier: Sub-$50K Revenue
At this stage, your priorities are low cost, fast setup, and getting the core flows live. You need abandoned cart and a welcome series. Advanced segmentation can wait.
Mailchimp (Free / $13+/mo): The Shopify integration works, there is a free tier, and you can get basic automations live quickly. The ceiling is low. Once you need advanced flows or serious segmentation, you will feel the constraints. Most stores outgrow Mailchimp by $30K to $50K in revenue. Treat it as a training tool, not a long-term platform.
Omnisend (Free plan available): Built specifically for ecommerce from the ground up, which means the flows are pre-templated for the use cases you need. SMS, email, and push notifications in one platform. If you already know you want SMS in your channel mix, start here instead of Mailchimp. Better long-term ceiling at a similar entry price. Try Omnisend.
Brevo ($25+/mo): The pricing model is the argument. Brevo charges per email sent, not per contact stored. If you have a large list but send infrequently, Brevo's economics beat contact-based platforms at this stage. Deliverability is solid. Ecommerce feature depth is lower than Klaviyo or Omnisend, but at sub-$50K that trade-off is worth the cost savings.
Growth Tier: $50K to $500K Revenue
At this stage you need proper behavioral segmentation, multi-step post-purchase flows, A/B testing inside automations, and analytics that show revenue per flow, not just open rates.
Klaviyo (Free up to 250 contacts, usage-based pricing): The standard choice for Shopify, and it earned that position. Deep native integration means every Shopify event (product viewed, added to cart, purchased, refunded) is available as a trigger with no setup. Predictive analytics surfaces expected next order date, lifetime value, and churn risk at the contact level. The flow library for abandoned cart, winback, and post-purchase sequences is the most sophisticated in this category. The downside: pricing scales with your list. At 50K+ contacts, Klaviyo gets expensive fast. Factor that into your margin math.
GetResponse ($19+/mo): Not a pure ecommerce play, but if you want email, landing pages, and funnels in one place without paying for three separate subscriptions, GetResponse is the pick. Useful for stores running lead-gen funnels, course upsells, or content side channels alongside their product business. Do not choose it for Shopify integration depth. Choose it if the all-in-one platform economics make sense for your setup. Try GetResponse.
Omnisend (paid plans): If SMS is part of your channel mix, Omnisend handles email, SMS, and push notifications natively at the growth stage, with better Shopify integration than GetResponse and more affordable pricing than Klaviyo at similar list sizes. The abandoned cart and post-purchase flows are solid out of the box.
Scale Tier: $500K+ Revenue
At scale, two things matter differently: deliverability at high send volume, and automation sophistication for subscription or loyalty mechanics. Klaviyo is still the default, but there are cases where other tools fit better.
ActiveCampaign: The strongest automation builder in email. If you are running a subscription business, a loyalty program, or anything where the email logic gets genuinely complex (conditional branching, multi-path sequences, CRM integration), ActiveCampaign handles it better than Klaviyo. Shopify integration exists but is not as native. Best for stores where CRM and customer lifecycle management matter as much as the email sends themselves.
Brevo: The case for Brevo at scale is its pricing model. You pay per email sent, not per contact stored. If you have a large list but send infrequently, or maintain a big suppression list for deliverability, Brevo's economics beat Klaviyo's contact-based billing significantly. Ecommerce feature depth is lower, but for list-heavy businesses with lower send frequency, the trade-off is worth it.
Decision Summary by Revenue Stage
One thing that does not change across tiers: the flows matter more than the platform. A well-built abandoned cart sequence on Mailchimp beats a mediocre one on Klaviyo. Set up the fundamentals (abandoned cart, welcome series, post-purchase, winback) before you spend time evaluating features you will not use for another year.
