Our verdict
For a Shopify store, Omnisend is the more natural fit: email and SMS in one Shopify-native app, store-built automation (abandoned cart, post-purchase, browse), and a free tier to start. ActiveCampaign wins on raw automation depth and CRM — branching, conditional workflows and lead scoring that go beyond Omnisend — but it's a generalist that connects to Shopify via app/API rather than being built for it, and it scales by contact count (now billing inactive contacts too). Pick Omnisend if Shopify-native email + SMS and a fast free start are the point; pick ActiveCampaign if you need deep cross-channel automation and a CRM and you're willing to wire it into Shopify. For the deepest Shopify retention specifically, Klaviyo remains the benchmark. For the full Omnisend pricing breakdown (billable-contacts denominator + MCP on Free), see /pricing/omnisend.
Related comparisons
- BrevovsOmnisend
For a Shopify store that mails regularly, Omnisend is the better fit: Shopify-native email and SMS in one app, store-built automation, and a free tier aimed at e-commerce. Brevo's edge is its pricing axis — it charges by emails sent, not contacts, so a large list that ships campaigns infrequently pays less than it would on contact-based plans, and SMS/WhatsApp plus a CRM are built in. Brevo's automation is shallower and its free plan has a daily send cap. Pick Omnisend if Shopify-native flows and frequent sending are the point; pick Brevo if you have a large, low-frequency list and send-volume pricing is the decisive saving. For deep retention automation, Klaviyo still outranks both. For the full Omnisend pricing breakdown (billable-contacts denominator + MCP on Free), see /pricing/omnisend.

- ActiveCampaignvsMailchimp
Mailchimp wins the start: a free tier (250 contacts), Essentials at $13/mo, and an interface most operators already know. ActiveCampaign wins the ceiling: branching, conditional automation and a built-in CRM that go far deeper than Mailchimp, from $15 (Starter) / $49 (Plus) / $79 (Pro). Both scale by contact count and both bill harder as you grow — ActiveCampaign now charges for inactive contacts too. For a Shopify store, choose by need: Mailchimp if you want a cheap, familiar start and shallow automation is fine; ActiveCampaign if branching workflows and a CRM are the point and you'll invest the setup time. If Shopify-native flows and SMS are what you actually want, Klaviyo or Omnisend beat both. For the full Mailchimp pricing breakdown (unsubscribed-bloat tax + April 13 hike), see /pricing/mailchimp.
Open
- MailchimpvsOmnisend
For Shopify stores under 2,000 subscribers in 2026, Omnisend is the cleaner pick — free-tier covers more, ecommerce automation is included where Mailchimp gates it to Standard at $20/mo, and Omnisend's ~4-minute average support response (per vendor + corroborated by 4.7/5 ease-of-use on G2) reduces onboarding friction. Mailchimp wins only when an existing audience or brand workflow makes migration costly — and only on the Essentials tier at $13/mo where multi-step automation is not needed. For brands above 2,000 subscribers, this comparison reshapes around Klaviyo entering the picture. For the full Mailchimp pricing breakdown (unsubscribed-bloat tax + April 13 hike), see /pricing/mailchimp. For the full Omnisend pricing breakdown (billable-contacts denominator + MCP on Free), see /pricing/omnisend.

- KlaviyovsOmnisend
For Shopify stores under 25,000 contacts in 2026, the choice splits on what you're optimizing. Sub-5k stores wanting cheaper math, faster setup, and ChatGPT-style access to store data via Omnisend MCP — pick Omnisend, typically 30–50% lower monthly bill. 5k+ stores that need ecommerce flow depth (browse abandonment, post-purchase product recommendations, predicted CLV), or that already pay for support and would benefit from Klaviyo Customer Agent's email-attributed conversation handling — pick Klaviyo. The April 1, 2026 Customer Agent jump from $140 to $200 doesn't flip the decision — it's a separate $200/mo add-on, not a baseline price bump. Decisive question: do you need behavioral-event-level segmentation? If yes, Klaviyo. If 'good-enough' segmentation plus operator-facing AI via MCP is the priority, Omnisend. For the full Klaviyo pricing breakdown, see /pricing/klaviyo. For the full Omnisend pricing breakdown (billable-contacts denominator + MCP on Free), see /pricing/omnisend.
