Mailchimp vs Omnisend

This comparison matters most for Shopify store owners. Mailchimp lost its native Shopify integration and now requires a third-party connector, which breaks some data sync features. Omnisend was built for ecommerce from day one — native Shopify integration, abandoned cart workflows, product recommendation blocks, and true omnichannel automation combining email, SMS, and push notifications in a single flow. At 10,000 contacts, Omnisend Standard costs approximately $105/month versus Mailchimp Standard at $110/month — comparable pricing but Omnisend includes SMS credits. The only scenario where Mailchimp wins: if you're a non-ecommerce business that needs its 300+ integrations.

Our pick: Omnisend (7.1/10 vs 6.5/10)

Omnisend wins 2 out of 6 categories. Mailchimp is better for: complete beginners who want the easiest interface and maximum third-party integrations.

Pros & Cons

Mailchimp

Genuinely intuitive interface — G2 rates ease of use 4.3/5, Capterra 4.4/5. The drag-and-drop builder has a shallow learning curve for basic campaigns

300+ third-party integrations — the largest ecosystem of any email tool. Nearly every SaaS product connects to Mailchimp natively

260+ professional templates on paid plans. The email builder produces clean, responsive emails that look good on mobile

Free plan has been systematically gutted: 2,000 contacts (pre-2021) → 500 (2023) → 250 (Jan 2026). Automations removed June 2025. A/B testing removed. Email scheduling removed. It is now effectively a demo, not a free plan

Charges for ALL contacts including unsubscribed and bounced — you pay for contacts who will never receive an email unless you manually archive each one. Most competitors only bill for active subscribers

Trustpilot: 2.8/5 with 67% one-star reviews. Support is widely despised — phone support only available on the $350+/month Premium plan. Below that, users report chatbots and generic responses

Omnisend

Only platform with true omnichannel automation — email, SMS, and web push notifications combined in a single workflow builder. Competitors treat SMS as a separate module; Omnisend integrates it natively

30-40% cheaper than Klaviyo at every subscriber tier. At 50,000 contacts: Omnisend Standard $413/mo vs Klaviyo $720/mo — saves over $3,600/year

G2: 4.6/5 from 1,163 reviews. Capterra: 4.7/5 from 834 reviews with Customer Service rated 4.7/5. These are the highest review platform ratings of any tool we cover

Deliverability tested at 75.1% overall in independent testing (EmailToolTester, Jan 2024) — bottom third of tested platforms. Microsoft/Outlook inbox placement at 38.7% is poor and concerning for stores with Outlook-heavy customer bases

Historical deliverability is inconsistent — bouncing between 67.6% and 87.9% across test rounds. This unreliability is arguably worse than a consistently low score

'Billable contacts' includes non-subscribers: abandoned cart contacts, customers who purchased without subscribing, and imported contacts. This catches users off guard and erodes the pricing advantage over Klaviyo
