Omnisend

Omnisend is the email and SMS marketing platform built specifically for e-commerce merchants, offering the deepest Shopify integration and most generous free tier in the e-commerce marketing space. For online stores that need professional marketing automation without the complexity or cost of enterprise platforms like Klaviyo, Omnisend provides the essential capabilities at a price point that growing stores can sustain.

Shopify integration is first-class, with one-click installation and real-time sync of products, customers, orders, and browsing behavior. This native integration powers pre-built automation workflows that can be activated within minutes: abandoned cart recovery, welcome series, order confirmation, shipping notifications, and post-purchase follow-up.

The free tier is notably generous — up to 250 contacts, 500 emails per month, and 60 SMS messages, with access to all features including automation, segmentation, and reporting. This free plan allows merchants to validate the platform's effectiveness before committing to paid plans.

Multi-channel campaigns combine email, SMS, and push notifications into unified workflows. A single automation can send an abandoned cart email, follow up with an SMS reminder 24 hours later, and send a push notification with a discount code — all triggered by a single cart abandonment event. This coordinated multi-channel approach typically recovers more revenue than email-only campaigns.

Product recommendation blocks use purchase history and browsing behavior to insert personalized product suggestions into emails dynamically. Each recipient sees different recommended products based on their individual shopping patterns, increasing relevance and conversion rates without requiring separate email versions.

Pricing starts at 16 USD per month for up to 500 contacts on the Standard plan. The Pro plan at 59 USD per month adds advanced reporting, SMS credits, and priority support. Omnisend's pricing advantage over Klaviyo is significant at comparable contact levels, making it the more accessible choice for growing stores.
