What is Omnisend?
Omnisend is an ecommerce-first email and SMS marketing platform. Instead of general email marketing bolted onto a store, it's designed around ecommerce behavior — cart abandonment, browse abandonment, welcome flows, and win-back campaigns that trigger from real store events.
Its standout strength is pre-built automation flows. Popular ecommerce journeys like abandoned cart recovery and post-purchase sequences are templates you can activate in minutes, with a drag-and-drop visual builder for customization.

Pricing

Deliverability was the metric that mattered across our test month, and Omnisend held up: campaigns landed consistently, engagement tracking was accurate against our control sends, and automation journeys triggered on time. The learning curve is real but front-loaded — the first campaign setup takes an afternoon, the twentieth takes minutes.
Who Should Skip It
Skip Omnisend if you send only occasional newsletters — a lightweight free tool covers that job, and you'd be paying for automation machinery you never start. E-commerce teams with tiny lists should also do the math on credits versus revenue; the platform earns its keep at meaningful send volume.

FAQ
Is Omnisend free to use?
Yes — Omnisend has a free plan for up to 250 contacts, including email campaigns and SMS at a lower tier. Paid plans start at $16/month, which is notably cheaper than Klaviyo at similar contact counts.
Is Omnisend better than Klaviyo?
For most small-to-mid ecommerce stores, Omnisend offers better value — most core flows come included at a lower price. Klaviyo wins on advanced segmentation, reporting depth, and its wider ecosystem. Both are excellent; choose Omnisend for price, Klaviyo for power.
Does Omnisend work with Shopify?
Yes, Omnisend has one of the deepest Shopify integrations in the space. It syncs products, orders, and customer data automatically, and its automation flows trigger directly from store events like abandoned carts and purchases.
Omnisend vs Klaviyo for a new Shopify store?
Start with Omnisend’s free tier (500 sends, 500 emails/mo with pop-ups) — it covers the first revenue properly. Graduate to Klaviyo when segmentation depth and predictive analytics become the bottleneck, usually past $20-30k/mo revenue.
How does Omnisend pricing scale?
By contacts, not sends — up to 250 contacts free, then Standard/Premium tiers (~$16-59/mo at small list sizes). SMS is credit-based. The pricing curve is gentler than Klaviyo/Mailchimp at small-to-mid lists.
