In This Review
What Is Omnisend?
Omnisend is an email and SMS marketing platform built specifically for ecommerce. Founded in 2014 (originally as Soundest), it's used by 120,000+ brands and has positioned itself as the affordable-but-capable alternative to Klaviyo.
The core product includes email automation, SMS marketing, push notifications, pop-up forms, and a drag-and-drop email builder — all connected to your Shopify data. Omnisend's pitch is simple: the 5–6 automations that drive 80% of email revenue (abandoned cart, welcome series, post-purchase, browse abandonment, win-back) are available at a significantly lower price than Klaviyo.
Where Omnisend deliberately doesn't compete: predictive analytics, deep segmentation at scale, and the breadth of third-party integrations. These are the features Klaviyo charges its premium for. If you need them, pay for Klaviyo. If you don't, Omnisend handles everything else.
Shopify Integration
Omnisend's Shopify integration is solid, though not as deep as Klaviyo's. The key behaviors are covered well.
Shopify event sync
Captures purchases, cart abandonment, order fulfillment, refunds, and product views. Enough data for all core automations without manual setup.
Contact sync
Customers sync from Shopify with purchase history, tags, and custom properties. Existing customers are immediately available for segmentation.
Product blocks in emails
Drag product blocks into emails — images, prices, and links pull directly from your Shopify catalog. Auto-updates when product details change.
Order confirmation & shipping
Replaces Shopify's default transactional emails with branded versions. Upsell and cross-sell blocks can be added to these high-open-rate emails.
Email Automation Flows
Omnisend includes pre-built templates for every core ecommerce automation. Setup is genuinely faster than Klaviyo — most stores can go live with a full automation suite in under 2 hours.
Abandoned Cart Recovery
Live in 20 min3-email sequence with customizable timing and discount logic. Connects directly to Shopify cart data — shows exact abandoned products in each email automatically.
Welcome Series
Live in 30 min4-email sequence for new subscribers. Brand intro → bestsellers → social proof → first purchase incentive. Pre-built template covers all the basics.
Post-Purchase Follow-up
Live in 20 minThank you + product education → review request → cross-sell recommendation. One of the highest-ROI flows for LTV — often ignored by smaller stores.
Browse Abandonment
Live in 15 minEmails customers who viewed products but didn't add to cart. Lower conversion than cart abandonment but much higher volume.
Win-Back Campaign
Live in 15 minRe-engages customers inactive for 90–180 days. Discount offer or exclusive product drop to pull them back before permanent churn.
SMS Marketing
Omnisend's SMS capability is one of its strongest differentiators. 200+ countries covered — compared to Klaviyo's 22. For brands selling internationally, this is a decisive advantage.
Unified email + SMS flows
One automation can send email first, then SMS if no open — cross-channel coordination without managing two platforms.
SMS compliance
Omnisend handles TCPA, GDPR, and country-specific consent requirements automatically. You don't need to manage opt-in rules per country.
Transactional SMS
Order confirmation, shipping updates, and delivery notifications via SMS — high-engagement messages that drive trust and repeat purchases.
SMS-specific flows
Abandoned cart SMS reminders, back-in-stock alerts, and flash sale notifications. All include auto-unsubscribe management.
Forms & Pop-ups
Omnisend includes a built-in form builder for pop-ups, landing pages, and embedded signup forms. The templates are clean and the display rules (scroll depth, time on page, exit intent, page-specific) are solid.
A/B testing pop-up variants is available on higher plans. The forms sync directly to Omnisend contact lists with segmentation tags, so you can immediately trigger different welcome series based on which form a customer came through. This level of integration is better than most standalone pop-up tools.
Pricing: How Much Does Omnisend Cost?
Omnisend uses contact-based pricing with a generous free tier. The price gap vs Klaviyo is significant and grows as your list scales.

| Standard | From $16/mo | 500+ | 6,000/mo | 60 credits |

Real Limitations to Know Before You Buy
No predictive analytics
Omnisend doesn't offer predicted CLV, churn probability, or next order date. If your marketing strategy relies on predictive data segments, you need Klaviyo. For most stores under $100k/mo, this capability doesn't generate meaningful ROI anyway.
Fewer integrations (130 vs 350+)
If your tech stack includes less common tools — niche loyalty programs, subscription platforms outside Recharge, or custom review apps — check the integration directory before switching. The major Shopify apps are all covered.
Segmentation has a ceiling
Omnisend's segmentation is good for most stores, but complex multi-property segments with behavioral conditions start to feel constrained compared to Klaviyo at scale. Not an issue under 50k contacts; can become limiting above that.
A/B testing is limited on Standard plan
Meaningful campaign A/B testing requires the Pro plan. Subject line testing is available across plans, but content variants and flow split testing need an upgrade.
Final Verdict
Highly Recommended
Best email + SMS platform for stores under $100k/mo
For stores doing under $100k/month in revenue, Omnisend is the clear winner. It delivers the 5–6 automation flows that drive 80% of email revenue, at 40–60% lower cost than Klaviyo, with faster setup and better international SMS coverage.
The lack of predictive analytics and the smaller integration ecosystem are real gaps — but they only matter once you're at a stage where advanced data-driven personalization moves the revenue needle. At that point, migrate to Klaviyo. Until then, Omnisend gives you everything you actually need.
