Omnisend vs Klaviyo Pricing
Free plans compared
| Free plan | Omnisend | Klaviyo |
|---|---|---|
| Contacts | Up to 250 | Up to 250 active profiles |
| Emails per month | 500 | 500 |
| SMS / mobile messages | Not listed on free plan | $5 of mobile messages per month |
| Web push | 500 per month | Not listed |
| Support | 24/7 live chat and email | Email support for the first 60 days |
On the free tier the two are close. Klaviyo’s free plan includes a small mobile messaging allowance, while Omnisend includes web push notifications and keeps 24/7 support on the free plan.
Paid plans
Omnisend: on November 1, 2026, Omnisend’s pricing page showed the Standard plan at $16/month (6,000 emails per month, 500 contacts) and Pro at $59/month (unlimited emails, 2,500 contacts, SMS from $0.007 per message for high-volume US sends), with an introductory 30% discount for the first three months. Prices rise with contact count, so use the calculator on Omnisend’s pricing page.
Klaviyo: Klaviyo’s pricing page uses a plan builder where you choose products (marketing, data and analytics, service, AI agents) and your profile count. Paid pricing is quoted through that builder, so check Klaviyo’s pricing page with your real contact numbers.
How to compare fairly: price both tools at your current list size and at double that size. Contact-based pricing means growth changes the math, and the cheaper tool today might not be the cheaper tool next year.
Omnisend vs Klaviyo for Shopify
Both tools integrate with Shopify and sync customers, orders, and product data so you can build ecommerce automations such as:
- Welcome series for new subscribers
- Abandoned cart and browse abandonment reminders
- Order and shipping confirmations
- Post-purchase follow-ups and review requests
- Win-back campaigns for lapsed customers
- Product recommendations based on behavior
The practical difference is in depth versus speed. Omnisend focuses on getting these core ecommerce flows running quickly with prebuilt workflows. Klaviyo gives you more control over data, segmentation, and reporting, which pays off when you have someone who will use it.

Ease of Use
Omnisend is generally considered easier for small teams. Its editor, prebuilt workflows, and simple plan structure suit store owners who manage marketing themselves.
Klaviyo has a steeper learning curve because it does more. Segments, predictive analytics, and data tools are powerful, but they take time to set up well. If you have a marketer or agency running your email, that depth becomes an advantage.
Support
Omnisend states that it offers 24/7 live chat and email support to all customers on any plan, including free. Klaviyo’s free plan includes email support for the first 60 days, after which free users rely on the help center, community, and training resources; paid tiers unlock fuller support.
If you want help available at any hour without paying more, that is a real point in Omnisend’s favor.
Omnisend vs Klaviyo for SMS
SMS can drive quick sales for ecommerce stores, but it costs more per message than email and needs clear consent.
- Omnisend includes SMS on its Pro plan, with a published starting rate of $0.007 per message for high-volume US sends; the rate varies by country and volume. Global SMS credits can be added to Pro.
- Klaviyo includes $5 of mobile messages per month on its free plan so you can test, with paid usage handled through its plan builder.
If SMS is central to your strategy, request a quote from both based on your expected monthly message volume and the countries you send to.
The First Five Automations to Build (in Either Tool)
Whichever platform you pick, these five flows usually matter most for a store:
- Welcome series: two to four emails that introduce your brand, best sellers, and any first-order offer.
- Abandoned cart: a reminder within hours, then a follow-up the next day.
- Browse abandonment: a gentle nudge to people who viewed products but did not add to cart.
- Post-purchase: order thank-you, care tips or how-to content, then a review request.
- Win-back: a message to customers who have not bought in a few months.
Both Omnisend and Klaviyo offer templates for these, so you do not need to start from a blank page. Get these running and tested before adding more complex campaigns.
