If you're reading this, something specific about Omnisend is bothering you: a price jump, an SMS fee you didn't expect, or a feature ceiling you just hit. Here's the honest rundown of what each real alternative costs on a Shopify store today, what it gives up versus Omnisend, and when the switch is actually worth the rebuild. We make JetFlow, an add-on that generates on-brand campaigns from your store data, so we have a stake in you shipping more email, not in which ESP you pick.
The short version: Klaviyo goes deeper on ecommerce segmentation and predictive analytics, for more money. Brevo includes SMS credits on every plan, including free, where Omnisend reserves SMS for its pricier Pro tier. Shopify Email is free and already sitting in your admin. None of them beat Omnisend across the board, so match the pick to the actual limit you hit.
Why are you actually looking for an Omnisend alternative?
"Omnisend alternative" usually means one of a few different problems. Pick the one that matches you:
- You want SMS without upgrading to Pro. Omnisend keeps SMS off the free and Standard plans entirely. Brevo includes SMS pay-as-you-go credits starting on its free tier.
- You've outgrown Omnisend's segmentation and want predictive sends. Klaviyo's customer lifetime value and churn predictions go further than Omnisend's current toolset.
- You're brand new and don't want to pay for email yet. Shopify Email is free up to 10,000 sends a month and lives in your Shopify admin already.
- The bill grew and you're just price-shopping. Compare the actual numbers below before assuming a swap saves money. It often doesn't.
- Omnisend's automation and AI tools already cover what you need. Then stay. Keep reading for why that's a reasonable call.
Klaviyo: the deepest ecommerce swap
Klaviyo's free plan covers 250 profiles and 500 emails a month, the same contact cap as Omnisend's free tier, plus $5 of Composer (its AI copy and send-time tool) usage at no extra cost. The cheapest paid tier, Email, runs $20 a month for 500 active profiles and 5,000 emails, versus Omnisend's Standard at $16 a month for 500 contacts. So Klaviyo costs more at the entry paid tier, and in exchange you get deeper predictive analytics (lifetime value, churn risk, send-time optimization) than Omnisend currently ships.
On the Shopify App Store, Klaviyo sits at 4.7 stars across roughly 3,440 reviews, just ahead of Omnisend's 4.7 stars across roughly 3,210. Both are mature, Shopify-native tools; the review counts are close enough that track record alone shouldn't decide this for you.

Brevo: the one with SMS actually included
Brevo's free plan is the most generous of the group: up to 100,000 stored contacts and 300 emails a day, with no credit card required. The part that actually solves the Omnisend SMS complaint: SMS is available as pay-as-you-go credits on every plan, including free, rather than gated behind a pricier tier. Paid plans start around $9 a month for 5,000 emails, with unlimited contacts on every paid tier (a real structural difference from Omnisend and Klaviyo, which both price by contact count).
The tradeoff: Brevo's ecommerce-specific triggers (abandoned cart, back-in-stock, price-drop alerts) are real but newer and less deeply built out than Omnisend's or Klaviyo's, since Brevo grew out of general marketing and transactional email rather than ecommerce specifically. If SMS-without-an-upgrade is your actual trigger for leaving, this is the swap that solves it directly.
Shopify Email: free and already in your admin
Shopify Email sends up to 10,000 manual or automated emails a month for free, then $1 per additional 1,000 sends, no separate subscription required. It lives inside Shopify admin under Apps and sales channels, with ready-to-use automation templates (welcome, win-back, upsell) you can customize or extend with custom workflows.
It's genuinely fine for a store sending a handful of campaigns a month. It doesn't attempt Omnisend's web push, multi-channel automation branching, or Klaviyo's segmentation depth. If you're not sure you need a paid ESP at all yet, start here before paying for anything.
What Omnisend still does well
None of this is a case against Omnisend. A few things it does that the alternatives above don't fully match:
- Free web push notifications. Omnisend's free and Standard plans include 500 web push sends a month at no extra cost; none of the three alternatives above offer that on their free tier.
- Ecommerce automation maturity. Omnisend's cart, browse, and order-triggered flows were built around Shopify order data from the start, the same way Klaviyo's were. Brevo and Shopify Email's equivalents are newer or thinner.
- One dashboard for email, SMS, and push once you're on Pro. If you've already paid for Pro, the multichannel view in one place is a real convenience most alternatives split across separate tools or add-ons.
If what's actually bothering you is the price, not the feature set, it's worth checking whether a cheaper Omnisend tier (or just trimming your contact list) solves it before you rebuild everything on a new platform.
Switching ESPs doesn't fix the blank-page problem
Whichever platform you land on, someone still has to write and design every campaign and flow email, on brand, every month. That's the real bottleneck for most one-person marketing teams, and it exists on Omnisend, Klaviyo, Brevo, or anywhere else. JetFlow reads your Shopify store's products, images, and brand colors and generates complete campaigns and flows for you to review, rather than starting from a blank template every time.
To be straightforward about scope: JetFlow exports directly into Klaviyo today. Omnisend is listed as an integration in the works but isn't live yet, so if you're moving off Omnisend, Klaviyo is the one destination where JetFlow removes the blank-page problem immediately rather than down the road. Pricing is $99 a month ($59 billed annually) for the Scale plan or $249 a month ($149 billed annually) for Pro.
