The best-value e-commerce email and SMS platform for Shopify, WooCommerce, and BigCommerce stores under $1M revenue.

Omnisend is an e-commerce email and SMS marketing platform built for online stores. Not a general-purpose email tool that happens to support Shopify. It was designed from day one for Shopify, WooCommerce, and BigCommerce merchants who need to convert browsers into buyers without stitching three tools together.

The platform covers email, SMS, web push, and WhatsApp inside one dashboard. No juggling third-party SMS apps. No Zapier glue between channels. One tool, multiple channels, e-commerce native.

Who this is for

Omnisend sits in a specific slot. If you run a Shopify, WooCommerce, or BigCommerce store doing under $1M annual revenue and want email and SMS in one platform without paying Klaviyo prices, you are the buyer. The platform exists to give serious e-commerce stores the tools Klaviyo charges premium for at a price most founders can stomach.

If you publish a newsletter, sell digital courses, or run B2B sales, the math rarely works. The store-centric features (product picker, cart recovery, browse abandonment, order-data segmentation) are the value. Without a Shopify-style store behind it, you are paying for plumbing you cannot use. Newsletter operators should look at ConvertKit or Beehiiv. B2B teams fit better with ActiveCampaign.

The clearest signal you are in the right zone is your current platform invoice and your data sophistication. If you are on Mailchimp and frustrated by weak e-commerce features, switch. If you are on Klaviyo and the monthly bill is painful, Omnisend is worth a serious look. If you need predicted next-order date and lifetime value scoring, stay on Klaviyo. The data depth is not yet matched.

How we tested

We ran Omnisend on the Standard plan ($16/mo, 500 contacts) from March 1 to April 10, 2026, connected to a test Shopify store with roughly 800 historical customers and 1,200 abandoned carts seeded from the prior 90 days. We built a four-channel automation (email at hour 1, SMS at hour 24, web push at day 3, follow-up email at day 5), a browse abandonment flow, a welcome series, and a post-purchase upsell. We sent two campaigns, ran A/B splits on subject lines, and pushed the free SMS credit allowance to its limit.

Scoring follows our six-dimension rubric: features, usability, pricing, support, automation depth, and SMS channel quality. Each score is 0.0 to 5.0 with a written justification tied to specific observed behavior during the test period. The weighted overall rating uses Features 25%, Usability 20%, Pricing 20%, Support 15%, and Automation plus SMS-channel split the remaining 20%. Full methodology at our methodology page.

Feature score deep-dive

The scorecard above is a summary. Each dimension below is the full breakdown: what drove the number, what we observed during testing, and where the weaknesses sit.

Features — 4.3 / 5

Email, SMS, web push, and WhatsApp ship inside one dashboard. The product picker drops live store items into emails with auto-updating images, names, and prices, and pre-built flows (cart, browse, post-purchase, win-back, birthday) activate without a builder marathon. Where it lags Klaviyo is predictive analytics. There is no native predicted next-order date or LTV model, so data-heavy operators still drift to Klaviyo for scoring.

Usability — 4.5 / 5

Connect a Shopify store and Omnisend pulls products, customers, order history, and browsing behavior automatically. During testing we had a cart abandonment flow live and recovering sales inside 30 minutes, no agency required. The drag-and-drop email editor is clean, the automation canvas is readable, and the in-app guidance points first-run users toward the flows that move revenue. Template library is functional but not exceptional.

Pricing — 4.6 / 5

Free plan covers up to 250 contacts with 500 emails per day, 60 SMS per month, and every pre-built automation. No time limit. Standard starts at $16/mo (500 contacts, 6,000 emails/mo) and Pro at $59/mo unlocks unlimited emails, included SMS credits for US/UK/CA, and a custom IP. Versus Klaviyo at $45/mo for the same 500-contact slot, the gap is hard to argue with for stores under $1M revenue. Pricing scales with contact count, so model your list growth before committing.

Support — 3.8 / 5

Free users get limited support, mostly self-serve docs and community. Paid plans get 24/7 email and chat with response times that ranged from under one hour to roughly six hours during testing, no priority tiering visible until Pro. Documentation is solid for the common e-commerce flows but thinner on advanced segmentation and deliverability tuning. Pro plan customers report faster turnaround, which matches the marketing.

Automation depth — 4.4 / 5

Welcome series, abandoned cart, browse abandonment, post-purchase, win-back, and birthday flows are wired and ready. Standard plan adds A/B splits inside automations and conditional branching on engagement, segment, or order data. During testing we built a four-step omnichannel flow (email at hour 1, SMS at hour 24, push at day 3, follow-up email at day 5) without leaving the canvas. The weak spot is custom event triggers for non-store data, which require workarounds.

SMS channel — 4.2 / 5

SMS lives in the same builder as email and pulls from the same contact list, no third-party app, no Zapier. Pro plan includes free SMS credits for US, UK, and Canadian numbers each month. After credits, US messages run roughly $0.015 each, which adds up fast on high-frequency campaigns. The compliance flow (opt-in capture, STOP handling, sender ID) is built in. International rates vary by country, so price-check your top markets before scaling.

Pricing breakdown in practice

Headline pricing does not tell the full story. The two variables that move real cost on Omnisend are (1) contact count, which scales the plan fee on Standard and Pro, and (2) SMS volume, where included credits cap fast and per-message rates kick in.

On the Free plan you get up to 250 contacts, 500 emails per day, 60 SMS per month, and every pre-built automation. That is enough to run a brand-new store without paying. Standard at $16/mo opens the 500-contact slot with 6,000 emails per month, A/B splits, and conditional branching. Pro at $59/mo unlocks unlimited emails, included SMS credits for US/UK/CA, advanced reporting, and a custom IP. The Standard tier covers most stores under $1M revenue. Pro is for high-frequency senders with serious SMS volume.

All figures verified against the current Omnisend pricing page.

Automation depth and pre-built flows

The pre-built flow library is the spine of the platform. During testing we activated five flows in one afternoon: welcome series, abandoned cart, browse abandonment, post-purchase upsell, and win-back. Each one ships with sensible delays, conditions, and copy you can rewrite in the editor. The product picker pulls live store items into the email, so the recommendation block stays current as your catalog changes.

The automation canvas handles multi-step logic with branching, time delays, conditional waits on engagement or segment data, and channel mixing in one flow. We built a cart sequence that fires email at hour 1, SMS at hour 24 if no purchase, web push at day 3, and a follow-up email at day 5. It ran cleanly. Where the builder lags is custom event triggers for non-store data: if you want to fire on a webhook from a third-party app, you need workarounds via Zapier or the public API.

SMS as a native channel

SMS is built into the same dashboard as email and shares the same contact list, the same segments, and the same automation canvas. No third-party app, no Zapier glue, no separate compliance dashboard. Opt-in capture, STOP handling, and sender ID configuration are wired into the platform. This matters because most competitors that claim SMS support either bolt it on through a partner (Twilio fees on top) or require a separate workflow.

The economic story is mixed. Pro plan ($59/mo) ships with included SMS credits for US, UK, and Canadian numbers each month, which is genuinely useful for moderate volume. After credits exhaust, US messages run roughly $0.015 each. A weekly campaign to a 10,000-contact US list runs $150 per send, or $600 per month, on top of the plan fee. Heavy SMS senders should model the math before assuming the plan price is the whole story.

Switched from Klaviyo and cut our monthly bill by 40% without losing the flows. SMS in the same dashboard means one less tool to maintain.

Versus Klaviyo, Mailchimp, and Drip

Klaviyo is the obvious comparison. It wins on predictive analytics (predicted next-order date, predicted LTV, churn risk) and on data depth at higher revenue tiers. Stores doing $5M+ usually stay on Klaviyo because the segmentation engine handles complexity Omnisend does not. Below $1M revenue, the price gap (roughly 30 to 50%) and the native multi-channel story tip toward Omnisend.

Mailchimp is not really an e-commerce tool. It is a general-purpose email platform with bolt-on store features. The product picker, cart recovery, and segmentation Omnisend ships natively are weaker or missing in Mailchimp. Mailchimp is fine for newsletters and general marketing. For a Shopify store, it is a downgrade.

Drip targets the same e-commerce slot as Omnisend but at a higher price ($39/mo entry vs $16/mo) and without the same multi-channel depth. SMS is limited, and there is no free tier. Drip is fine if you specifically need its tagging model. For most stores, Omnisend covers the same ground for less.
