Omnisend Review
The budget Klaviyo with genuine omnichannel chops
Omnisend is the best email marketing tool for small-to-mid Shopify stores that want omnichannel capabilities without Klaviyo's price tag or learning curve. The ability to combine email, SMS, and push notifications in one automation workflow is unique and really useful. The ratings across G2 (4.6), Capterra (4.7), and Shopify (4.8) reflect real daily-use satisfaction. But the deliverability data is a genuine concern — 75.1% overall and 38.7% on Microsoft is below average, and the inconsistency across test rounds suggests this hasn't been reliably fixed. For stores doing under $1M/year with small teams, Omnisend is arguably the best choice. For stores scaling past that, Klaviyo's deeper analytics and more reliable deliverability justify the premium.

Best for
Small-to-mid Shopify stores that want email + SMS + push in one platform without Klaviyo's price tag or learning curve
Not for
Stores with heavy Outlook/Hotmail customer bases (38.7% Microsoft deliverability), B2B businesses, enterprise operations at 50K+ contacts, or advanced marketers who need Klaviyo-level segmentation depth
Omnisend — The Full Picture
Omnisend has carved out a compelling position in the ecommerce email market: it is the tool you choose when you want Klaviyo-like omnichannel capabilities without Klaviyo-like pricing. With email, SMS, and web push notifications unified in a single automation workflow builder, Omnisend offers something that most competitors — including Drip, AWeber, and MailerLite — simply cannot match. G2 rates it 4.6/5 from 1,163 reviews with 75% five-star ratings. Capterra gives it 4.7/5 from 834 reviews with Customer Service at an impressive 4.7. The Shopify App Store score of 4.7-4.8 from over 2,800 reviews confirms that Shopify store owners love this tool.
The elephant in the room is deliverability. EmailToolTester measured Omnisend at just 75.1% overall, with Microsoft/Outlook inbox placement at a dismal 38.7%. That means nearly two-thirds of your emails to Outlook and Hotmail addresses are not reaching the inbox. For a platform that otherwise executes well, this is a serious weakness that we cannot gloss over.
Omnisend has been shipping aggressively through 2025 and into 2026 — a full UI refresh, AI subject line generator, product-level revenue reporting, and Forms AI Assistant all landed in the past year. The platform is not standing still. But until the deliverability numbers improve, Omnisend carries a meaningful risk that its competitors do not.
Pricing Breakdown
Omnisend's pricing is structured across three tiers. The Free plan supports 250 contacts with 500 emails per month, 60 SMS credits, and access to all features — the catch is Omnisend branding on your emails. The Standard plan prices by contact count with a send limit of 12x your contacts: 500 contacts at $16/mo, 2,500 at $44/mo, 5,000 at $81/mo, 10,000 at $132/mo, 25,000 at $282/mo, and 50,000 at $413/mo. The Pro plan adds unlimited email sends and SMS credits equal to your plan price: 2,500 contacts at $59/mo, 10,000 at $150/mo, and 50,000 at $715/mo.
The Klaviyo comparison is where Omnisend's pricing story gets interesting. At 10,000 contacts, Omnisend Standard costs $132/mo versus Klaviyo at $150/mo — a modest gap. At 50,000 contacts, Omnisend Standard is $413/mo versus Klaviyo at $720/mo — that is 42% cheaper, saving over $3,600 per year.
The billing gotcha you need to know: "billable contacts" includes non-subscribers. Abandoned cart contacts, imported contacts, and anyone Omnisend can identify counts toward your billing tier — not just people who opted in. Multiple users report being surprised when their billable count exceeds their subscriber count.
Check Current PricingDoes Omnisend Reach the Inbox?
Omnisend's deliverability is its most significant weakness, and we will be direct about it. EmailToolTester measured overall deliverability at 75.1% in January 2024, placing Omnisend in the bottom third of tested providers. The breakdown by provider reveals where the damage is concentrated.
Gmail performs well at 94%. Yahoo and AOL are both excellent at 100%. The problem is Microsoft — Outlook and Hotmail inbox placement was measured at just 38.7%. That is not a rounding error. It means that for every 10 emails you send to Outlook addresses, roughly 6 are going to spam or being blocked entirely.
Historically, Omnisend's deliverability has bounced between 67.6% and 87.9%, making it one of the most inconsistent platforms in testing. A 20-point range across testing periods suggests infrastructure-level variability rather than a stable sending reputation.
In practical terms, Omnisend works well for stores whose customers are predominantly on Gmail — which, for younger-skewing DTC brands, is often the case. But we cannot recommend Omnisend without flagging this issue. Before committing, check your customer email domain distribution. If more than 15-20% of your list is on Microsoft domains, factor this deliverability gap into your decision seriously.
Automation & Features
Omnisend's automation builder is where the platform actually differentiates itself. It is the only tool in this price range that lets you combine email, SMS, and web push notifications within a single visual workflow. You do not need to build separate automations for each channel — one workflow can send an abandoned cart email, follow up with an SMS 4 hours later, and trigger a push notification the next day.
The platform ships with 27 pre-built ecommerce automation workflows covering the essentials: welcome series, abandoned cart, order confirmation, shipping updates, cross-sell, win-back, and browse abandonment. Setup is fast — users consistently report getting their first automations live within hours, not days.
Ecommerce-specific features are baked in throughout. Product picker blocks pull items directly from your store. Discount code blocks generate unique codes automatically. The gamified Wheel of Fortune signup form is a standout feature that consistently drives higher opt-in rates than standard popups.
The AI Subject Line Generator, launched in March 2025 with built-in A/B testing, is a useful addition. Product-level revenue reporting, added in December 2025, gives you granular attribution data showing which products are being driven by which automations.
Detailed Scores
What We Like
- Only platform with true omnichannel automation — email, SMS, and web push notifications combined in a single workflow builder. Competitors treat SMS as a separate module; Omnisend integrates it natively
- 30-40% cheaper than Klaviyo at every subscriber tier. At 50,000 contacts: Omnisend Standard $413/mo vs Klaviyo $720/mo — saves over $3,600/year
- G2: 4.6/5 from 1,163 reviews. Capterra: 4.7/5 from 834 reviews with Customer Service rated 4.7/5. These are the highest review platform ratings of any tool we cover
- 27 pre-built ecommerce automation workflows — abandoned cart, welcome series, browse abandonment, order confirmation, win-back — that get stores generating revenue within days, not weeks
- 24/7 live chat support with median response time under 4 minutes. Consistently praised across every review platform
- Shopify App Store rating of 4.7-4.8/5 from 2,800+ reviews — the deepest Shopify reviews of any email tool, suggesting genuine daily-use satisfaction
What Could Be Better
- Deliverability tested at 75.1% overall in independent testing (EmailToolTester, Jan 2024) — bottom third of tested platforms. Microsoft/Outlook inbox placement at 38.7% is poor and concerning for stores with Outlook-heavy customer bases
- Historical deliverability is inconsistent — bouncing between 67.6% and 87.9% across test rounds. This unreliability is arguably worse than a consistently low score
- 'Billable contacts' includes non-subscribers: abandoned cart contacts, customers who purchased without subscribing, and imported contacts. This catches users off guard and erodes the pricing advantage over Klaviyo
- Scalability ceiling acknowledged by multiple reviewers — analytics lack enterprise depth, and performance reportedly degrades above 50K contacts. If you are growing fast, you may outgrow it
- Template library (~200) is smaller than Mailchimp (260+) or MailerLite. Design flexibility is limited for brands that prioritise creative control
- AI capabilities lag behind Klaviyo — Omnisend added AI subject lines in March 2025, but Klaviyo offers AI product recommendations, predictive analytics, and churn scoring that Omnisend lacks
What Real Users Say
Omnisend enjoys the strongest community sentiment of any mid-tier ecommerce email platform we have researched. The numbers speak clearly: G2 at 4.6/5 from 1,163 reviews with 75% five-star ratings, Capterra at 4.7/5 from 834 reviews, and a Shopify App Store score of 4.7-4.8 from over 2,800 reviews. These are not inflated scores from a small sample — the volume of reviews gives them statistical weight.
Trustpilot tells a slightly more nuanced story at 4.4/5 from 467 reviews. The 12% one-star rate surfaces real complaints. The most common grievances: the "billable contacts" definition catching users off guard, Pro plan users describing the platform as "very buggy" with inconsistent support quality at higher tiers, and data accuracy concerns around order attribution.
Reddit and ecommerce communities generally recommend Omnisend as the go-to Klaviyo alternative for budget-conscious stores. The sentiment pattern is consistent: users praise the omnichannel workflow builder, the pricing versus Klaviyo, and the speed of getting results.
Support gets strong marks overall. Omnisend offers 24/7 live chat with a median response time under 4 minutes. That is faster than most platforms, and the around-the-clock availability is a genuine competitive advantage for global sellers.
Who Should Use Omnisend
Omnisend is built for one scenario, and it executes that scenario well: small-to-mid Shopify stores that want email, SMS, and push notifications in a single platform without paying Klaviyo prices. If your store does between $50K and $2M in annual revenue and you want omnichannel marketing automation that a solo operator or small team can manage, Omnisend is our top recommendation in this price range.
Budget-conscious Klaviyo users are the other core audience. At 50,000 contacts, Omnisend Standard saves you over $300/mo versus Klaviyo. If you are using Klaviyo but not using its advanced predictive analytics, you are overpaying for features you do not use.
Solo operators and small teams benefit from Omnisend's fast time-to-value. The 27 pre-built workflows, intuitive builder, and strong Shopify integration mean you can have professional automated flows running within a day. The 24/7 support with sub-4-minute response times provides a safety net that matters when you do not have an in-house email specialist.
WooCommerce and BigCommerce stores are also well-served, though the integration depth is strongest on Shopify.
Who Should Skip Omnisend
Do not choose Omnisend if your customer base has a significant Microsoft/Outlook presence. With 38.7% inbox placement on Outlook, you are losing the majority of emails to those addresses. If more than 15-20% of your list sits on Outlook or Hotmail domains, this is a dealbreaker. Look at Klaviyo, ActiveCampaign, or Drip instead.
Avoid Omnisend for B2B email marketing. The platform is built entirely around ecommerce workflows, product-based segmentation, and consumer purchase behaviour. B2B use cases — lead nurturing, account-based marketing, CRM integration — are not supported. ActiveCampaign is the right tool for B2B.
Do not choose Omnisend if you are at enterprise scale with 50K+ contacts. Users report scalability issues at higher contact counts, and the Pro plan at 50,000 contacts costs $715/mo — at which point Klaviyo's deeper analytics justify the premium.
Content creators, newsletter operators, and non-ecommerce businesses should look elsewhere. Omnisend's entire feature set assumes you are selling physical products through an online store. Kit serves creators better. MailerLite serves general-purpose senders better.
Finally, if you are a data-driven marketer who wants Klaviyo-depth segmentation and predictive analytics, Omnisend is not a substitute. It is cheaper for a reason.
How Omnisend Compares
Omnisend versus Klaviyo is the comparison every Shopify store owner eventually makes, and the answer depends entirely on your scale and sophistication.
On pricing, Omnisend wins at every tier. Standard plan at 10,000 contacts: $132/mo versus Klaviyo at $150/mo. At 50,000 contacts: $413/mo versus $720/mo. The gap is modest at lower tiers and dramatic at higher ones.
On omnichannel capability, Omnisend matches Klaviyo's core offering. Both provide email plus SMS plus push in unified workflows. Omnisend's implementation is arguably more intuitive for small teams.
On analytics and data, Klaviyo wins convincingly. Predictive analytics, RFM analysis, benchmark data, and deeper segmentation give Klaviyo a significant edge for data-driven marketers.
On deliverability, Klaviyo has the edge. Omnisend's 75.1% overall and 38.7% Microsoft placement lag behind.
On support, Omnisend wins. 24/7 live chat with sub-4-minute response times versus Klaviyo's email-first support. Our verdict: Omnisend is the right choice for stores under $2M revenue that want omnichannel at a fair price. Klaviyo is worth the premium above $2M or if your customer base includes significant Microsoft email users.
