Pros & Cons

Klaviyo

Market-leading ecommerce segmentation with nested conditions, real-time updates, and predicted metrics — no other ESP matches this for Shopify stores

Revenue attribution that shows clear ROI per campaign and per automation flow — users cite this as what justifies the premium price

Deepest Shopify integration available with real-time data sync, product feeds, and browse/cart abandonment triggers

Gets expensive fast: $150/mo at 10K contacts, $400/mo at 25K, $720/mo at 50K, $1,380/mo at 100K — significantly more than every competitor

February 2025 billing change: now charges for ALL active profiles including unengaged subscribers, spam signups, and abandoned checkout contacts. Widely viewed as a post-IPO revenue grab

Trustpilot rating of 2.1/5 — the worst of any tool we reviewed. Support is slow, no phone option, and declining post-IPO as they chase enterprise clients

Omnisend

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

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
