Klaviyo vs AWeber

This comparison only makes sense if you're an AWeber user wondering whether to upgrade to a more powerful platform for your online store. The answer: if you run ecommerce, yes. Klaviyo's Shopify integration, revenue attribution, and predictive analytics are built for exactly your needs. But Klaviyo costs significantly more — approximately $150/month at 10,000 contacts versus AWeber's $60/month. If you're not running ecommerce, skip Klaviyo entirely — it's designed for online stores and offers no advantage over cheaper tools for other business types.

Our pick: Klaviyo (7.5/10 vs 6.2/10)

Klaviyo wins 3 out of 6 categories. AWeber is better for: non-technical beginners who value phone support and simplicity above all else, and digital product sellers who want built-in payment processing on landing pages.

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

AWeber

Customer support is consistently rated 4.5/5 on Capterra — 24/7 live chat and phone support (8AM-8PM EST). Phone support is rare in this space and really valuable for non-technical users

Smart Designer auto-generates branded email templates from your website URL — enter your domain and it pulls your colours, fonts, and logo. Clever and really time-saving for small businesses

Web push notifications built in — send browser notifications to re-engage visitors. Most email marketing competitors don't offer this at all

December 2024 price hike eliminated ALL grandfathered pricing and hit users with 50-150% increases. Real examples: users paying $29/month saw bills jump to $70+. One user with fewer than 1,000 subscribers went from legacy rate to $55/month overnight

Trustpilot rating of 2.5/5 with 33% one-star reviews — dominated by the price hike backlash and reports of list deletions in January 2025 shortly after the increase

Deliverability is mediocre — EmailToolTester ranked it 11th of 15 platforms at 83.1%. The claim of 'great deliverability' is outdated. MailerLite (94.41%) and ActiveCampaign (94.2%) significantly outperform it
