Klaviyo is the best email marketing platform for ecommerce stores where email drives significant revenue. Strengths: deep Shopify integration, predictive analytics (CLV, churn risk), revenue attribution per email/flow, advanced segmentation. Weakness: expensive (2-3x competitors), and Feb 2025 billing change now charges for ALL profiles including unsubscribed. Worth it for stores doing $50K+/month where email is 20-40% of revenue. For smaller stores, Omnisend or MailerLite are better value.
Klaviyo Review 2026: Pricing, Features, and Deliverability for Ecommerce
The Ecommerce Standard
Klaviyo has become the default email platform for Shopify stores. The integration is deeper than any competitor, and the ecommerce-specific features (predictive analytics, revenue attribution, purchase-based segmentation) are genuine differentiators.
The question isn't whether Klaviyo is good. It's whether the premium is worth it for your specific store.
Pricing (March 2026)
| Profiles | Email Only | Email + SMS |
|---|---|---|
| 250 | Free | Free |
| 500 | $20/mo | $35/mo |
| 1,000 | $30/mo | $45/mo |
| 5,000 | $100/mo | $120/mo |
| 10,000 | $150/mo | $175/mo |
| 25,000 | $400/mo | $450/mo |
| 50,000 | $700/mo | $775/mo |
| 100,000 | $1,200/mo | $1,310/mo |
Feb 2025 billing change: Klaviyo now charges for ALL profiles — active, unsubscribed, bounced, suppressed. Clean your list before each billing cycle. A 100K profile list with 30% unsubscribed means you're paying for 30K profiles that don't receive email.
Strengths
Shopify integration depth. Real-time product data sync, browse/cart/checkout events, predicted customer lifetime value, expected next order date, churn risk scoring. No competitor matches this depth.
Revenue attribution. See exactly how much revenue each email, flow, and campaign generated. This data transforms email from "we think it works" to "flow X generated $47K this month."
Pre-built ecommerce flows. 30+ templates: welcome, abandoned cart, browse abandonment, post-purchase, win-back, price drop, back in stock. Each is purpose-built for ecommerce with smart defaults.
Segmentation. Unlimited segment conditions based on purchase behavior, engagement, predicted metrics, custom properties. Create segments like "purchased in last 90 days AND predicted CLV > $200 AND hasn't been emailed in 7 days."
Smart Sending. Automatically suppresses sends to recipients who were recently emailed, preventing fatigue and complaints. Simple feature, measurable deliverability benefit.
Weaknesses
Price. 2-3x more expensive than Omnisend, Mailchimp, or MailerLite at every tier. The premium needs to be justified by revenue impact.
All-profile billing. The Feb 2025 change to charge for all profiles (including unsubscribed) penalizes poor list hygiene. Aggressive suppression list cleaning is now a cost-management necessity, not just a deliverability practice.
Complexity. Klaviyo's segmentation and flow builder are powerful but have a learning curve. Small teams may not use 80% of what they're paying for.
Non-ecommerce use. Klaviyo is built for ecommerce. If you're a SaaS company, service business, or content publisher, you're paying for ecommerce features you'll never use. Use ActiveCampaign or Kit instead.
Deliverability
Klaviyo's deliverability infrastructure is solid:
- Custom domain authentication (SPF, DKIM) supported on all plans
- Smart Sending reduces over-mailing and complaint risk
- Shared IP pools are monitored and maintained
- Dedicated IPs available at high volume (request from support)
- Engagement-based features naturally improve deliverability
Deliverability tip: Klaviyo's Smart Sending and segment-based sending naturally maintain engagement rates. The biggest deliverability risk on Klaviyo is list bloat — since you're now paying for unsubscribed profiles, you might be tempted to keep them. Don't. Suppress and clean aggressively.
Who Should Use Klaviyo
Good fit:
- Shopify stores doing $50K+/month revenue
- Stores where email drives 20-40% of revenue
- Teams that will use predictive analytics and advanced segmentation
- Stores with 5K+ engaged subscribers
Bad fit:
- Stores under $30K/month revenue (ROI hard to justify)
- Non-ecommerce businesses (use ActiveCampaign, HubSpot, Kit)
- Budget-constrained stores (use Omnisend or MailerLite)
- Stores with large inactive lists (billing penalty)
Practitioner note: The #1 Klaviyo cost optimization: suppress unsubscribed and bounced profiles before each billing cycle. A client came to me paying for 80K profiles when only 50K were subscribed. Cleaning saved $200/month immediately — plus improved deliverability since they stopped paying for dead weight.
For a detailed comparison, see our Klaviyo vs Mailchimp and Omnisend vs Klaviyo guides.
Practitioner note: For deliverability specifically: configure custom domain authentication in Klaviyo immediately after setup. Go to Settings → Domains → add your sending domain with DKIM and SPF. This is not optional. Klaviyo emails without custom authentication use Klaviyo's domain, which hurts your DMARC alignment.
If you need Klaviyo configured with optimal deliverability settings and authentication, schedule a consultation.

Frequently Asked Questions
How much does Klaviyo cost in 2026?
Email only: $20/month for 500 profiles, $100/month for 5K, $150/month for 10K, $400/month for 25K, $700/month for 50K. Email + SMS is higher. Important: as of February 2025, Klaviyo charges for ALL profiles including unsubscribed — clean your list aggressively.
Is Klaviyo worth the price?
For ecommerce stores doing $50K+/month where email generates 20-40% of revenue, yes. The revenue attribution, predictive analytics, and advanced flows help you optimize what's working. Below $50K/month revenue, the premium is harder to justify — consider Omnisend or Mailchimp.
What changed with Klaviyo's billing in 2025?
In February 2025, Klaviyo changed billing to count ALL profiles — including unsubscribed, bounced, and suppressed. Previously, you only paid for active/subscribed profiles. This means list hygiene directly affects your monthly cost.
How is Klaviyo's deliverability?
Good. Klaviyo has strong deliverability infrastructure with Smart Sending (auto-suppresses over-mailed contacts), engagement-based features, and custom domain authentication support. Shared IP deliverability is solid. Dedicated IPs available at high volume.
Should I use Klaviyo or Mailchimp for Shopify?
Klaviyo, if you can afford it. Klaviyo was built for ecommerce with deep Shopify integration — real-time data sync, purchase-based segmentation, predicted CLV, and revenue attribution. Mailchimp's Shopify integration is basic by comparison.
