Pros & cons
Klaviyo
Pros
- Best-in-class Shopify-native integration
- Segmentation depth nothing else matches at this price tier
- Predictive analytics that earn back their cost past $50k MRR
- Reliable deliverability with shared and dedicated IPs
Cons
- Pricing scales aggressively past 50k contacts
- Email builder still feels dated next to Postscript / Omnisend
- Onboarding requires real lift — not a "set it and forget it" tool
Omnisend
Pros
- Best price-to-feature ratio in the email category
- Pre-built ecom automations save weeks of setup
- SMS in the same dashboard, not a bolt-on
Cons
- Segmentation depth a step behind Klaviyo
- Customer support response time variable
- Integration ecosystem narrower outside ecom
Our verdict
Under $50k MRR: Omnisend, every time. Past $50k MRR with real segmentation needs: Klaviyo earns its premium.
