Pricing comparison
What users say
HubSpot Marketing Hub
What users love
- One platform for marketing automation plus CRM removes integration overhead
- Mature integration ecosystem with 1,500+ apps in HubSpot Marketplace
- Per-contact pricing tiers from free through enterprise predictable as you grow

- Customization is limited for complex multi-brand or non-B2B-SaaS use cases (per G2 reviews)
- Reporting depth is lighter than dedicated BI tools (per G2 reviews)
Klaviyo
What users love
- Native Shopify integration plus pre-built e-commerce flows (abandoned cart, browse-abandonment, post-purchase) ship measurable revenue in days — agencies report $40K+ extra monthly revenue from abandoned cart sequences (per Reddit r/ecommerce)
- Email plus SMS plus RCS plus mobile push plus WhatsApp in one platform — no separate vendor contracts for the long-tail channels
- Permanent free tier (250 profiles, 500 emails/month) supports early DTC brands through MVP and first paying customers
- Strong segmentation and predictive analytics — Sunset Flow plus suppression strategy let stores manage 30K+ contact lists without runaway billing
Common complaints
- Active-profile pricing scales sharply with list growth — stores routinely report bills doubling in 12 months; users at 2K contacts pay ~$60/month, 26K-profile stores pay $2,000+/month for SMS alone (per G2 + Reddit r/ecommerce)
- SMS pricing is brutal at scale — 40K SMS/month with 200K credit burn translates to $2,150/month for a single channel; unused SMS credits do not roll over (per Reddit r/ecommerce + G2 reviews)
- Steep learning curve for advanced flows, segmentation logic, and event triggers — non-technical users hit a wall (per G2 reviews)
- Active-profile billing model penalizes infrequent senders — alternative pricing-by-sends would cut costs ~50% for stores that broadcast monthly or less (per Reddit r/ecommerce)
