Pricing comparison
What users say
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)
Mailchimp
What users love
- Intuitive drag-and-drop email builder — most-cited strength across the 12,950-review G2 corpus, with non-designers shipping campaigns same-day
- Solid deliverability and a strong ready-made template library tailored for SMB and nonprofit segments
- Wide integration ecosystem — 300+ apps including all major e-commerce platforms (Shopify, WooCommerce), CRMs (HubSpot, Pipedrive), and ads
- AI Creative Assistant for design help plus Send Time Optimization included on Standard tier and above (no per-feature surcharge)
Common complaints
- Pricing scales steeply with contact count — list growth from 500 to 10k contacts jumps Essentials from $13 to ~$110/mo (per G2 reviews)
- Unsubscribed contacts still count toward the billing total — a long-running practitioner gripe across G2 and Capterra (per G2 reviews)
- Free plan was downgraded sharply — was 2,500 contacts and 10k emails, now 250 contacts and 500 emails with no automations (per G2 reviews)
- Lower-tier support is slow and generic — live chat support is gated behind the Premium tier (per G2 reviews)
- Two parallel email builders (Legacy and New) create navigation inconsistencies and template-portability friction (per G2 reviews)
