What it does
B2C CRM and marketing automation for email, SMS, and push, with AI-driven segmentation, flows, and revenue attribution built for ecommerce.
Strong fit
Ecommerce brands (esp. Shopify stores) wanting deep customer-data-driven email/SMS flows, predictive analytics, and revenue attribution in one platform.
Poor fit
Not ideal for B2B sales pipelines or tight budgets with big lists, billing counts every active profile (even unengaged), so costs climb quickly as lists grow.
Limitations
Priced on all active profiles incl. suppressed/cold contacts since the Feb 2025 billing change; plan must match profile count; SMS credits billed separately; learning curve for flows.
Verified facts
Free plan: up to 250 active profiles, 500 email sends/mo, ~$5 SMS credits/mo, basic templates, segmentation, reporting, and Customer Hub/Helpdesk basics.
Priced by active profile count via on-page calculator (default config showed $45 total/mo); email plan widely listed from $20/mo at 251-500 profiles.
