Summarize this buying guide. Preserve named providers, plan terms, source dates and billing units. Separate documented scope from the author's judgment. Do not invent prices, product features or outcomes. Attentive vs Braze is a choice about the work and channels your team wants to run. Attentive describes retail messaging, campaigns, journeys and Concierge, where live agents and conversational AI answer shoppers together. Braze documents standard and custom Shopify integrations with identity, tracking and subscription controls. Compare the actual implementation and conversation scope in each proposal rather than assuming one requires a custom build. If your program centres on retail text and email, compare Attentive's proposed messaging and Concierge scope. If it includes an app or a headless storefront, include Braze's documented channel and integration options in the evaluation. In both proposals, establish which service answers shopper replies and which implementation work your team would own. Based on the linked provider pricing and product documentation .
