Boom vs Klaviyo, answered
Is Boom a Klaviyo alternative?
Yes, for teams whose campaigns should turn into conversations. Boom runs journeys on WhatsApp, SMS and email, and its agent starts conversations, calls, hands off to your team and turns every reply into data.
Klaviyo has an AI agent too. What is different?
Klaviyo’s Customer Agent is a support agent. It answers shoppers who write first, with skills for orders, returns, subscriptions and loyalty. Boom’s agent also starts the conversation, makes calls and asks the questions your win-back or research needs.
Does Boom work with Shopify?
Yes. Boom reads customers and orders live from Shopify, as well as from your own database or API, so the agent knows the cart before it writes.
How long does switching take?
Days. Connect Shopify or your data, bring your WhatsApp number and templates, and review the first conversations before going to full volume.
