Klaviyo learns more about each customer every time they engage. All that data is stored in their profile, so your agent can use it to tailor future experiences.
An agent you can trust. No surprises.
How your agent behaves and responds is up to you. You’re in control.
Your brand voice
Define your agent’s tone, persona, and communication style. Set clear guardrails so every response stays on-brand and in line with your policies.
You set the rules, not us.
Configure how each skill behaves, what triggers an escalation, and how your agent represents your brand. No engineers required.
Hand off to live agents with complete context
When a customer needs help from a real person, your agent routes them to Klaviyo Helpdesk or your existing helpdesk with the full history attached, so there’s no need to start from scratch.
“Klaviyo has always prioritised customer activity. It makes perfect sense that they'd be able to take that data and help marketers and service teams make smarter choices on how to help their customers.”
Emeric Harney, Director of Marketing at Harney & Sons
