New revenue stream
Upsell Product Agents to your existing ecommerce clients as a high-impact add-on.
Stronger client retention
Better results for your clients mean stickier relationships for your agency.
Easy to implement
Product Agents connect directly to Klaviyo.
What are Product Agents?
Product Agents plug into Klaviyo and handle product-level email decisions that flows can't – choosing the right product, recipient, and send time for each email based on real-time product and customer behavior. They help clients get more from Klaviyo, and give you a way to deliver Agentic Commerce services with minimal complexity.
Price Drop – Viewed Product
Send 1:1 personalized alerts for products customers viewed.
Price Drop – Alternative Product
Expose shoppers to relevant alternatives on-sale, they may not have considered.
Price Drop – Purchased Replenishment
Prompt faster re-orders when replenishment products go on sale.
Replenishment Reminder
Trigger reminders based on real product usage, not averages.
Recommended Addons
Recommend complementary products that fit exactly with past purchases.
Alternative Picks
Follow up with highly relevant alternatives customers care about, at the right time.
1:1 generated emails
When an agent decides to send, it builds the email for that specific customer and moment:
- Subject line — Written for the individual recipient, based on the product and situation.
- Message text — Explains why this email is being sent, matched to the timing and product.
- Main product — The specific product the agent has decided is most relevant right now.
- Call to action — Links directly to the product, not a generic landing page.
- Supporting products — Included when they add to the main recommendation.
What Product Agents solve
These are some of the most common limitations Product Agents address – things Klaviyo flows can't handle on their own.
Price drops only work on select platforms
Klaviyo's native price drop requires Shopify, Magento 2, WooCommerce, or BigCommerce. Product Agents bring price drop emails to any store on Klaviyo.
Recent buyers get excluded from price drops – even when it makes sense
Standard flows suppress price drop emails after a purchase. But for replenishment products, a recent buyer is exactly who'd want to know. The Price Drop – Purchased Replenishment agent covers this.
Replenishment timing is one-size-fits-all
Most flows apply a single delay to an entire category. Product Agents calculate timing per product, per customer.
Post-purchase recommendations are generic
After the thank-you and review request, most flows go quiet – or fall back on bestseller lists. Product Agents match the next product to what was actually bought, and time it to when the customer is likely ready.
Large catalogs can't be curated manually
Past a few hundred SKUs, hand-picking recommendations doesn't scale. Product Agents map product relationships automatically – no tagging or maintenance needed.
What this means for you
Better results for better client retention
Growing email revenue for clients gets harder once the obvious flows are in place. Product Agents give you a new lever. They work inside the existing Klaviyo setup and generate 1:1 emails that standard flows can't match. When clients see performance improve without a full overhaul, that's a conversation that renews contracts.
Agentic Commerce as your competitive edge
Most Klaviyo agencies compete on the same deliverables – flow builds, template design, campaign management. Product Agents let you bring something different: Agentic Commerce. AI-driven, product-level email decisions that aren't available through Klaviyo alone. That changes how clients compare you to the alternatives.
A service you can sell, not just a product you recommend
Product Agents come with some implementation work: configuring tone of voice, building Klaviyo templates, selecting which agents to activate based on each client's catalog, and optimizing credit usage over time. Setup, strategy, and performance management are all things you already know how to do.
Bonus: A stronger case for Klaviyo migration
If you have clients on other ESPs, Product Agents add another tangible reason to move them to Klaviyo. The migration itself is billable work, and once they're on Klaviyo, you can layer in Product Agents as an immediate next step.
Results from live clients
Early numbers from stores running Product Agents alongside their existing Klaviyo setup.
6x more revenue per email sent compared to standard Klaviyo upsell flows
This makes every email more relevant and work harder than your existing upsell flow — turning post-purchase moments into a powerful revenue channel.
The ideal customer
