9 Best AI Automation Tools for Klaviyo in 2026
Klaviyo’s own AI is now very good at Klaviyo. Composer audits your flows, finds the missing revenue, and builds the campaign for you to approve. Customer Agent answers shoppers and completes the return instead of explaining the policy.
What still lands on you is everything after the send. The customer replying to ask if the linen shirt runs small. The boutique that wants wholesale terms. The creator pitching a collab. The Monday numbers your cofounder wants next to Shopify sales. None of that starts in Klaviyo, so none of it reaches Klaviyo’s AI.
Below are nine tools, ranked by how much of that work they take.
TL;DR: Use Composer for campaigns and flows, and Customer Agent for shopper questions. Add Carly for the inbox around them: it reads your mail, holds your calendar, works in Klaviyo and Shopify, and connects to thousands of apps from a plain-language instruction.

1. Carly
Carly is an AI agent with its own email address, connected to Klaviyo, your Gmail or Outlook, your calendar, and the rest of your stack. Email it, CC it, text it, or message it in Slack.
Composer builds the campaign. Carly handles what comes back. A normal week for a two-person brand:
- Campaign replies. A subscriber replies to Thursday’s drop asking if the medium runs small and whether her last order shipped. Carly checks the order in Shopify, answers both questions, and adds a “sizing question” property to her Klaviyo profile so the next campaign can speak to it.
- Wholesale and creator threads. A boutique asks for a line sheet. A creator pitches a collab. Carly replies with your terms, adds them to the right Klaviyo list with source and status, and books the call into an open slot on Google Calendar.
- Pop-up signups. Forward Saturday’s market sheet and every name becomes a Klaviyo profile on the right list, tagged with the event.
- The Monday numbers. Every Monday at 8am, Carly pulls last week’s campaign and flow revenue from Klaviyo, puts it next to Shopify sales in Google Sheets, and emails the three lines that matter to you and your cofounder.
- Supplier slips. A supplier writes that the restock moved a week. Carly flags the launch campaign that depends on it, moves the date on your calendar, and drafts the “coming soon” note for your review.
Ask it “which flows made the most money last month, and which one dropped” and it answers from Klaviyo in a minute.
What makes it different: Composer and Customer Agent both start from Klaviyo data or a shopper on your site. Carly starts from the message in your own inbox and does the work across Klaviyo, Shopify, your calendar, and thousands of apps. It runs the moment mail arrives, so the 2am wholesale enquiry is answered before you open the laptop. You set the rules in plain words, for instance “anyone who replies asking about sizing gets the size guide and a profile tag,” and Carly’s agents run it on every match.
Best for: Founders and small DTC teams whose campaigns are handled but whose inbox is not.
Pricing: Free Zapier-style workflows; AI agents from $35/month
Connect Klaviyo: in Klaviyo, click your organization name in the bottom left, go to Settings > API keys, click Create Private API Key, choose Full access or a custom scope, and paste the key at carlyassistant.com/integrations. You need to be an Owner or Admin, and Klaviyo shows the key only once. Predictable steps, like adding every new wholesale lead to a list or logging campaign revenue to a sheet, run as free Zapier-style workflows. Running several brands or an agency book? Book a call with the Carly team.
2. Klaviyo Composer
Klaviyo’s marketing agent, in public beta since June 2026. It audits your campaigns, flows, and segments, ranks the revenue opportunities, and builds the email and SMS campaign or flow for review. As of September it also runs scheduled audits and saves your brand rules as reusable skills. Nothing goes live without approval.
What makes it different from Carly: the best tool here for building Klaviyo marketing. It works on campaigns and flows, not the replies and wholesale threads in your inbox.
Best for: Finding and fixing underperforming flows, and turning an idea into a ready campaign.
Pricing: Limited free usage on every plan; $20/month for 4x the usage, then $10 per 1,000 credits
3. Klaviyo Customer Agent
A shopper-facing AI agent trained on your storefront, policies, and customer profiles. It answers order status, sizing, and returns questions across web chat, email, SMS, and WhatsApp, completes returns, applies loyalty points, and hands off to a human with context.
What makes it different from Carly: it works the shopper conversation that starts on your channels. Your own inbox, your calendar, and the business-to-business threads are outside its lane.
Best for: Brands that want pre- and post-purchase questions resolved without a human.
Pricing: First 50 AI conversations free, then billed per resolved conversation
4. Claude or ChatGPT with the Klaviyo connector
Klaviyo ships an official connector for Claude and an app for ChatGPT. Ask for a flow audit, a Monday recap, or subject lines shaped by a real segment, and it pulls live Klaviyo data. See Claude + Klaviyo, ChatGPT + Klaviyo, and the Klaviyo MCP server.
What makes it different from Carly: excellent analysis on demand. It acts when you ask or on a schedule you set, so a customer reply landing in your inbox does not start anything.
Best for: Marketers who want ad-hoc reporting and copy drafts from a chat window.
Pricing: From ~$20/month for Claude Pro or ChatGPT Plus
5. Gorgias AI Agent
The helpdesk AI most Shopify brands on Klaviyo already weigh. It answers tickets and takes Shopify actions like refunds, cancellations, and address changes. See the best AI automation tools for Gorgias.
What makes it different from Carly: strong in the support queue, and it overlaps with Customer Agent. Neither touches your own inbox.
Best for: Brands that run support in Gorgias rather than Klaviyo Service.
Pricing: Helpdesk from $10/month; AI Agent add-on from $30/month, billed per automated interaction past the limit
6. Shopify Flow with Sidekick
Free on every Shopify plan, and Sidekick now writes Flows from a sentence. Tag VIPs, flag risky orders, and push customer tags that Klaviyo segments pick up. See the best AI automation tools for Shopify.
What makes it different from Carly: free and native, and it triggers on store events only.
Best for: Store-side rules that feed Klaviyo segments.
Pricing: Included with every Shopify plan
7. Zapier
Connects Klaviyo to thousands of apps with trigger-action Zaps, usually pushing new leads from forms or a CRM into a list.
What makes it different from Carly: unmatched reach, and every Zap is plumbing you define and maintain. See Zapier alternatives.
Best for: Fixed syncs into Klaviyo lists.
Pricing: Free plan; paid from ~$19.99/month
8. Make
A visual canvas with branching and data transforms, usually cheaper than Zapier once a Klaviyo scenario has many steps.
What makes it different from Carly: more power, more canvas to build and debug. See Make alternatives.
Best for: Technical operators wiring Klaviyo into multi-step processes.
Pricing: Free plan; paid from ~$12/month
9. n8n
Open-source, self-hostable automation with AI nodes, for teams that want customer data on their own servers.
What makes it different from Carly: the most flexible option, and you host, build, and maintain it. See n8n alternatives.
Best for: Brands with an in-house developer.
Pricing: Free self-hosted; cloud from ~$20/month

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
