Five prompts to try first

Ask in plain words. Replo answers from your own store data.

  1. “Which campaigns earned the most this month?”

    Each campaign ranked by revenue, with opens, clicks and the send date.

  2. “Compare my welcome and abandoned cart flows.”

    Revenue and click rate for each flow, email by email.

  3. “How big are my lists and segments?”

    Every list and segment with its size, biggest first.

  4. “Did email days lift Shopify sales?”

    Sales on days you sent next to days you didn't, from both apps.

  5. “Draft a Black Friday email from my best seller.”

    A draft saved in Klaviyo for you to review. Replo never sends it.

Two ways to connect Klaviyo

Klaviyo's own connector reaches Klaviyo alone. Replo joins it with your other apps and builds from the answer.

Klaviyo’s own connector

In Claude's directory
Klaviyo's listing in Claude's connector directory: “Report, strategize & create with real-time Klaviyo data”, made by Klaviyo, added January 2026
Klaviyo's own listing in Claude's directory: made by Klaviyo, sign-in required.

  1. In Claude, open Customize, then Connectors.

  2. Press Discover, search Klaviyo, then Connect to Claude.

  3. Sign in to Klaviyo and approve the access it asks for.

What it can do

  • Create campaigns and assign templates
  • Add, update and subscribe profiles

  2. Connect Klaviyo in Replo

  3. Ask in plain words

    Claude reads Klaviyo through Replo and answers, or builds the page you asked for.

    How did sales do last week?

    Replo · Shopify sales

    Larkhill made $9.8k last week, up 6% on the week before.

    A first question in Claude: a plain sentence, answered from your store.

Before you get started

  • No. Klaviyo makes its own connector in Claude's directory, which can create campaigns and update profiles. Replo reads Klaviyo with your store and ads, so one answer can tie an email to sales, and it builds the page the email links to.

  • No. Replo reads Klaviyo and can save a draft there for you to review. You send or schedule it in Klaviyo yourself, and flows stay off until you turn them on. Replo's email generator writes those drafts.

  • Yes. Replo reads your Klaviyo forms and lists, so a page it builds can carry your signup form or send new signups to the list you pick. You see the page as a draft before anything goes live.

  • Yes. Add Replo as an app in ChatGPT and the same Klaviyo connection answers there. Every prompt on this page works the same way in ChatGPT as it does in Claude.
