One Klaviyo connection, and what each tool needs from it
Most of the work only reads your account. The two actions that write to Klaviyo say so up front, and they only need the permissions listed here.
| Tool or action | What it needs |
|---|---|
| Email Checker, Signal, Share Links, Revenue Diagnosis, Customer Journey | Read access to the Klaviyo account |
| Slicer: publish a template into Klaviyo | templates:write and images:write |
| Email Checker: set a campaign back to draft | campaigns:write |
| Signal: verify discount codes | A Shopify connection with read access to discounts |
Frequently asked questions
What Klaviyo tools does Retentive include?
Six: the Klaviyo Email Slicer, Email Share Links, the Klaviyo Email Checker, the link and discount code checker (Signal), Revenue Diagnosis and the Customer Journey audit. They run on one Klaviyo connection, next to Retentive's campaign and flow analytics.
Do the tools work with Klaviyo flows as well as campaigns?
Yes. The Email Checker checks flow emails, Signal scans every live flow, the share links work on flow emails, Revenue Diagnosis splits flow revenue from campaign revenue, and the journey audit shows how flows overlap for real subscribers.
Which Klaviyo permissions do the tools need?
Reading the account covers the checks and the analysis. Two actions write to Klaviyo and need a key that allows it: publishing a template from the Slicer (templates:write and images:write) and setting a campaign back to draft from an Email Checker report (campaigns:write). A Full Access key covers both.
Do I need Shopify?
Only to verify discount codes. Signal looks codes up in Shopify; without that connection it still checks every link and marks codes as unverified instead of guessing.
Is each tool a separate subscription?
No. Every tool ships inside Retentive and runs on the same Klaviyo connection. AI-powered steps, such as a proofreading check, use AI credits from the account's monthly allowance.

About Retentive's Klaviyo tools
Retentive is a Klaviyo intelligence platform for email, retention and lifecycle marketers, and it ships six production tools that run on the same Klaviyo connection as its analytics.
Two of them are QA tools. The Klaviyo Email Checker proofreads emails before they send, including the text inside images, and with auto-check turned on it proofreads every scheduled campaign and emails an alert that quotes the problem. The link and discount code checker scans live flows and scheduled campaigns for broken links and for discount codes that are missing, expired, or set to expire before the send, verified against Shopify.
Two are production tools. The Klaviyo Email Slicer turns a flat design image into a native drag-and-drop template with a link and alt text on every slice, and Email Share Links turn any campaign, template or flow email, drafts included, into a link a client can open without a Klaviyo login.
Two are analysis tools. Revenue Diagnosis explains why revenue moved by splitting the change into campaign, flow and non-email revenue against the previous period and last year, and the Customer Journey audit rebuilds real subscribers' email timelines to find same-day pileups, overlapping flows and sends after an unsubscribe.
