See how to installReview and manage Klaviyo email and SMS campaigns, newsletters, and subscriber lists. Compare results and revenue across campaigns, organize audiences into groups, and edit message content. You can also review and change flows that automatically send messages when specified conditions are met, and manage subscription status.
This skill helps people reviewing several campaigns and deciding who should receive the next message and what it should say. It also supports checking the intended audience, message body, and scheduled time before proceeding with a send.
You need the installed klaviyo CLI and a connection. Connecting requires a Klaviyo Owner, Admin, or Manager role. Changes, sends, and deletions use Hatch approval. Adding someone to a list is separate from obtaining marketing consent. Activating a flow may start sending messages, and delivered email cannot be recalled.

Use the installed klaviyo CLI. Connecting requests access to the full
supported catalog. Writes, sends, and deletions require Hatch approval.
Settings group the catalog into eight capabilities: reading, marketing
content, campaign delivery, flows, audiences and subscriptions, catalogs and
coupons, tracking and integrations, and deletion. Editing content does not
grant permission to send campaigns or delete data. Each approval still
previews the specific operation and inputs. Campaign creation and campaign/message
edits show the submitted audience, sender, subject, and message when present.
Campaign send/cancel and flow status/action approvals also show available
Klaviyo metadata; lookup failures
retain the original inputs. Audience IDs and recipient estimates are shown
when available, not inferred audience names or guaranteed delivery counts.
Run klaviyo list-tools for the compact reviewed tool catalog. These names and
their Hatch permissions are available before connection. Run klaviyo list-tools --name <tool-name> for one reviewed tool's live input schema; the
provider's output schemas are intentionally omitted to keep discovery bounded.
Do not guess tool names or argument schemas.
If klaviyo status reports auth_status: not_connected, run
klaviyo authorize-url and share only the returned connect_url. Klaviyo
requires an Owner, Admin, or Manager role. Do not construct OAuth URLs or
request tokens in chat.

The catalog covers stable remote campaign, flow, audience, subscription,
template, image, catalog, event, metric, reporting, coupon, tag, webhook, form,
review, push-token, and profile-deletion tools. Beta and local-only tools are
excluded. Klaviyo's MCP supports sending campaigns; Hatch's explicit allowlist
controls which tools can be called here. If list-tools --name reports that a
reviewed tool is unavailable, check the connection before concluding it is
unsupported. Do not invent a schema or bypass the CLI with a direct API call.
send_campaign. Sending and cancellation share a campaign-delivery
permission, separate from content editing. A successful request starts an
asynchronous job; check get_campaign_send_job and
get_campaign before reporting the outcome. cancel_campaign_send can
cancel or revert a send to draft where Klaviyo permits it; read back status.
Cancellation cannot recall delivered mail. A created draft is not sent.create_flow uses an encoded flow definition; preserve returned IDs.
update_flow changes the flow status AND all its actions. Read get_flow,
get_flow_action, and get_flow_message before and after changes. Making a
flow or action live can start delivering messages.assign_template_to_campaign_message returns a new, message-owned template
copy whose ID differs from the source. Do not retry because of that substitution;
verify with get_campaign using include=campaign-messages. Preserve returned
Klaviyo UI links when present.
