An engine,
not an inbox monkey.
Cadence is the operator portal we use to run every client's Klaviyo. It's software — not a Notion doc, not a project tracker. We push templates, segments, and campaigns into your account via the Klaviyo API. You preview everything. You hit confirm. Nothing ships without you.

Capabilities
What the platform actually does.
Every action below is a real Klaviyo API call — not a manual checklist we run in the Klaviyo UI for you.
Push email templates
Magazine-grade HTML pushed straight into the client's template library. Inline CSS, brand-kit injected. CODE editor type, not drag-and-drop.
Upload + host imagery
Drop a PNG/JPG/GIF. We upload to the client's Klaviyo asset library, then wrap it in an editorial template ready to send.
Schedule campaigns
Pick a list, pick a template, set the schedule (or use Smart Send Time). Campaign lands in Drafts. Operator commits manually.
Create lists + read segments
Build segments with conditional logic via the API. Pull existing segments to pick audiences for campaigns.
Deploy full flows
Author once in our master account, clone the definition into each client account with brand-kit substitutions. Author-once-clone-many is the only sane API pattern.
Compliance review pipeline
Every supplement send auto-checked against FDA structure/function disclaimer rules + restricted-claim language before staging.
Bulk profile import
Up to 1,000 profiles per request. Subscribed historical lists onboarded in minutes.
Webhook event ingest
Subscribe to email/sent, opened, clicked, bounced, unsubscribed. Real-time campaign performance streamed into the portal.
The runtime
How a flow actually ships.
Pick
Operator picks a flow template from the master library — welcome, abandoned cart, replenishment, etc.
Inject
Brand kit (palette, type, voice, hero photography) is injected into every email in the flow.
Preview
Operator reviews the rendered HTML for each email side-by-side with the brand kit.
Push
Confirm. CODE templates are written into the client's Klaviyo via API. Idempotent.
Wire
Templates are linked into the flow shell. Operator flips the flow live in Klaviyo when ready.
No drag-and-drop nonsense. CODE templates only — magazine-grade HTML, inlined CSS, brand-kit injected. Klaviyo's drag-and-drop editor is capped at 2 templates per partner across all installs; we built around it from day one.
Orchestration
Every flow,
in one orbit.
Welcome, cart, browse, post-purchase, replenishment, win-back, VIP, drop hype — every flow Cadence ships shows up in your Klaviyo as a real automation, observable from a single dashboard.

Security
Your account,
your control.
Per-client OAuth (or scoped private keys), encrypted at rest with AES-256-GCM via KMS. Audit log on every write. Least-privilege scopes. Revoke any time from Klaviyo's API Keys settings — we lose access in the same second.
Encrypted at rest
AES-256-GCM per-client data keys, KMS-wrapped envelope encryption.
Audit log on every write
Operator, client, endpoint, payload hash, response code — all retained for 12 months.
Least-privilege scopes
OAuth installs request only the scopes needed for the agreed-on workflow.
Manual confirm on writes
Every API write the portal makes against your account is gated by an explicit operator confirmation.
Revocable any time
Revoke the key in Klaviyo's Settings → API Keys. We lose access on the next request.
Want a live demo of the portal?
30-min call. We'll connect a sandbox Klaviyo, push a flow live, and walk you through the operator side end-to-end.
