Paste one key. Eighteen flows land in your Klaviyo.
The flows themselves, not a checklist: built inside your own Klaviyo account, your logo and brand color baked in, one for every subscription moment from first subscription to win-back. Each arrives as a draft: nothing sends a word until you flip it live.
18 lifecycle events18 branded templates18 draft flows: provisioned into your account, not ours. Built by a team that spent years in the trenches with Klaviyo’s own growth, support, and data teams.
Four providers. Zero middlemen.
Klaviyo for the flows, SendGrid for direct email, Twilio for the texts, Triple Whale for the dashboard: your own accounts, your own keys, held in your own vault and never shown past their last four digits. No relay, no shared sender, no directory padding: just the stack you already pay for, wired deeper.
Events that arrive knowing everything.
A failed payment lands in Klaviyo knowing its attempt number, its recovery stage, its next retry date; a cancellation carries its reason; every event carries order value in Klaviyo’s own $value, plus a one-tap login link minted fresh for that send. Eighteen of these, streaming from the moment your key connects, and the flows you’ve already built fire on all of them.
Your segments survive the move.
Every event refreshes the profile itself: Is Subscriber, Subscription Status, Active SKUs, Subscription Value, Days Until Next Billing, Total Spent. The same product-and-value attributes you cut audiences on with Recharge, Skio, or Stay AI. Re-point your segments at the OpenSubs properties and keep mailing like nothing moved.
SKIP means skipped.
Customers text SKIP, PAUSE, RESUME, or CANCEL to your own Twilio number and the subscription actually changes: a real Shopify contract edit confirmed back in the same thread, not a “here’s your login link” dead end. CANCEL waits for a YES CANCEL before anything ends; nothing texts a customer who hasn’t opted in; STOP sticks the second it’s sent.
Every send leaves a receipt.
Everything goes out through a transactional outbox that drains every minute (retries bounded, errors preserved, each channel firing on its own so a Twilio hiccup never holds up Klaviyo), and every attempt lands on an audit row under the subscriber it touched, with delivery, opens, and clicks mirrored back when SendGrid carries the mail. New stores start quiet, toggles off and flows in draft, so the first thing your list hears is a thing you chose to say.
They count integrations. We made four count.
Your Klaviyo, eighteen events deep. Your Twilio, texting back real actions. Your SendGrid, your Triple Whale, your keys, your receipts: a stack that finally hears everything your subscriptions do.
