Outgrew Klaviyo at $5M.
Run promo, transactional & RCS on one stack.
DTC brands moving their SMS program to Pinnacle ship richer messages, run order updates and marketing on one API, and turn on RCS without a second vendor. The lift shows up in the next campaign report.
Forrester TEI commissioned by Google, Feb 2026 · figures reflect best reported lift versus SMS.
What it actually looks like
Branded sender, product cards, checkout buttons — natively, on the customer's default messaging app.
Your SMS platform was built for $1M brands.
At 100k+ messages/month, the marketing-only stack starts costing you growth. Three places it shows up first.
SMS is locked into flows
Send-on-event triggers live inside a flow builder you can't reach from your own backend. Engineering wants to send order confirmations and the marketing tool says no. So you end up with two SMS providers — and two sender numbers your customers don't recognize.
Credits expire monthly
You're paying for messages you haven't sent yet, and you forfeit them every 30 days. Worse, list-size tiers punish you for collecting opt-ins. The unit economics get worse as your list grows — exactly when they should get better.
RCS is bolted on (or missing)
When the marketing platforms eventually ship RCS, it's a thin wrapper over their existing SMS pipes. No native RCS analytics, no clean way to A/B SMS vs RCS revenue, no rich cards in your transactional flows. You can't justify the channel switch with the data you have.
Marketing-only platforms vs. Pinnacle
What changes when promo, transactional, and RCS run on the same stack.
| Capability | Klaviyo · Attentive · Postscript | Pinnacle |
|---|---|---|
| Promo blasts | Yes — that's their core | Yes |
| Transactional (orders, shipping, fraud) | Bolt-on or second vendor | First-class, same API |
| Native RCS (rich cards, carousels, branded sender) | Limited or roadmap | Day-one, with native fallback |
| Direct API for engineering | Marketing-flow oriented | Full REST API + webhooks |
| Two-way conversations | Limited / extra cost | Built-in, agent-routable |
| Pricing model | Credits, list-size tiers, monthly expirations | Pay-per-message, no expirations |
| RCS-vs-SMS revenue analytics | — | Side-by-side by segment |
Don't pay thousands just to try RCS.
Klaviyo, Attentive, and Postscript gate RCS behind enterprise tiers, annual contracts, and platform fees in the thousands per month — before your first rich message goes out. Pinnacle is pay-per-message, no minimums, no contracts. You can spin up real RCS sends for the cost of a dinner.
$0 platform fee
No seat fees, no setup fees, no "RCS tier" upgrade. The marketing platforms charge thousands per month for the privilege of having RCS in their roadmap. We charge for messages — that's it.
No minimums or contracts
Send 100 messages or 10 million. No annual commitment, no quarterly minimum, no penalty for a slow month. Spin up, spin down, walk away — without a procurement cycle.
Cheapest per-RCS rate
RCS Basic costs less than the SMS you're sending today. RCS rich (cards, carousels, branded sender) costs less than the platform tax other vendors layer on. Apples-to-apples, we're the lowest entry price on the market.

- • Flow-by-flow migration from Klaviyo / Attentive / Postscript
- • 10DLC, toll-free, and RCS sender registration handled
- • Side-by-side analytics: SMS vs RCS revenue, by segment
- • No setup fee, no SOW, no professional-services line
We were paying Klaviyo for SMS credits we kept losing every month and Twilio for order confirmations on a number our customers didn't recognize. Pinnacle replaced both with one stack — and our post-purchase RCS flow alone paid for the migration in the first week.
One stack, every message your store sends
From the welcome series to the shipping update — same API, same sender, same opt-in pool.
Promo + transactional, one API
Welcome flows, abandoned cart, post-purchase, order confirmations, shipping updates, fraud alerts — all sent from one branded RCS sender.
Native SMS / MMS fallback
Devices without RCS get the same campaign as SMS or MMS automatically. No double-sending, no extra setup, no lost reach.
Side-by-side revenue analytics
Per-segment, per-flow CTR / conversion / AOV / revenue per recipient. The dashboard your CFO wants when you ask to scale RCS spend.
Shopify-native flows
Abandoned cart, browse abandonment, back-in-stock, post-purchase, and review request flows wired up to Shopify out of the box.
Two-way conversations
Customers reply to your campaigns. Replies route to your support agent or LLM, with full thread history per recipient.
Pay-per-message pricing
No credits. No expirations. No list-size tiers. RCS priced as its own line so you can model lift without arguing with a sales rep.
