Postscript partner agency
SMS operator. Postscript run as part of the lifecycle program, not against it: shared cadence, shared suppression, shared identity with Klaviyo.
Postscript is the SMS platform built specifically for Shopify brands. We implement and run Postscript programs that turn opt-in lists into owned revenue: flows, Campaigns, and conversational SMS that convert without burning your list.
Postscript partner agency
Postscript is an SMS platform designed for Shopify, with deep native integration and compliance tooling for TCPA consent, A2P 10DLC registration, and CTIA/carrier filtering. Best for DTC Shopify brands where SMS is, or should be, meaningful revenue; lists above 5K aiming for 10-15% of owned revenue; teams on Klaviyo email that want a dedicated SMS platform.
What a Postscript partner agency actually does
Production-grade Postscript work, not theoretical knowledge. Each line below maps to programs we've shipped, across the platform's actual surface area, not the marketing site's.
Opt-in growth
Popups, embedded forms, two-tap opt-in, keyword campaigns, checkout collection, social-to-SMS. Sign-up tools tuned for conversion without tanking on-site engagement.
Lifecycle flows
Welcome, abandoned cart, post-purchase, win-back, and VIP triggered on Shopify events. The triggered-SMS backbone every DTC brand needs: behavioral segmentation, A/B tested.
Campaign
A planned Campaign calendar with segmented sends, send-time logic, and suppression rules against email and prior SMS. Promo cadence designed to drive revenue without driving opt-outs.
Conversational
Two-way conversational flows and keyword routing for inbound questions, product recs, and recovery. Real replies, not just blasts.
Klaviyo integration
Postscript runs SMS, Klaviyo runs email, both tied to the same Shopify catalog, segments, and predictive fields. Cross-channel suppression, shared identity, coordinated cadence.
Migrations
Attentive, Klaviyo SMS, Sendlane, SimpleTexting, Emotive, in-house. Subscriber lists migrated with consent intact, Automations rebuilt, sender identity re-registered on A2P 10DLC, zero send disruption.
Benchmark
SMS at 10-15% of owned revenue; the opt-in list growing 5-10% month over month; abandoned-cart SMS recovery above 8%; unsubscribe under 3%.

FAQ
Quick answers to what Postscript admins ask us before a kickoff. Want to dig in on something specific? Book a call and we'll walk through your account.
Can you take over our Postscript program?
Yes. And most takeovers find the same shape: half-finished Automations, a leaky opt-in funnel, A2P 10DLC registration that hasn't been audited in a year, SMS running blind to the email program next door. The first two weeks are the audit. We're in the chair by week three.
How fast does a new Automation ship?
Three to seven business days for a standard Automation: copy, design, segmentation, compliance check, QA. Multi-branch Automations coordinated with the Klaviyo email program and conversational logic typically run one to two weeks. SMS moves faster than email; the operating cadence reflects that.
Are you handling TCPA, A2P 10DLC, and carrier deliverability?
Yes. Brand and campaign registration filed on A2P 10DLC, TCPA-compliant opt-in language on every capture surface, double opt-in where the risk profile calls for it, opt-out rate and carrier filtering monitored. Compliance and carrier reputation are part of the engagement, not extra scope.
We're migrating from another SMS platform. Can you handle it?
Yes. We've moved programs off Attentive, Klaviyo SMS, Sendlane, SimpleTexting, Emotive, and in-house systems. Subscriber lists migrated with consent intact, opt-in audit trail preserved, Automations rebuilt, sender identity re-registered on A2P 10DLC, zero send disruption.
Will you write the SMS copy and build the Automations in-house?
Yes. Copy, design, segmentation, compliance, QA, conversational flows. All ours. SMS copy is craft work, not a brief you hand off; we own it end-to-end.
In their words
We had rich quiz data sitting unused. BRCG turned it into 50+ personalized flows and took email from barely contributing to 40% of our revenue.
