FAQ
Questions we hear.
Is BRCG a certified Postscript partner?
Yes. BRCG is a certified Postscript partner agency. We ship SMS programs on Postscript for Shopify DTC brands and pair Postscript with Klaviyo for the most common cross-channel stack.
How does Postscript compare to Attentive?
Postscript is Shopify-native and best for DTC brands where SMS pairs with email (typically Klaviyo) and revenue per recipient matters. Attentive is multichannel and standalone-strong — better for brands running SMS as a primary channel at scale. Both are certified BRCG partners — we'll tell you honestly which fits.
Does BRCG implement Shopper conversational AI?
Yes. BRCG implements Shopper (Fall 2025) with brand-voice guardrails configured in Brand Center. We roll it out gradually with quality monitoring and conversation review before opening it to full traffic.
Can BRCG migrate us from another SMS provider to Postscript?
Yes. Migrations from Attentive, SimpleTexting, or in-Klaviyo SMS to Postscript typically take 3–4 weeks: list import, opt-in re-confirmation, 10DLC registration, Automation rebuild, parallel-run validation.
What's required for 10DLC compliance on Postscript?
10DLC requires brand registration with The Campaign Registry, campaign type registration, and TCPA-compliant opt-in language across all capture surfaces. BRCG handles the pre-flight as part of every Postscript engagement.
In their words
What the teams say.
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.
