About Postscript SMS
Postscript is the leading SMS marketing platform for Shopify brands, enabling automated flows, two-way messaging, and subscriber list management. When customers reply to Postscript campaigns or text your support number, those conversations often need real answers — not just a marketing auto-reply. Connecting Postscript to Bookbag lets the AI agent handle inbound SMS conversations: answering order status questions, resolving tracking inquiries, processing return requests, and escalating to a human team member when needed — all within the SMS thread. This transforms Postscript from a one-way broadcast tool into a two-way support channel with full AI automation.
How it works together
Connect Postscript SMS and Bookbag gets the context and reach it needs to resolve more tickets automatically.
- Connect Postscript via API key and webhook configurationEnter your Postscript API key in Bookbag and configure Postscript to forward inbound SMS messages to Bookbag's webhook endpoint. Outbound replies flow back through Postscript's sending infrastructure.
- AI handles inbound SMS replies automaticallyWhen a subscriber replies to a Postscript campaign or sends an inbound message, Bookbag receives it via webhook, identifies the customer using their phone number, and generates a reply using live Shopify order data.
- Resolve order and support questions within the text threadBookbag answers order-status, tracking, and return questions entirely within the SMS conversation — keeping the customer in the same channel they initiated contact from without redirecting them elsewhere.
- Escalate to Postscript human agents when neededWhen a conversation requires a human agent, Bookbag flags it in Postscript's inbox with a conversation summary so your team can take over without the customer having to repeat themselves.
Benefits
Convert two-way SMS into a full support channel
Most brands ignore or use basic auto-replies for inbound SMS. Bookbag makes every inbound reply a handled support interaction — resolving issues instantly without the customer needing to switch to email or chat.

Customers who have unresolved support issues are more likely to opt out of SMS marketing. Bookbag resolves those issues in the text thread — reducing opt-outs driven by frustration.

SMS customers expect fast replies. Bookbag ensures every inbound SMS message gets an immediate response at any time of day — matching the channel's expectation of near-instant engagement.
