SMS Sales, Responses

Postscript

Summary
As part of a greenfield initiative at Postscript, I helped design a conversational sales workspace that enabled human sales associates to engage subscribers via SMS. This work focused on scaling responses, improving context, and routing conversations, resulting in a full redesign of the Responses inbox.

Background & Objectives


Postscript made a strategic bet on conversational selling: using human sales associates to engage subscribers over SMS and drive revenue. This initiative, later called SMS Sales, had the potential to become a major pillar of the business.

I joined as the sole designer to help define what this product could be, starting from an experience that wasn’t built for this use case at all.

Challenge


The existing messaging experience (“Responses”) was designed for lightweight, reactive conversations—not for:

  • High-volume outbound messaging

  • Sales-driven workflows

  • Context-rich interactions

Sales associates needed to move quickly, personalize outreach, and manage multiple conversations at once, but the product lacked the structure and context to support this.

The core question became:
What does a workspace for conversational selling actually look like?

Role

I was the sole designer across discovery and definition, and partnered with Product, Engineering, and Sales leadership to further define the problem space and validate design direction. I also led research with internal sales associates and managers and translated sales workflows into product direction.

Context is key

I spent time with in-house sales associates to understand how they were working in practice. My goal was to find out:

  • What slowed them down

  • How they managed conversations

  • What information they needed to sell effectively

A consistent theme emerged:
Context was the difference between a generic message and a successful sale.

At the same time, I drew on my experience in shared inbox systems (Help Scout) and explored adjacent tools like CRMs to understand how other products handled high-volume communication, routing and ownership, and contextual data.

Design Direction: Context-Driven Selling

As I began to put pen to paper, I focused on a core idea to guide my direction:
Give sales associates the context they need, where and when they need it.

This meant rethinking the inbox as more than a message thread, and instead as a workspace for decision-making.

Key directions included:

  • Surfacing relevant subscriber data directly in the conversation

  • Supporting faster replies through saved responses and macros

  • Exploring routing and ownership models for scaling conversations across a sales team

  • Designing for both speed (high volume) and personalization

Exploration & Prototyping

Because the product was still being defined, much of my work focused on making ideas tangible quickly to get feedback and drive the conversation forward. Some motions that helped with this phase:

  • Creating visual wireframes to communicate direction across teams

  • Building prototypes to explore different interaction patterns

  • Using these artifacts to align stakeholders and drive product decisions

For example, I explored a mobile-first version of the sales inbox, testing patterns for:

  • Saved replies and macros

  • Conversation routing

  • Managing conversations on the go

These prototypes helped clarify tradeoffs and shape the direction of the product.

Outcome & Reflection

This work helped define the foundation for what became SMS Sales and influenced how Postscript approached conversational selling as a product space.

While SMS Sales as a product is being sunset, the project remains a strong example of:

  • Designing in ambiguous, 0→1 spaces

  • Translating real-world workflows into product systems

  • Introducing structure and context into underpowered tools

  • Using design artifacts to align teams and shape strategy

The project also helped inform Postscript’s AI selling solution, Shopper, which employs some of the same strategies that were successful in SMS Sales.
