To keep everyone aligned and move from “one-off experiments” to a shared plan, use these prompts with your team.

Team Conversation Starters

Use these conversation starters to help your team align on priorities, review performance, and identify the most impactful next steps with SMS.

• Are our SMS sends aligned with high-intent moments?

• Which segments convert best through SMS?

• Are we balancing frequency to avoid audience fatigue?

• Which templates need testing or refinement?

• Are we using SMS where it drives the most ROI (e.g., reminders, alerts)?

• What is our #1 business goal for SMS this quarter: engagement, reactivation, or conversions?

• Where do we see the biggest drop-off in your SMS funnel, delivery, clicks, or conversions?

• How are we currently segmenting your users? Should we explore predictive or RFM segmentation together?

• Would we like to test a triggered SMS journey next, maybe tied to a cart or browse event?

These discussions will surface where you are today and what your team expects from SMS in the next 1–3 quarters.

Next, let’s connect SMS to the bigger picture: how it supports your growth, retention, and Ever Success goals.

Strategic Guidance: Connect SMS to your goals

Strategically, SMS works best when it supports a clear set of business outcomes rather than running as a standalone channel.

1. Set up for Success:    

   • Validate integration, enable Two-Step Method, register Sender ID, set up VCC, and ensure opt-in/unsubscribe compliance.

   • Set Silent Hours to prevent delivery during restricted times.

2. Execute with Precision:    

   • Launch Quick Response Templates for instant messaging.

   • Use triggered SMS for real-time journeys (cart, order, renewals).

   • Personalize content and optimize timing.

3. Optimize for Impact:    

   • Monitor SMS Analytics and Subscriber Analytics (Audience Growth & Health).

   • Cross-check transactional events in UCD.

   • Refine segmentation and iterate on content.

4. Scale & Sustain:    

   • Analyze results and tie SMS metrics to business outcomes.

   • Share insights and expand best practices to new segments or regions.

Once you’re clear on the role of SMS in your overall strategy, it’s time to tailor your approach to your current maturity level.

The playbook below helps you focus on the right actions based on where you are today, from early activation to advanced optimization.

Strategic Playbook by Stage
