SMS Drip Campaigns for Customer Onboarding and Retention

Introduction

As a Marketing leader in the SaaS industry in Singapore, you're likely no stranger to the challenges of customer onboarding and retention. One of the most effective ways to tackle these challenges is through SMS drip campaigns. However, with the ever-evolving regulatory landscape and the need for higher delivery rates, it's essential to have a well-planned strategy in place. In this playbook, we'll explore how to create effective SMS drip campaigns for customer onboarding and retention in Singapore, while ensuring compliance with the Personal Data Protection Act (PDPA) and maximizing return on investment (ROI).

Why SMS fits promotional Drip Campaigns

SMS remains a highly effective channel for promotional drip campaigns in Singapore due to its ability to reach customers instantly and its suitability for time-sensitive communications. With the rise of mobile-first strategies, SMS is well-suited for reaching customers on-the-go. Compared to other channels, SMS offers a more straightforward and widely supported solution, making it an excellent choice for promotional traffic.

How the program works end-to-end

To create an effective SMS drip campaign, you'll need to set up a workflow that integrates with your HubSpot CRM and CRM Messaging. Here's an overview of how the program works:

  • Contact fields: Store customer data, including phone numbers and consent status, in your HubSpot CRM.
  • Triggers: Set up triggers in HubSpot to initiate the SMS drip campaign, such as when a customer signs up for a free trial or makes a purchase.
  • Owner handoffs: Assign owners to each stage of the campaign, ensuring that the right person is notified and takes action at the right time.
  • CRM Messaging: Use CRM Messaging to send personalized SMS messages to customers, based on their interactions and preferences.

Compliance notes for Singapore

When it comes to promotional SMS traffic in Singapore, compliance with the PDPA is crucial. Here are some key considerations:

  • PDPA compliance: Ensure that you have obtained explicit consent from customers before sending them promotional SMS messages.
  • DNC registry: Register with the DNC registry to ensure that you're not sending messages to customers who have opted out.
  • SMS sender ID: Use a registered SMS sender ID to identify your messages and comply with regulations.
