SMS marketing is a powerful tool for customer engagement, with high open rates and click-through rates. However, securing internal stakeholder support can be challenging. To overcome this, it's essential to prepare a solid pitch that highlights the benefits of SMS marketing, including measurable ROI, increased loyalty, and growth. Marketers should start by assessing their current SMS strategy and gathering information on existing providers, pricing models, and technical requirements. They should also develop a mini business case using tools like Twilio's texting for marketing ROI calculator to demonstrate potential ROI. The pitch should include key criteria for success, such as tech stack integration, viewability, trackability, deliverability, scalability, trust & compliance, timeline, implementation resources, and financial summary. By following these steps, marketers can secure approval, budget, and support from internal stakeholders and start building a successful SMS marketing program.
