Should I collect phone numbers or just emails?

As an e-commerce business owner, I'm trying to optimize my customer data collection strategy. I want to improve my marketing reach and customer communication, but I'm uncertain whether collecting phone numbers provides significant advantages over email collection. What are the pros and cons of collecting phone numbers versus email addresses? Are there specific scenarios where phone numbers become more valuable, or should I stick to email communication?
