I've found that email opt-ins are a powerful tool when promoting BMF.io as an affiliate. They help me capture interested leads and build a direct way to communicate. With my email list, I can send targeted offers and follow-ups. This strategy has led to higher conversions compared to random promotions. I believe consistent engagement builds trust with potential buyers. Are email opt-ins effective for promoting BMF.io as an affiliate? I'll be looking forward to your response in the comment section below.
