POD on Etsy - Thoughts?

I am looking for practical insights and strategies regarding Proof of Delivery (POD) on Etsy. Specifically, I'm trying to understand the best practices for incorporating POD into my shipping process, especially for international orders. What are your experiences with different carriers and their POD capabilities? Are there specific services or features you rely on to ensure successful delivery confirmation and customer satisfaction, particularly in mitigating claims or disputes? Any advice on cost-effective solutions that don't significantly impact margins would be highly valuable. Curious to hear how others are navigating this.
