If you’re building an email list, you’ve probably seen the terms single opt-in and double opt-in — but which one should you choose, and why does it even matter?

In this episode, Charly breaks down the key differences between single and double opt-in, and how each impacts your compliance, deliverability, and lead quality.

✅ You’ll learn:

- The legal implications under spam legislation like the Spam Act

- Why double opt-in helps you maintain a cleaner, more engaged list

- How single opt-in can increase list size — but at what cost?

- How to choose based on the “heat” of your leads and your marketing goals

- Tips for reducing friction in the signup process while staying compliant

Don’t just guess. Understanding opt-in methods can protect your reputation and improve your email results.
