The choice between single and double opt-in depends on your specific needs and goals:
Single Opt-In: This method simplifies the subscription process, potentially increasing your list growth rate. However, it may result in a higher percentage of invalid email addresses and spam complaints. Double Opt-In: Although this method involves an extra step, it helps ensure the quality of your email list. Subscribers are more likely to be genuinely interested in your content, leading to higher engagement rates and fewer spam reports.
