Editing Double opt in vs. single opt in (section)

=== Best practices and tips ===
- **Assess your audience**: If your business relies heavily on engagement and deliverability, consider using '''double opt-in''' to maintain a high-quality contact list.
- **Monitor engagement**: For businesses that prioritize quick list growth, '''single opt-in''' may be more effective, but keep an eye on engagement metrics and spam complaints.
- **Stay compliant**: Depending on your country or region’s emailing regulations, using the '''double opt-in''' method may help you comply with legal requirements that protect consumer consent.
- **Communicate clearly**: Let your contacts know what to expect after they submit their information, regardless of which opt-in method you choose.
