Summary
The consensus is that requiring an email open for resource downloads in B2B can significantly improve list quality. This practice, often referred to as 'stealth confirmed opt-in' or double opt-in, ensures email validity, increases subscriber engagement, reduces bounce rates, and enhances sender reputation, ultimately improving ROI and deliverability. Experts emphasize that it verifies active users and accurate data, reducing spam complaints and weeding out non-responsive leads. However, some sources caution that this approach might create friction, deter potential leads, and decrease overall downloads. Marketers must balance improved list quality against potential conversion losses. Clear communication, highlighting resource value, and A/B testing are recommended. A further consideration involves content format, with HTML potentially offering broader engagement than PDF, depending on the primary goal.
