Yes, email listing remains important even when using push ads to promote an affiliate offer. While push ads provide instant, real-time engagement, email lists offer long-term relationship building and deeper content delivery. An email list allows marketers to follow up with potential leads who clicked on push ads but didn't convert, increasing the chance of future conversions. Emails can provide more detailed information, personalized offers, and nurturing sequences that push ads can't always accommodate. Combining both channels enhances a campaign's reach and effectiveness—push ads drive immediate action, while emails maintain engagement over time. Moreover, owning an email list gives marketers more control over their audience compared to rented ad traffic. Together, they form a powerful affiliate marketing strategy.
