1. Hyper-Personalization Is the New Standard
One of the top email marketing trends in 2025 is hyper-personalization. Gone are the days of generic broadcasts. Subscribers now expect emails tailored to their needs, behavior, and preferences.
For your solo ads business, this means:

AI gives you more clicks per campaign, meaning happier buyers and higher conversions.
3. Mobile-First Emails = More Clicks
