Native email ads typically take the form of sponsored content, product recommendations, or promotional articles embedded within newsletters or transactional emails. These ads match the style and tone of the email, enhancing user engagement without disrupting the reading experience. However, unlike web environments, email platforms limit the use of third-party scripts and dynamic ad serving, requiring marketers to use static placements or server-side personalization. Compliance with privacy regulations and email marketing standards is crucial. When executed well, native email ads can drive high engagement, build trust, and generate effective affiliate traffic directly from users' inboxes.
