Abstract
This study investigated the impact of AI-generated email content on email marketing deliverability, specifically its placement in spam folders. A controlled experiment was conducted with 450 participants who received AI-generated emails sent from different domains using plain text content and clear subject lines. The emails were analyzed for placement in inboxes or spam folders based on participant responses. The results revealed no significant impact of AI-generated content on email deliverability, regardless of the sender's domain or the recipient's email provider. All emails consistently reached primary inboxes, suggesting that the applied precautions (plain text, clear subject lines, and avoidance of suspicious elements) mitigated any potential spam triggers. This study shows AI-generated email content can be deliverable and personalized, challenging concerns about spam placement. Marketers can use AI to craft engaging emails that land in inboxes, not spam folders. This finding also aligns with SEO trends, where AI content isn't automatically penalized.
