The Validity Electronic mail Deliverability Benchmark Report measures one thing completely different: advertising and marketing e mail inbox placement for senders utilizing established platforms.

AI is reshaping how e mail campaigns are constructed and measured

AI adoption in e mail advertising and marketing is exhibiting up in manufacturing timelines and ROI gaps greater than in adoption charges alone. Litmus surveyed 502 entrepreneurs throughout the US, UK, Australia, and New Zealand in late 2025, and located the next:

• Generative AI is probably the most impactful AI use in e mail advertising and marketing, cited by 22% of entrepreneurs, forward of personalizing content material (15%), marketing campaign evaluation (15%), and bettering deliverability (12%).

That’s the reason the hole widens on the high of the distribution.

Personalization in e mail is not a marketing campaign enhancement. The shift towards e mail record segmentation as an always-on apply is taking part in out most clearly in e mail, the place focusing on instantly determines whether or not messages are delivered, opened, and transformed. 

The information reveals a widening divide between packages utilizing real-time behavioral triggers and people counting on demographic segmentation alone:
