Reach people who use AI at work
Kortex Daily is a five-minute email and a site for researchers, teachers, marketers and builders who use AI tools every week. A sponsor card sits inside the issue, labeled Sponsored, next to stories about the tools your buyers already use.
We have not published reader numbers yet. When we have measured them, they go here, and nowhere else.
What a sponsor card looks like
These samples use placeholder text. Each one is drawn the way it appears in the issue, in the order a reader meets them.
Logo, image, headline, body and one button. The only paid block above the first story.
Headline, body and one button. An image is optional.
Sits above the tools we picked, marked Sponsored, and gets its own page in the Directory.
A single text line. No image.

Rules we keep
- An ad never changes a story. Sponsors cannot ask us to cover, rewrite, hold or rank anything. A story runs the same with or without an ad near it.
- Plain labels. Paid blocks say "Sponsored". Our own promotions say "From Kortex" and only fill slots nobody bought.
- Lead time. Book at least 3 days before the issue date and no more than 60 days ahead.
- Fit. We decline ads that mislead, are unsafe, or have nothing to do with AI at work.
- Payment. We reply by email with a payment link and the creative checklist. Nothing is charged before that.
