Newsletter sponsorship, in plain terms.
What does a newsletter ad include?
Your logo, a short blurb (about 80 words), and a CTA link, placed inside a real CTO Circle newsletter issue alongside the editorial content.
Why a 3-ad minimum?
Repetition is what drives ad CTR in newsletters — 3 placements gives you a fair read on performance. First-time sponsors can buy a single ad to test the format before committing further.
Can I see what a sponsored issue looks like?
Yes. Past sponsor placements from Inditex Tech, Astrokube, and Secfix are linked from the newsletter sponsorship section, and the full archive lives at /newsletter/history.
