Top-of-issue placement above the main content. Roughly 75–100 words plus a logo or image and a link. One primary sponsor per issue — you’re not competing with three other brands for the same eyeballs.
Four-issue package: $1,200 (save $200)
Dedicated post — $1,000
A standalone email to the full list, plus a permanent post in the archive. Written by you, or drafted by us to fit the newsletter’s voice — your call. Limited to four per year, so these book out well in advance.
