It is booked through the platform's self-serve ad tool, such as Google Ads or Meta Ads, or with a publisher like GMX through its sales team. Four publishers list it today.

What you supply
A subject line, a short preview text, an image and a landing page link.
Best for
Reaching people while they check email and driving clicks to an offer.
Before you buy
Inbox placements often have strict rules, so check how the ad is labelled and which audiences can be targeted.
