What makes Dupple different

Five things we can show, not just claim.

01

Three sponsors per issue, at most

Each newsletter carries no more than three sponsors, so an ad is one of three messages, not one of hundreds. LinkedIn Ads and Meta Ads run open auctions where any number of advertisers bid on the same feed.

02

Fixed prices, no auction

Advertisers pay a fixed price per placement that they know before booking. On auction platforms such as LinkedIn Ads, the price moves with competing bids.

03

Reports name the companies that clicked

Every campaign report lists opens, clicks, CTR and the corporate email domains that engaged. Ad platforms report their own metrics only, so sales teams get no account list to follow up.

04

Audiences measured weekly

Subscriber counts and open rates on this page are pulled from our email platforms every week and rounded, not typed into a media kit once a year. Techpresso averages a 37% open rate.

05

Paid placements are disclosed

Sponsors buy labelled slots in the newsletters. On dupple.com a vendor can also pay to be listed in a guide or to sponsor an article, and that page says so under its title. Our affiliate disclosure explains how we make money.

The team behind Dupple

Dupple started as one newsletter in 2023. The news was everywhere and the signal was nowhere, so Techpresso became a daily briefing you could finish with your coffee. Readers forwarded it to their teams, and one newsletter became six.

Dupple is still a small, founder-led team. Each newsletter has its own editor and its own sources, and no content farm sits in the middle.
