Everyone picks the offer first and the format second. For VPN and utility offers, that's backwards — the format quietly caps your conversion rate before the first impression lands.

New piece breaks down where each one earns its keep:
→ Push — opted-in audiences, security angle fits the notification UI
→ Pop — volume play for trial flows, but retention offers will punish you
→ Native — narrow but real: DACH, Nordics, subscriptions

Plus a format-to-offer matrix and test budgets. Read it before your next campaign, not after.
