Myth: Privacy and consent rules killed data-driven marketing

Myth: Privacy and consent rules killed data-driven marketing

The doom take: GDPR/ATT/cookie death means you're flying blind now. The correction: first-party, consented data plus server-side collection is more durable than the third-party signal you lost — the teams who rebuilt early are ahead.

— A thread on server-side tagging as the post-cookie collection layer.
— Simo Ahava's server-side GTM material — the reference everyone borrows from.
— A piece on consent-mode modeling and what you can still measure.
— A checklist for a first-party data foundation that survives the next deprecation.

Skip if you migrated server-side already. Essential if your tracking still leans on third-party cookies.

That's the stack for this week. Forward to a teammate.
