Email deliverability in 2026 and beyond: what changed, what broke, and how to prepare for 2027.

Google finished sunsetting Postmaster Tools v1, sender enforcement tightened, and a new set of standards started landing. If your team still reads historical reputation scores and runs the authentication setup it stood up years ago, your mail is the mail that quietly stops arriving.

Presented by Matthew Vernhout of Email Industries.

What we cover.

Six changes from this year, each one with what it does to your sending and what it asks of you before 2027.

  1. The Google Postmaster Tools shift

    What the complete sunset of v1 means for the data you used to plan against, and how to work in the compliance-first era of Postmaster Tools v2.

  2. New filtering and blocklists

    The impact of Validity’s new Heatwave blocklist on inbox placement worldwide.

  3. Authentication upgrades: DMARCbis and DKIM2

    The changes the published DMARCbis spec requires, including the np= and t= tags, and where the DKIM2 rollout actually stands.

  4. Google’s rules for political senders

    How Google’s certified sender program works for political and advocacy mail, and what it signals for commercial senders next.

  5. Gmail’s AI inbox and sender enforcement

    How Gmail’s AI-driven inbox decides what to put in front of a reader, and how stricter enforcement treats a sender who is out of compliance.

  6. The Yahoo and Comcast ecosystem shift

    What the Yahoo and Comcast migration changes about consumer inbox delivery, and what it means for the way you manage a list.
