About this listen

In this episode, Chris Miquel sits down with LoriBeth “LB” Blair, a full-stack email solutions architect and one of the most respected deliverability experts in the industry.

LB has helped top newsletter operators, e-commerce brands, and major ESPs fix the toughest inboxing and deliverability challenges — saving clients millions in the process.

Together, we break down the real reasons your emails aren’t inboxing and what you can do today to fix them.

🔥 Topics Covered:

  • Why your content is getting filtered (and it’s not “spam words”)
  • Image compression, code bloat & secure links
  • DMARC, SPF, DKIM, and BIMI explained in plain English
  • How hackers use “list bombing” & how to protect your forms
  • Dedicated vs Shared IPs — which one’s right for you
  • When your deliverability crashes overnight (what to check first)
  • Google’s One-Click Unsubscribe enforcement
  • How LB saves brands millions on email infrastructure
  • What to audit before selling your media or newsletter business
  • Where to find LB & final thoughts

💡 Key Takeaways:

  • Bloated HTML and uncompressed images are killing your inbox placement.
  • DMARC is no longer optional. Start at p=none, collect data, then move to reject.
  • Shared IPs are fine for low senders, but serious senders need dedicated infrastructure.
  • Google now enforces one-click unsubscribes. Non-compliance = lower reputation.
  • Your deliverability = your revenue. Stop guessing, start measuring.
