About this episode
Hitting the inbox is harder than ever. In this episode of the Audience Bridge Podcast, I sit down with Kyle Renfrow, CEO & CTO of ESP OptiPub, to talk about what really moves the needle for email deliverability in 2025.
We cover:
✅ How Yahoo & Gmail’s latest changes are impacting inbox placement
✅ Dedicated vs Shared IPs – and the hybrid model most marketers overlook
✅ The deliverability data your ESP isn’t showing you (and why it matters)
✅ Scaling to high volumes without destroying your sender reputation
✅ Actionable steps to protect and improve your domain reputation
If you’re sending newsletters, campaigns, or high-volume email, this conversation is packed with strategies you can implement immediately.
