Why Switching ESPs Won’t Save Your Email Program with Sella Yoffe

Here’s an uncomfortable question: What if your email platform isn’t the problem… you are? 

In this episode of Email After Hours, Guy Hanson and Danielle Gallant sit down with deliverability expert Sella Yoffe to unpack one of the most misunderstood decisions in email marketing: choosing an ESP.

From misleading deliverability rankings to the myth that switching platforms will fix performance issues, this conversation challenges the way marketers evaluate ESPs altogether. Sella breaks down the reality of the shared responsibility model and where inbox placement isn’t dictated by your platform alone, but by how you use it.

The episode also dives into practical considerations like IP warm-ups, authentication protocols, and regional nuances, alongside a forward-looking discussion on how AI is reshaping the inbox.

If you’ve ever considered switching ESPs to “fix” deliverability, this episode will change your approach entirely.

What you’ll learn:

• How the shared responsibility model impacts your inbox placement
• Best practices for IP warm-up and building sender reputation
• How authentication protocols (SPF, DKIM, DMARC, BIMI) influence trust and performance
• What to consider when sending in different regions, including the Middle East
• How AI is changing email marketing workflows and inbox dynamics 

…and more!
