There’s probably a treasure-trove of pipeline and praise getting dusty in your no-reply inbox.

In this episode of Email After Hours, Guy Hanson and Danielle Gallant sit down with Leah Miranda, Head of Demand Gen and Lifecycle Marketing at Zapier, to talk about killing one of the most destructive “best practices” in email marketing: the no-reply inbox.

For years, marketers have relied on no-reply addresses to avoid managing inbound email at scale. But as mailbox providers place greater emphasis on engagement signals and customer experience, that approach is quickly becoming outdated.

Leah explains why reply-to inboxes are no longer optional and how ignoring replies could be hurting both deliverability and customer relationships. She also walks through how she builds AI agents to create the best customer experience while keeping the human touch.

If you're still sending from a no-reply address, this episode may completely change the way you think about email.
