AI in the inbox is exciting. It is also imperfect.

In the latest episode of Email’s Not Dead, our guest Al Iverson talks about an early AI inbox example where a phishing email was labeled as “important.” It shows that AI is still learning, and not every user will rely on it to organize their inbox.

The takeaway for senders? Focus on creating valuable emails and following deliverability best practices.

Think email bounces are simple?

4xx = retry.
5xx = delete.

That’s the rule most people learn. But in reality, bounce codes are more like signals than laws.

Some “temporary” failures will never resolve. Some “permanent” ones can recover later. And mailbox providers don’t always use the same logic.

In this month's Bounce House, we break down:
- Why bounce codes are often misleading
- The difference between retrying a message and trusting an address
- How to spot patterns that actually matter

Stop reacting to the number and start understanding the message.

This week the Bounce House goes meta and talks about bounces. Not the fun kind. The kind that shrinks your list while you follow the 'rules'.

Imagine spending weeks building a campaign, and AI decides it’s not worth showing.

That’s the reality inside inboxes powered by tools in Gmail, Microsoft Outlook, Yahoo Mail, and Apple Mail.

We’re talking about how to work within those systems – not against them – in our next Deliverability Academy webinar.

AI inboxes are changing how people read email.

In the Season 7 premiere of Email’s Not Dead, deliverability expert Al Iverson shares a simple idea that could make a big difference for email marketers: learn from newsletters.

Why? Because people actually sign up for newsletters to read them. They expect value, and they engage with the content.

If your emails are easy for AI to summarize into a single sentence, it might be time to rethink your strategy.

Quick question:

If AI is reading and summarizing your emails before your subscribers do… are you optimizing for that?

Authentication still matters.

Reputation still matters.

But in the AI inbox era, engagement signals matter most.

In the next Deliverability Academy session, we’re breaking down what that actually means, without the fluff.
