Email marketing has survived multiple attempts by the tech media to declare it officially dead. The latest declaration of its demise suggests that AI-driven search and automated content will make email obsolete. Reality says otherwise. Email marketing is alive and well. And it is better than ever, thanks to the intelligent inbox.

One thing that has changed in recent years is the marketer’s approach to email. The days of ‘spray and pray’ are over. Sending out massive amounts of emails to every inbox willing to accept them is no longer a reasonable strategy. Email marketing success now requires understanding how Google and Apple – the two most dominant email providers in the world – act as gatekeepers.

The Intelligent Inbox Is AI Driven

Email marketing remains profitable. According to data from late 2025, 30% of all digital marketers report that their email marketing efforts returned $10-$36 for every dollar spent. An additional 35% report that their efforts are paying off at a rate of $36-$50 per $1 of spend.

That is good news. But to keep it coming, digital marketers need to understand the intelligent inbox. Google and Apple’s respective AI tools – Gemini and Apple Mail AI – give users the ability to generate email summaries. A user can understand the point and context of a given email without ever opening it.

This is a problem because AI summaries can both inflate perceived open rates and limit genuine click-throughs. Neither scenario is good for email marketers. That means the new goal is to provide unique information that will both appear in an intelligent inbox summary and encourage the recipient to open and read.

3 Core Parameters

Modern email services give users an opportunity to prioritize their emails according to importance. To maintain a high priority status for marketing emails, an organization’s email strategy must align with three core parameters:

• Authentication – SPF, DKIM, and DMARCA are no longer optional. They are both mandatory and the bare minimum. Without proper authentication, AI mail services will flag a sender’s domain as a security risk.

• Micro-Behavioral Triggers – Information gained for email marketing purposes is rooted in observing micro-behaviors. For example, an abandoned cart would trigger an automatic email based on old standards. The new standard is to look for more detailed behavior, like hovering over a product image for a few seconds.

• Hyper-Personalization – Modern email marketing must make use of AI technologies to hyper-personalize messages. AI tools can take a generic message and dynamically adjust its tone, imagery, etc. based on recipients.

Each of these three parameters not only satisfies AI gatekeepers, but they also increase deliverability and encourage user engagement. And according to San Diego-based Pixsan, engagement is the entire purpose of email marketing.

Email Marketing Best Practices

Pixsan Solutions suggests that adhering to best practices helps email marketers make the most of the modern intelligent inbox. Here is what they recommend:

• Front-loading value by placing the most critical information in the first sentence or two.
• Prioritizing zero-party data to improve email targeting.
• Optimizing email messages via information gain (the process of including unique information)
• Tracking where emails end up in the intelligent inbox (the ‘priority’ tab is the goal)

The intelligent inbox is helping consumers be more task-oriented with their emails. Low-priority messages are either being ignored or simply deleted. High-priority messages are summarized by AI, at a minimum. For the email marketer, the challenge is getting recipients to open and read those messages.

Email marketing is by no means dead. It is changing thanks to AI and the intelligent inbox. It is up to marketers to adapt accordingly.
