The Rise of AI in Email Marketing: Apple Intelligence and AI-Generated Summaries

Email marketing is evolving faster than ever, and artificial intelligence (AI) is at the heart of this transformation. Apple stepped into the spotlight with the introduction of Apple Intelligence in iOS 18.1, which brings AI-powered features to the native Mail app. 

For small businesses, this shift represents both opportunities and challenges for how you connect with your audience. At Good Call Marketing Agency, we help small businesses navigate these changes to stay ahead in their marketing strategies.

Apple Intelligence and AI-generated email summaries:

Apple Intelligence introduces AI-generated email summaries, designed to make inboxes easier to manage. These summaries appear in two key ways:

1. Inbox View:
   • AI analyses incoming emails and generates a summary below the subject line, replacing the traditional preview text.
   • For marketers, this is a significant shift—preview text has traditionally been “prime real estate” to engage recipients. With AI summarising emails automatically, subject lines and email content need to work even harder to capture attention.
     
     
2. Email Message View:
   • After opening an email, users can tap a “Summarise” button to generate a concise summary of the email’s content.
   • While helpful for long email threads, this feature is optional and may be used less frequently than the inbox summaries.

What this means for marketers:

The introduction of AI-generated summaries is a wake-up call for email marketers:

• Subject lines are more important than ever:
  With the preview text potentially replaced, the subject line becomes the main driver of opens. Make sure it clearly conveys urgency, relevance, or value.
  
  
• Maintain engaging email content:
  Even if AI summarises emails, the actual email content still matters. Focus on concise, scannable content that delivers value immediately.
  
  
• Monitor and adapt:
  Apple Intelligence is new, and not all users will see these summaries immediately. Start tracking performance on Apple Mail devices and adapt your strategy as more users adopt the update.

Apple Mail Usage Statistics

Understanding how users access their emails is key to preparing for the impact of Apple Intelligence. According to data from StoneShot (2025):

• Mobile email activity accounts for around 25% of all email opens.
• Of that mobile activity, iPhones make up approximately 60–70%, highlighting the dominance of Apple devices on mobile.

On desktop, Safari on Mac represents only about 5% of email opens, while Outlook accounts for 60–70% of desktop email activity.

For email marketers targeting personal email addresses, this is a particularly important statistic to consider. With Apple Mail dominating mobile usage, a large portion of your audience is likely to see AI-generated summaries first, which could impact how your emails are opened and read.

This makes optimising for Apple Mail users on mobile devices an essential part of any effective email marketing strategy.

The iPhone 17 Pro: Accelerating AI adoption

Apple’s iPhone 17 Pro, released last month, makes adopting these AI features even easier. With its faster A19 Pro chip, improved battery life, and advanced iOS 18.1 capabilities, more users are expected to enable Apple Intelligence. This means:

• A larger audience will interact with AI-generated summaries, making it more important than ever for marketers to optimise subject lines and content.
• High-performance devices like the iPhone 17 Pro allow for seamless mobile email experiences, increasing the likelihood users will read, summarise, or act on emails while on the go.

Marketers can take advantage of the device’s enhanced visuals for email campaigns, creating engaging content tailored for Apple’s ecosystem.

Recommendations for small businesses:

• Optimise subject lines for mobile: Keep subject lines short (around 20–30 characters) to ensure they display fully on mobile screens.
  
  
• Continue to craft preview text: While AI may replace it for some users, many recipients will still see it, especially on desktop.
  
  
• A/B test emails: Test different subject lines and content approaches to see what resonates best with your audience.
  
  
• Focus on deliverability: Authenticate your emails, maintain clean lists, and include unsubscribe links to ensure your emails reach the primary inbox.

Apple Intelligence and the launch of the iPhone 17 Pro highlight a new era in AI-driven email marketing. AI-generated summaries are changing how users engage with emails, and marketers need to adapt quickly.

By prioritising subject lines, concise content, and deliverability, small businesses can stay ahead of the curve and continue connecting effectively with their audience.
