Email Newsletters vs. Substack

In a time when attention is more expensive than ever, the humble email newsletter has made a comeback but not in the way you might expect. We ran a Google Trends analysis (past 5 years, worldwide) comparing the traditional term “Email Newsletter” against the booming interest in “Substack”, and the results are impossible to ignore.

Key Insight: Newsletters Are Becoming Platforms, Not Just Tactics

While “email newsletter” as a term has remained relatively flat in search interest, Substack has exploded, especially in the past 12 to 18 months. This is not just about one brand. Platforms like Beehiiv, Kit, and Ghost are riding the same wave.

What is happening here isn’t just a rise in tools. It’s a shift in how people perceive newsletters.

They are no longer just marketing campaigns.

They are personal brands. Media properties. Recurring revenue channels.

What This Means For Marketers:

If you are a marketer, here is why this matters:

1. The newsletter is now part of your brand DNA
   Your newsletter is no longer a monthly blast with product updates, it is a chance to build trust, voice, and community. People want realness, not just retention loops.
2. Substack-style expectations are reshaping email
   Clean layouts, conversational tone, and value-first content are becoming the norm. Your email tech stack should reflect this shift, whether or not you use Substack itself.
3. Personal branding drives growth
   Audiences are connecting with faces behind brands, not just brand logos. If your founder, CMO, or subject matter expert is not front-and-center in your newsletter strategy, you are likely missing out.

Take Action Now

Here is how you can act on this trend today:

• Audit your newsletter, is it a product update, or a story worth reading?
• Evaluate your email tools, are you locked into marketing automation, or do you need creator-style flexibility?
• Encourage team members to build an individual newsletter, then syndicate the best content to your audience.
• Explore platforms like Beehiiv or Kit that give you hybrid power: automation meets personal storytelling.

Final Thought:

Do not Just Send Emails. Build a Media Engine.
Platforms like Substack signal something bigger than tech, they are showing us that audience = asset.
