Not Just Another Newsletter: Email Marketing That Actually Builds Authority

Inbox fatigue is real; you know it, your clients know it. 

In finance and investment, your clients and prospects are flooded with updates, newsletters, and thought pieces – most of which go unopened or unread.

But that doesn’t mean email is dead, far from it. 

Done right, email marketing is still one of the most effective ways to build authority, nurture trust, and stay front-of-mind with your ideal audience.

The problem isn’t the channel. It’s how most firms are using it.

Why Most Financial Firms Get Email Marketing Wrong

Too many finance and investment firms see email as a functional tool: send a monthly update, tick the marketing box, move on. 

But email should be much more than a compliance-driven nudge. It should be a strategic channel that deepens engagement and builds credibility over time.

Unfortunately, many emails end up being forgettable at best and brand-damaging at worst.

Inboxes are crowded. If your message isn’t relevant, clear, and value-led, it’s likely getting ignored.

Shift from Updates to Authority-Led Strategy

Instead of pushing out bland updates, leading firms are shifting to authority-led email strategies. 

That means treating every email as a brand touchpoint that reinforces your value, strengthens your positioning, and helps readers make smarter decisions.

Authority-led email marketing lets you use your newsletter to strengthen credibility in the marketplace. It helps:

  • Keep your brand visible in crowded markets
  • Position your team as informed, confident, and client-focused
  • Build trust long before a prospect fills out a contact form

Especially in sectors where clients are doing their due diligence online, your emails should earn their place in the inbox.

What High-Performing Finance Emails Actually Look Like

So what separates the high-performing emails from the forgettable ones?

It starts with structure and voice. 

Your message needs to land fast, feel relevant, and look credible. 

Financial audiences don’t have time for fluff – they want clarity, insight, and action.

Here’s what high-performing finance emails typically include:

  • Subject line: Specific and benefit-led. “How Q4 Shifts Could Affect Pension Allocations” beats “October Newsletter.”
  • Opening line: Get to the value fast. Name the insight or the pain point.
  • Format: Focused and digestible. One message per send.
  • Voice: Confident and human. Drop the corporate waffle.
  • CTA: A single, clear next step. Read more, book a call, download a guide.
  • Design: Clean, mobile-optimised, and branded. No need for bells and whistles – just polish and clarity.

Segment, Don’t Spam

You wouldn’t send the same proposal to an adviser, an allocator, and a retail client. 

So why would you send them the same email?

Segmentation is what makes email marketing effective. 

By tailoring your messaging to the specific needs of each audience, you increase engagement, relevance, and the likelihood of a response.

Smart segmentation includes:

  • Audience type: advisers, institutions, investors
  • Relationship stage: cold, warm, client
  • Service interest: investment strategy, pension planning, business funding

The more tailored the message, the more likely it is to resonate and convert.

Content That Actually Gets Read

You don’t need to send more emails. You need to send better ones.

That means sending content your audience genuinely finds useful. 

Content that answers real questions, clarifies complexity, or simply helps them feel more informed and confident.

Proven content formats include:

  • Market commentary with practical takeaways
  • Regulatory updates, minus the jargon
  • Adviser-focused insights (“What This Means for Your Clients”)
  • Client success stories or case studies
  • Sector-specific guides or downloadable tools

Each piece should reinforce your credibility while helping the reader do their job better.

Measure What Matters

Open rates are just the beginning. 

If you’re only tracking opens, you’re missing the real picture.

Engagement tells the true story of your email’s effectiveness. Look at:

  • Click-throughs to your website or resources
  • Replies or forwards
  • Guide downloads or booked meetings
  • Content dwell time and next steps taken

This isn’t about going viral. It’s about staying valuable.

It builds familiarity, reinforces trust, and gives prospects a reason to believe in your expertise.
