Email newsletters are one of the most effective tools for building trust and fostering long-term client engagement. Unlike fleeting social posts or paid campaigns, a financial newsletter gives you a direct, consistent channel to communicate valuable information with clients, offering insights and keeping your brand at the forefront of their mind.

From personalised updates and market updates to timely reminders and guidance, newsletters allow you to deepen relationships. But building and maintaining an engaged audience takes work. If you’re looking to improve your reach, here are seven financial newsletter best practices that will help you expand your impact and turn casual readers into loyal clients.

1. Define your audience and your purpose

Before you press send, be crystal clear about who you are messaging – and why. Whether you’re targeting retirees, high-earning professionals, or business owners, your content must reflect their unique financial needs and concerns. For instance, tax efficiency may resonate with company directors, while estate planning tips might be more relevant for older clients.

Audience segmentation not only improves engagement but can also lead to significantly better open and click-through rates. If your goal is to grow your business through email marketing, the first step is delivering content that’s tailored, timely and purposeful.

2. Focus on quality, not quantity

There’s no rule that says you need to publish every week. In fact, sending too frequently can hurt engagement if the content feels rushed or repetitive.

Instead, focus on consistency and value. A monthly or quarterly newsletter that genuinely helps readers will always outperform a weekly one that doesn’t.

Here are a few tried-and-tested newsletter ideas for financial advisers:

• Market updates
• Tax year-end checklists or reminders
• Case studies showing how you’ve supported similar clients
• Educational explainers – for example: ‘How pension tapering affects high earners’

Delivering quality over volume will see your readers coming back for more.

Keep interested subscribers up-to-date on market news so they know where to come when they need advice.

3. Make it easy to subscribe

If growing your email subscriber list is a priority, your sign-up process needs to be easy. If it’s overly complex, it’s likely to put prospects off.

To increase email subscribers, financial services dictates you follow specific guidelines, that you are compliant. For example, that you don’t make claims that you can’t guarantee.

Include prominent sign-up calls to action (CTAs) in key locations such as:

• Home page banners or footers
• Blog and article widgets
• Service pages and contact forms
• Discreet pop-ups – though use these sparingly

Use short, succinct language that focuses on benefits, such as ‘Get professional retirement insights’ or ‘Stay informed with market updates’. Adding lead magnets, like a downloadable tax guide or financial checklist, can also give prospects a reason to sign up on the spot.

4. Promote it across channels

Even the best content needs a visibility boost. If you’re serious about growing your audience, promotion needs to become part of your ongoing marketing strategy.

Wondering how to promote a finance newsletter effectively? Leverage all the channels you already use to reach clients and prospects:

• Share signup links on LinkedIn
• Add CTAs to blog posts and resource pages
• Mention it during client calls or webinars
• Include a link in your email signature

And remember word of mouth. Encourage your current subscribers to forward the newsletter to colleagues or friends. That personal referral can go a long way in helping you expand newsletter readership organically.

5. Use personalisation to increase engagement

In financial services, trust is everything. And nothing builds trust like content that feels personal and relevant.

Use your email platform’s tools to address subscribers by name, segment recipients based on demographics or service needs, and reference topics they’ve interacted with before. Even small touches that make your emails more relevant can increase open rates and strengthen relationships, building engagement and trust, all while showing readers you understand their individual financial journey.

If you’re already segmenting clients for advice purposes, apply the same thinking to your newsletter content strategy.

6. Test and optimise subject lines

Your subject line is the gateway to engagement. If it doesn’t catch attention, your content might get lost in your subscriber’s inbox.

Instead of generic labels like ‘Monthly Update’, aim for clarity, value and intrigue. For example: ‘What you need to know before tax year-end’ or ‘Market update: What it means for you’.

Run A/B tests using your email tool to compare different approaches. This simple practice is one of the most overlooked financial email marketing tips, but it can make a big difference to open rates over time.

7. Monitor performance and adapt

You can’t improve what you don’t measure. Monitor metrics like open rates, click-throughs, and unsubscribe rates to track progress and see if your email marketing strategy needs tweaking.

Set time aside each quarter to review performance. Are certain topics driving more engagement? Are some layouts easier to digest? Use this data to constantly refine and refresh content, layout or frequency based on results.

This approach is vital if your goal is to grow newsletter audience in a sustainable, results-driven way.

Recap: When done well, a newsletter increases your brand recognition and awareness, reinforces trust, and positions you as a valuable resource in your clients’ financial journey. But consistency and creativity take time. If you’re too busy or unsure how to optimise your approach, working with a specialist in marketing for IFAs can help you achieve better results, faster.
