Despite all the noise on social media and the constant shift in algorithms, email newsletters remain one of the most consistent, high-ROI tools in digital marketing. But if you’re just getting started or revisiting your email strategy, you might be wondering — what exactly is an email newsletter, and how do you use it effectively?
Let’s break it down from the ground up.
What Is an Email Newsletter?
An email newsletter is a recurring email sent to a list of subscribers who’ve opted in to receive updates from you. Think of it as your brand’s direct line to your audience — whether you’re sharing new blog posts, product launches, tips, event invites, or curated content.
Unlike promotional blasts, newsletters are built around value and consistency, helping you stay top-of-mind without overwhelming your audience.
What Is the Purpose of a Newsletter?
At its core, a newsletter exists to build and maintain relationships. Whether you’re a small business, an e-commerce brand, or a SaaS company, newsletters help you:
- Build trust by showing up regularly in inboxes
- Educate or inform through tips, news, or how-tos
- Drive traffic to your website, blog, or product pages
- Nurture leads toward conversion with timely, relevant content
- Stay relevant even when subscribers aren’t actively browsing your site
Newsletters work best when they focus on helping rather than selling. Once trust is built, conversions follow.
What Is a Website Newsletter?
If you’ve ever seen a popup or form on a website asking for your email in exchange for updates or a freebie — that’s a website newsletter signup.
In practice, a website newsletter is simply the subscription form or signup flow that collects email addresses, usually tied to a backend platform (like cmercury, Mailchimp, or ConvertKit) that powers the newsletter itself.
A good website newsletter experience should:
- Be easy to find (header, footer, popups)
- Communicate what value the user will get
- Respect privacy and opt-in practices
Sync with your newsletter calendar to deliver relevant content post-signup
What Should an Email Newsletter Include?
The best newsletters aren’t cluttered — they’re curated. Every edition should have a clear purpose and value to the reader. Depending on your audience and goals, your newsletter might include:
- A short intro or message from your brand
- A featured blog, article, or resource
- New product updates or offers
- Industry news or trends
- Event invites or webinar links
- Visual elements like banners or thumbnails
- A clear call-to-action (CTA)
Good newsletter designs balance visuals with scannable content. White space, hierarchy, and mobile-friendly formatting go a long way.
Newsletter Ideas to Get You Started
Not sure what to send? Here are a few newsletter ideas you can build into your content calendar:
- Weekly blog or content roundup
- Monthly customer spotlight or case study
- Exclusive subscriber-only discounts
- “Behind the scenes” brand updates
- Industry insights or thought leadership
- Upcoming event reminders
Use a newsletter calendar to map these out across weeks or months so your content stays consistent and relevant.
How to Start Your Own Email Newsletter (Step-by-Step)
Starting a newsletter doesn’t have to be complex. Here’s a simple path:
- Choose an email marketing platform: cmercury, for example, gives you a drag-and-drop editor, segmentation tools, and built-in analytics.
- Build your list: Add sign-up forms to your website, blog, and social channels. Focus on opt-ins — never buy lists.
- Define your newsletter’s purpose: What value are you offering? Who are you talking to?
- Plan your newsletter calendar: Decide frequency (weekly, monthly), themes, and content formats.
- Design your first template: Keep it on-brand, mobile-friendly, and easy to read.
- Write your content: Use a strong subject line, clear message, and 1–2 CTAs.
- Test and send: Always preview how your email looks on both desktop and mobile.
- Track and improve: Monitor opens, clicks, and unsubscribes. Refine based on what works.
Newsletter Best Practices to Keep in Mind
Once you’re up and running, consistency and quality will drive results. Here are some best practices:
- Use personalization where possible (first names, behavior-based content)
- Make your subject lines relevant, not clickbait
- Optimize for mobile — most users read emails on phones
- Don’t overload your content — less is more
- Keep a clean list — regularly remove inactive subscribers
- Always include a visible unsubscribe link (and don’t take it personally!)
