Newsletters are, to this day, one of the most popular tools for building customer relationships. Despite the rise of social media and its constantly changing trends, newsletters offer something unique: direct communication with your audience. Instead of competing for attention through social media algorithms or paid promotions, you connect with customers right in their inbox. In this Katrium blog, we’ll share everything you need to know about newsletters.
Why Newsletters Matter
The digital environment is saturated with content, and businesses constantly compete for consumer attention. Newsletters provide an effective way to stand out, offering carefully curated content to an audience that has explicitly chosen to receive it. Unlike social media content that risks being lost in the algorithm, newsletters ensure that your message reaches customers directly.
The personal nature of email contributes to stronger customer relationships. Statistics show that at least 82% of people check their email every day, with most checking it multiple times a day. Opening a newsletter feels like receiving an exclusive update from a trusted source. When done right, email marketing helps businesses stay present in the customer’s mind without seeming too intrusive.

The Strategic Role of Newsletters
Newsletters support various business objectives, such as product promotion, customer retention, lead nurturing and reputation building. Consistent communication through email marketing helps organizations show expertise in their field, provide solutions to customer challenges and promote new offerings in an informative tone.
For businesses entering new markets or launching new services, newsletters can work as an effective introductory tool. They allow companies to explain their value proposition clearly. Additionally, they support audience education, gradually building interest before encouraging sales.
How Often Should You Send Newsletters?
Nevertheless, striking the right balance is key. You don’t want to appear too eager: sending newsletters too often may cause recipients to unsubscribe. Similarly, sending them too infrequently may lead them to forget your brand. Of course, the optimal frequency depends on the industry, purpose and audience preference. Many companies achieve the best results with a monthly or bi-weekly rhythm. Ultimately, tracking user engagement helps determine whether the current frequency is appropriate. If engagement drops or unsubscription rates increase, adjusting the timing or content may help restore performance.
Compliance and Data Protection
Though newsletters are a great way of customer engagement, they also come with certain obligations. When conducting email marketing in Europe, for instance, businesses must comply with applicable data protection laws, including the General Data Protection Regulation (GDPR). This means, for example, obtaining valid consent from recipients, clearly explaining how their data will be used and offering an easy opt-out mechanism.
Under GDPR, consent must be freely given, specific, informed and unambiguous. Such requirements can be met by, for example, allowing users to check a box to subscribe to newsletters. Subscribing to newsletters should be optional and reversible. After all, companies must be able to prove that the individual actually consents to receiving them. They must also regularly remove inactive contacts or recipients who withdraw consent. This is because storing contact data for email marketing purposes without sufficient justification can lead to unfortunate consequences, such as fines.

Outsourcing Newsletters to Professionals
Producing excellent content requires time, creativity and market understanding. Many businesses struggle to maintain consistency or deliver great content that truly works with their audience.
