Digital Marketing: Newsletter Marketing

NewsletterMarketing

A newsletter that gets opened is not luck – it is the result of relevance, good timing and a clear message. We design and run newsletter programmes that activate your list rather than annoy it: segmented campaigns, tested subject lines and content your subscribers actually anticipate. No mass sends, no hollow clicks.

Challenges you'll recognise

  • Open rates are falling because all subscribers receive the same content regardless of their interests.
  • Newsletters are written on instinct and sent without a structured testing process.
  • You do not know which segments of your list actually buy and which only read.

Strategy and Editorial Planning

We plan newsletter campaigns with a clear goal per send: sales, retention, information or reactivation. Every newsletter has a prioritised core message, a clear CTA and a send time aligned to your audience – not to internal calendars.

Segmentation and Personalisation

The same message for everyone lowers open rates and increases unsubscribes. We segment your list by purchase history, engagement level, interests and lifecycle stage – and develop variants that speak to each group with relevant content.

Copywriting and Design

Subject line, preheader, headlines and CTA copy determine open and click rates. We write texts that create curiosity without deceiving, and design mobile-optimised layouts that render correctly on all email clients and screen sizes.

Testing and Optimisation

We test systematically: subject lines, send times, content order and CTAs. A/B tests run over sufficient sample sizes so winning variants are based on a robust result – not on first impressions.

Good to know

  • Subject line decides in seconds

    The subject line is the first – and often only – thing that determines whether an email is opened or deleted. Systematic testing of subject lines is the fastest lever for increasing open rates – and therefore total newsletter revenue.

  • Inactive contacts hurt deliverability

    Contacts who never open your emails lower engagement rate and sender reputation. Regular list hygiene – reactivation campaigns for inactive contacts, unsubscribing persistently inactive ones – protects deliverability and inbox placement.

  • Mobile optimisation is essential

    The majority of emails are opened on mobile devices today. Layouts that look good on desktop but are unreadable on smartphones cost clicks – and, over time, the trust of your subscribers.

Frequently asked questions

How often should you send a newsletter?
That depends on your industry and audience. B2C e-commerce often benefits from one to three emails per week; B2B audiences respond better to less frequent but more in-depth mailings. The key is that relevance justifies the frequency – too many sends without value erodes list hygiene.
Which email marketing platform do you use?
We work with Klaviyo, Brevo, Mailchimp and ActiveCampaign – depending on requirements and existing tech stack. For e-commerce we often recommend Klaviyo because of its deep shop integration. We adapt to tools you already use when switching offers no clear benefit.
How do you ensure newsletters land in the inbox and not spam?
Deliverability depends on sender reputation, list hygiene, engagement rate and technical configuration. We correctly set up SPF, DKIM and DMARC, regularly remove inactive contacts and start new sending domains with a controlled warmup process.
