Email Marketing Trends 2026: A Strategic Guide to Success in B2B

Email marketing remains one of the most effective tools for B2B communication, with an average ROI of 36:1. In 2025 and 2026, email marketing strategies will undergo a fundamental transformation thanks to artificial intelligence, stricter personal data protection rules, and changing customer expectations. Let’s take a look at how successful B2B companies are adapting to the new reality and how you can remain competitive.

1. Hyper-personalisation and AI: the new standard

The era of generic newsletters is definitely over. In 2025, companies are switching to deep personalisation supported by artificial intelligence, which goes far beyond simply inserting the recipient’s name into the subject line.

How does modern personalisation work?

The best email marketing platforms now automatically analyse:

• Purchase and interaction history – what products the prospect viewed, what they bought when they did so
• Website behaviour – which pages he visited, how long he stayed there
• Level of engagement – which emails they open, what they click on
• Optimal delivery time – AI determines when the recipient will be most active in their inbox
• Dynamic content – different images, texts and offers for different segments

EmailMachine in practice: The EmailMachine platform allows you to set up trigger-based scenarios that automatically send emails based on specific user actions. These include registration, abandoning a shopping cart, or verifying an email address. Thanks to dynamic content, B2B companies can personalise emails according to recipient segments without having to manually create dozens of variants.

2. Automation as a competitive advantage

While in 2023 it was normal for a single email campaign to take 2+ weeks to create, in 2025 it is standard to produce one within a few hours. How was this achieved? Through automation and AI.

Key automations for B2B:

• Welcome sequence: When a new contact signs up for your newsletter, they automatically receive a series of 3-5 emails introducing them to your company, its value, and relevant case studies.
• Nurturing campaigns: Emails are only sent to those who have viewed a specific page or downloaded a white paper or e-book.
• Lead scoring: The system automatically identifies the highest-quality leads that your sales team should contact.
• Follow-up after events: Relevant materials are automatically sent after webinars, press conferences or demos.
• Win-back campaigns: Inactive contacts receive special offers with the aim of renewing their interest.

Key finding: Only 6% of B2B teams now take more than two weeks to create an email. The remaining 94% use automation and templates to save time and increase consistency.

3. Privacy and GDPR: Building trust for the long term

New data protection laws (GDPR in the EU, CCPA in the US) and readers’ growing awareness of their rights have changed the game. In 2025, the number of contacts in a database is not important – what matters is their quality.

Privacy-First Strategy:

• Collecting zero-party data: Ask your subscribers directly what interests them. Surveys in emails or preference centres will tell you exactly what you want to know.
• Double opt-in: New contacts must confirm their email address. This eliminates spam traps and guarantees quality.
• Transparency: Clearly state how you will use the data. Mention that you use AI for personalisation (if applicable).
• Easy unsubscription: Not only is it mandatory, it's also useful. Contacts who request to unsubscribe are not valuable to you.
• BIMI (Brand Indicators for Message Identification): A new standard that allows you to verify your identity in the inbox – increasing trust.

4. Interactivity: Select from Inbox

Static emails are no longer enough. By 2025, 97% of B2B marketers will be using at least one interactive element. From surveys to live inventory counts or video conferences directly in the email.

Interactive elements that work:

Email Machine supports the creation of interactive elements without the need for coding – simply add them to the drag-and-drop editor.

5. The right metrics: From open rates to ROI

Apple Mail Privacy Protection (introduced in 2021) has invalidated the “open rate” as a reliable metric. Yet there are still companies that base their strategy on opens – this is a fundamental mistake.

Metrics that truly provide meaningful information:

2-3%

Ideal Click-Through Rate (CTR)

<2%

Acceptable bounce rate

<2%

Normal deregistration rate

36:1

Average ROI of email marketing

Focus on these metrics:

• Click-to-Open Rate (CTOR): What percentage of people who opened the email clicked on something? This tells you about the quality of the content.
• Conversion rate: How many emails lead to a sales meeting or purchase?
• Revenue per Email (RPE): How much revenue does one email generate for you?
• Unsubscribe & Complaint Rates: Low numbers indicate that you are doing it right.
• Deliverability: Does it reach your e-mail inbox? (EmailMachine achieves 99% deliverability with the correct settings)

6. Czech B2B inspiration: How they do it in Czechia

E-commerce and B2B marketing are developing rapidly in the Czech Republic. The largest Czech companies, such as Alza, Rohlík and Notino, use advanced email marketing strategies:

Alza – personalisation in practice

Alza, the leading Czech e-shop, does not engage in generic communication. New customers receive a welcome series, while existing customers receive emails based on their purchase history (electronics, software, accessories). When a customer views a product without purchasing it, they receive a personalised email with a reminder and a special offer.

Notino – segmentation based on loyalty and preferences

Notino sends millions of emails every month and still achieves high open rates and low unsubscribe rates. How? Through consistent segmentation: cosmetics for women, perfumes for men, special offers for VIP customers.

7. Practical advice: How to get started or improve

Phase 1: Familiarisation with the tools (months 1 and 2)

• Choose EmailMachine (or a similar tool) – it is easy to use and has Czech support.
• Use integration or import your contacts and create your first segments (new contacts, active customers, inactive customers).
• Set up a basic welcome sequence (3-5 emails for new subscribers).

Phase 2: Automation and testing (months 3 and 4)

• Create trigger-based scenarios – anything activates an action.
• Test different items, delivery times, and contents.
• Monitor CTR and conversions, not just open rates.

Phase 3: Optimisation and scaling (5th month +)

• Deliberately experiment with interactive elements.
• Examine feedback and improve segmentation.
• Consider AI-powered copywriting tools to speed up creation.

Email Machine Tip: The platform offers integration with Shoptet and other e-commerce solutions. If you sell online, you can automatically send abandoned cart notifications, product recommendations, and post-purchase follow-ups—all without a single manual action.

Conclusion: The future of email marketing is here

Email marketing in 2025 and 2026 will be fundamentally different from what marketers knew five years ago. Automation, hyper-personalisation, interactivity, and a focus on real metrics are the pillars of success.
