The Komplett guide to HTML Email Builders?

Creating professional HTML emails used to require extensive coding knowledge. Today, HTML email builders have transformed the process, enabling marketers and business owners to design stunning, responsive emails without writing a single line of code.

This comprehensive guide covers everything you need to know about HTML email builders: the top tools available, essential features to look for, and how to choose the right builder for your business.

Hva er an HTML Email Builder?

An HTML email builder is a software tool that allows you to create visually appealing, code-compliant emails using a visual interface. Instead of manually writing HTML and CSS, you use drag-and-drop components, pre-designed templates, and visual editors to construct your emails.

Hvorfor HTML Matters for Email

Unlike web pages, email clients handle HTML differently. Each email client (Gmail, Outlook, Apple Mail, Yahoo) renders HTML according to its own rules. What looks perfect in Gmail might break completely in Outlook.

This is why HTML email builders are essential:

Cross-client compatibility: Good builders generate code that works across all major email clients
Responsive design: Emails automatically adapt to mobile, tablet, and desktop screens
Consistent rendering: Templates are tested across email clients to ensure consistent display
Time savings: No need to hand-code and test every email variation

Key Components of Email HTML

Understanding what makes email HTML unique helps you evaluate builders:

Component	Web HTML	Email HTML
Layout	Flexbox, Grid	Table-based
Styling	External CSS	Inline CSS
Images	Lazy loading	Must specify dimensions
Fonts	Google Fonts	Web-safe or embedded
Interactivity	JavaScript	Limited or none

Frequently Asked Questions

Hva er the best free HTML email builder?

Brevo offers the best free HTML email builder for most users. The free plan includes the full drag-and-drop editor with all content blocks, 70+ templates, and sending up to 300 emails per day. Unlike Mailchimp, which limits features on free plans, Brevo provides the complete builder experience without cost.

For standalone builders without sending capability, Stripo offers a generous free tier with template access and basic design features.

Do I need to know HTML to use an email builder?

No. Modern email builders are designed for non-technical users. The drag-and-drop interface handles all code generation automatically. You simply place elements, adjust styling through visual controls, and the builder creates clean, cross-client compatible HTML.

However, knowing basic HTML can be helpful for troubleshooting issues or adding custom elements that builders do not support natively.

Which HTML email builder works best with Shopify?

Brevo (especially when enhanced with Tajo) and Klaviyo are the top choices for Shopify stores. Both offer native Shopify integrations that sync customer data, products, and orders.

Brevo with Tajo provides the most cost-effective solution with multi-channel capabilities (email, SMS, WhatsApp). Klaviyo offers deeper e-commerce analytics but at higher cost.

How do I ensure my HTML emails display correctly in Outlook?

Outlook uses Microsoft Word’s rendering engine, which handles HTML differently than web-based clients. To ensure compatibility:

Use table-based layouts (most builders do this automatically)
Avoid CSS properties Outlook ignores (background images, rounded corners)
Test specifically in Outlook desktop (not just Outlook.com)
Use tools like Litmus for comprehensive testing

Quality email builders like Brevo generate Outlook-compatible code by default.

Hva er the difference between an email builder and an email service provider?

An email builder is a design tool for creating email HTML. An email service provider (ESP) is a platform for sending emails, managing lists, and tracking performance.

Some platforms (Brevo, Mailchimp, Klaviyo) combine both, offering built-in email builders. Others (Stripo, Beefree, Litmus Builder) are standalone builders that export to separate ESPs.

For most businesses, an integrated platform is simpler. Agencies or teams with specialized needs might prefer dedicated builders.

How important is mobile responsiveness in email design?

Critical. Over 60% of email opens occur on mobile devices. Emails that do not display well on mobile see significantly lower engagement.

All modern email builders create responsive emails by default. The key is testing on actual mobile devices (not just preview modes) and designing with mobile as the primary viewing context.

Can I import my own HTML into an email builder?

Most email builders allow HTML imports, though support varies:

Brevo: Yes, paste custom HTML or upload files
Mailchimp: Yes, code your own or paste HTML
Stripo: Yes, import and edit existing HTML
Litmus: Designed for code editing from the start

This is useful when migrating from another platform or working with templates from external designers.

What email size limits should I follow?

Keep your emails under these thresholds:

Total file size: Under 100KB (ideally under 50KB)
Image weight: Under 500KB total
Width: 600px maximum for desktop
Length: What’s visible in 10-15 seconds of scrolling

Gmail clips emails over 102KB, which can hide important content and CTAs.

How do I create AMP emails?

AMP emails include interactive elements (carousels, accordions, live content). Support is limited to Gmail, Yahoo Mail, and Mail.ru.

Stripo offers the most accessible AMP email creation for non-developers. You design interactive elements visually and Stripo generates the AMP code.

For most businesses, standard HTML emails are sufficient. Consider AMP only if you have specific interactive requirements and your audience primarily uses Gmail.

How often should I update my email templates?

Review and refresh templates quarterly at minimum. Update when:

Brand guidelines change
Seasonal themes apply
A/B tests reveal improvement opportunities
Email clients update rendering (rare but happens)
Performance metrics decline

Maintaining a template library with regular updates ensures your emails stay fresh and effective.

Konklusjon

HTML email builders have transformed email marketing from a technical challenge to an accessible creative process. The right builder depends on your specific needs: business size, technical capabilities, budget, and marketing strategy.

For most businesses, Brevo offers the best combination of powerful building capabilities, affordable pricing, and comprehensive marketing features. Its drag-and-drop editor handles everything from simple newsletters to complex personalized campaigns.

E-commerce businesses benefit particularly from platforms that integrate deeply with their store data. Brevo enhanced with Tajo provides Shopify merchants with the data synchronization needed for truly personalized email marketing across email, SMS, and WhatsApp.
