Best Email Builder Tools in 2025: Features & Pricing Compared

Did you know that the world exchanges more than 251 million emails every minute? It’s wild to imagine — millions of conversations, reminders, updates, and decisions all happening in real-time. Leading this global surge is the United States, which sent an average of 9.8 billion emails daily in August 2025. That’s not just a number; it’s proof of how deeply email is woven into our daily lives.

With email usage at this scale, having the right email builder is more important than ever. The right tool doesn’t just help you create beautiful emails — it ensures efficiency, scalability, and smooth integration into your workflows.

In this blog, we’ll cover the key features to consider before choosing an email builder, explore the best email builder tools in 2025 — including Unlayer, Beefree, Stripo, Topol.io, Postcards, and Chamaileon — along with their features and pricing, and discover why Unlayer stands out for teams seeking customization, scalability, and developer-friendly integrations. 

What Features to Consider Before Choosing an Email Builder

A good email builder needs to be more than just a drag-and-drop tool. It must strike a balance between ease of use, creative flexibility, and developer-friendliness, while supporting the growing demands of businesses and SaaS platforms. 

Here are the key factors to consider:

1. Ease of use for non-technical users

Your email builder should make designing campaigns feel easy—not like a technical project. Prioritize one with drag-and-drop blocks, attractive templates, real WYSIWYG editing, and simple inline styling, so anyone on your team can create polished emails quickly.

But real ease of use goes beyond “pretty UI”: it means that teams can build effectively without developer bottlenecks yet still maintain design consistency. What’s more, user onboarding should be straightforward, and low-fi changes (color tweaks, font updates, image swaps) should not require technical intervention.

2. Full customization and design precision

It’s tempting to think “drag-and-drop is enough,” but many real-world email needs go beyond what default components offer. A quality builder should allow full control over layout, spacing, fonts, colors, and assets. 

For more advanced teams, the ability to open the underlying HTML or JSON structure — or to define custom blocks/modules — is critical. This gives you full control over every detail of your design, so you can create templates that truly reflect your brand and look great in any email client. Additionally, reusable blocks and template inheritance make it easy to maintain consistency across your campaigns while allowing designers to experiment and iterate quickly. 

3. Developer-friendliness & embeddability 

For SaaS platforms, CRMs, or enterprise software, developer support is non-negotiable. A solid email builder should easily embed into your app and offer a powerful SDK or API, so your team can integrate, customize, and extend it exactly how you need.

Developers should be able to extend functionality, add custom blocks or tools, and manage workflows programmatically. This ensures that the email editor is not just a standalone tool but a seamless part of a larger product ecosystem.

4. Responsive design & cross-client compatibility

With a variety of devices (mobile, tablet, desktop) and email clients (Gmail, Outlook, Apple Mail, etc.), responsiveness isn’t optional — it’s essential. The builder should automatically generate responsive layouts, ideally offering built-in previews for the most popular clients and devices.

Email previews should closely match real-world delivery, so teams don’t get surprised by broken layouts. Bonus if the tool offers testing tools (or integrates with third-party preview/testing services) to catch rendering issues before sending.

5. Collaboration and workflow tools

Behind every campaign, there’s usually a team of marketers, designers, writers, and sometimes developers, all working together to bring it to life. A great email builder makes teamwork effortless with real-time co-editing, comments, and version control, so everyone stays on the same page.

Role-based permissions enable you to control who can edit, comment on, or approve emails, keeping your team aligned and projects moving smoothly. Additional features, such as task assignments, notifications, and activity logs, help keep projects organized, prevent mistakes, and expedite delivery. In short, collaborative editing turns an email builder into a team platform.

6. AI-powered assistance

AI capabilities are becoming a differentiator in 2025 and beyond. A study conducted by SurveyMonkey on US workers in 2024 found that 51% use AI tools to optimize content, from email campaigns to search engine optimization. 

Modern email builders should offer AI-powered features that suggest layouts, enhance copy, optimize images, and personalize content for different audiences. AI-powered features save time, reduce errors, and enhance creativity, allowing teams to focus on strategy rather than repetitive design tasks.

7. Pricing & budget friendliness

When it comes to pricing, cost often becomes a deal‑maker or deal‑breaker — so the best email builder should come with a clear and transparent pricing model. Whether it’s a flat subscription, tiered plans, per‑user pricing, or usage‑based billing, what matters most is that you know exactly what you’re paying for. 

A well‑structured pricing plan should align with your team’s size and scale — whether you're a small startup or a growing enterprise — and offer room to scale up (or down) as your needs change. The builder should strike the right balance between price and value, giving you features, performance, and support that truly justify the cost.

8. Security & data protection 

A recent cybersecurity incident exposed over 183 million email passwords, including tens of millions linked to Gmail accounts, underscoring the vulnerability of email accounts. Thus, security must be your top priority when selecting an email building tool.

The right tool keeps your data safe with encrypted storage and secure transmission, while following standards like GDPR or CCPA. Role-based access ensures only the right people can view or edit sensitive data. Additional features, such as audit logs and two-factor authentication, not only provide an extra layer of protection for your emails but also help you stay compliant and avoid costly penalties.

9. Performance and scalability

There’s nothing more frustrating than an editor that lags or crashes mid-design. A fast, reliable email builder keeps your team in the flow, letting them focus on creating campaigns instead of troubleshooting issues. Even with large projects, everyone stays productive and on track.

Scalability is just as important: your tool should grow with your team, whether it’s a handful of users today or thousands of users across a SaaS platform tomorrow. In short, a high-performing builder makes email creation seamless, smooth, and stress-free, no matter how busy your operations get.

10. Documentation & support 

Even the best email builders can encounter issues—such as bugs, rendering problems, or complex integrations. That’s why good documentation and support are essential. Clear guides, tutorials, and step-by-step resources help your team get started quickly and troubleshoot problems on their own.

Responsive customer support ensures any issues are addressed fast, keeping campaigns on schedule. Together, these resources make your email builder more than just software—they make it a reliable partner your team can depend on.
