The best email builders in 2026, rated and compared

Overview

Topol.io is a cloud-based drag-and-drop editor built for one job: designing responsive HTML emails that drop cleanly into any sending platform. It suits marketers, in-house teams, and agencies who feel boxed in by their ESP's native editor and want a faster, more flexible way to build. There is also an embeddable Plugin version for products that want to offer email editing inside their own app.

Key features

Drag-and-drop

Fast, intuitive block editor

Templates

150+ free templates across business, e-commerce, and holiday categories

Code access

HTML blocks, merge tags, special links; export to HTML5 or JSON

AI features

Limited; the focus is design speed, not AI generation

Collaboration

Team plan with shared templates and saved blocks

Integrations

Mailchimp, HubSpot, SendGrid, Campaign Monitor, Klaviyo and more

Export

Direct to ESPs, or download HTML/JSON

Testing

Tested across major clients, including Outlook

Ease of use

One of the gentlest learning curves in this list. The interface is clean and uncluttered, and most people are building a usable email within minutes. Onboarding is light because the tool deliberately stays narrow — you are designing emails, not managing a whole marketing stack.

Pricing

Overview

A full email design platform that blends a drag-and-drop editor with direct code editing, so beginners and developers can work in the same tool. It is built for teams that produce a lot of email and want depth: a very large template library, interactive AMP support, and connections to most sending platforms. An embeddable plugin is also available for products that want editing built in.

Key features

Drag-and-drop

Visual editor paired with a built-in code editor

Templates

Very large library across many categories and use cases

Code access

Full HTML and CSS editing, plus AMP for interactive email

AI features

AI for copy, subject lines, and images

Collaboration

Real-time collaboration with shared projects

Integrations

70+ email service providers

Export

Push to ESPs or download HTML

Testing

Render testing across clients, plus built-in error checks

Ease of use

The editor is approachable, though the sheer number of features means there is a little more to explore than in a bare-bones tool. Most marketers are productive quickly; the code view rewards those who want pixel-level control. Templates and saved modules speed up onboarding for new team members.

Pricing

Overview

A no-code drag-and-drop builder for both emails and landing pages, aimed at marketing teams who want to move fast without involving developers. It pairs a huge template gallery with real collaboration and approval workflows, so several people can design, review, and ship on brand.

Key features

Drag-and-drop

Fast editor; you can start designing without an account

Templates

1,700+ templates for many occasions, plus reusable rows

Code access

Limited direct HTML editing — test against your layouts first

AI features

AI Assistant writes copy and alt text and generates images

Collaboration

Real-time co-editing, comments, and approval flows

Integrations

Export to Gmail, Mailchimp, HubSpot and more

Export

ESP export and HTML; unlimited exports on paid plans

Testing

Mobile design mode and cross-client-friendly output

Ease of use

Very approachable. The editor favours predictable, modular layouts that keep designs stable across inboxes, and you can jump in immediately. New users get to a finished email quickly, which is a big part of its appeal.

Pricing

Overview

Unlayer is an embeddable content editor for email, pages, and documents, designed to be dropped into another product as a white-label feature. There is also a standalone editor with a free plan. It is the natural pick when a development team wants to give its own users a polished editing experience without building one from scratch.

Key features

Drag-and-drop

Visual editor for email and web content

Templates

1,000+ templates, plus a stock image library

Code access

HTML output; full white-label customization

AI features

AI tools for smart text, images, and headings

Collaboration

Shared editing; note that live co-editing is limited

Integrations

API, webhooks, React, Vue, Angular, Next.js, SOC 2

Export

Export HTML or feed content via API

Testing

Responsive preview built in

Ease of use

For developers embedding it, the documentation and framework support make integration quick. As a standalone editor, the interface differs from most builders and takes a little longer to learn; some reviewers find the block-building flow more involved than rivals.

Pricing

Overview

An ESP-agnostic, no-code email platform built for teams that need to produce on-brand email at scale. Its defining idea is a modular design system — reusable, locked-down components — paired with true real-time collaboration. It is aimed squarely at larger marketing teams, agencies, and regulated industries.

Key features

Drag-and-drop

No-code editor with responsive templates

Templates

Modular component system you build once and reuse

Code access

Exports clean, client-compatible HTML; no AMP

AI features

Limited — the focus is governance, not AI generation

Collaboration

Live co-editing, inline comments, and approvals

Integrations

Unlimited ESP and CRM exports; ESP-agnostic

Export

Push to any sending platform

Testing

Responsive previews across clients

Ease of use

The editor itself is friendly, but the value comes from a structured setup. Onboarding is white-glove: the team can build your initial design system and brand setup for you, plus run live training. That makes rollout smooth for big teams, though it is more involved than a self-serve tool.

Pricing

Overview

One of the newer entrants, and it feels it — a clean, fast builder with canvas-style editing where you drag and resize elements directly rather than digging through panels. It is aimed at design-minded marketers and developers who want layout control and lean HTML without writing code.

Key features

Drag-and-drop

Direct canvas editing with a layer panel

Templates

Smaller library (around 40–90 templates) plus team blocks

Code access

Clean, lean HTML output by design

AI features

AI for subject lines, copy, images, and a production assistant

Collaboration

Team collaboration even on the free tier

Integrations

ESP export; extras like QR codes and calendar links

Export

Export limits scale by plan

Testing

Render testing across 50+ email clients

Ease of use

Modern and responsive, with sensible typographic defaults. The block system makes layouts approachable, and the editor automatically adjusts widths as you drag — which removes a lot of the usual email-design fiddliness. Most people feel at home quickly.

Pricing

Overview

Unlike the pure builders above, MailerLite is a full email marketing platform — design, sending, automation, landing pages, and forms in one place. The drag-and-drop editor is part of a wider toolkit aimed at creators, small businesses, and e-commerce stores who want everything together at a friendly price.

Key features

Drag-and-drop

Beginner-friendly editor with prebuilt blocks

Templates

150+ templates; selection is smaller than dedicated builders

Code access

Custom HTML editing on the Advanced plan

AI features

AI writing tools for copy and layouts

Collaboration

Multi-user access on paid plans

Integrations

100+ integrations: WordPress, Shopify, Stripe, Zapier, Canva

Export

Sends natively — no export step needed

Testing

Previews plus multivariate testing on paid plans

Ease of use

One of the most beginner-friendly platforms in email marketing — a low learning curve and a clean interface. The main friction is a stricter account approval process at sign-up, which can slow you down before you send your first campaign.

Pricing

Overview

Another full email marketing and automation platform rather than a standalone builder. Moosend's pitch is professional features at below-average prices, with capable automation included even on its entry plans. It suits budget-conscious small businesses, freelancers, and content creators.

Key features

Drag-and-drop

Fast, modern editor with responsive themes

Templates

130+ customizable templates

Code access

Builder-first; design is the focus over hand-coding

AI features

AI writing for subject lines and email copy

Collaboration

Team access on paid plans

Integrations

80+ integrations (fewer than some rivals)

Export

Sends natively; rich automation built in

Testing

A/B and split-flow testing inside automations

Ease of use

About as flat a learning curve as the category offers. Onboarding walks you through a few clear steps and you are sending within your first session. The fast, frequently praised live chat helps when you do get stuck.

Pricing

Overview

A modular drag-and-drop HTML email builder with a strong design sensibility. You assemble emails from a library of polished components, and the output is consistently good-looking. It suits designers, marketers, and small teams who want emails that feel crafted, with real-time co-editing built in.

Key features

Drag-and-drop

Module-based editor with a clean interface

Templates

100+ modules to combine for promo, e-commerce, and more

Code access

Generates HTML for you; export to any ESP

AI features

AI content generation (recently added)

Collaboration

Real-time co-editing with live cursors

Integrations

Mailchimp and HubSpot on higher plans; HTML to any ESP

Export

Download HTML or send through your platform

Testing

Responsive across mobile and desktop

Ease of use

Clean and intuitive, with a focus on getting a great-looking result quickly. The module approach keeps things simple. One thing to watch: a few users report a small Gmail rendering quirk that needs a minor code tweak on export.

Pricing

Overview

A codeless campaign creation platform for emails and landing pages, built for enterprise marketing-operations teams. Its real strength is deep, two-way sync with major marketing automation platforms, so designers and ops staff can build on brand and push straight into the systems they already run.

Key features

Drag-and-drop

Modular builder for emails and landing pages

Templates

Built-in template library with brand guardrails

Code access

Codeless by design; far more control than native MAP editors

AI features

AI-powered translation and localization

Collaboration

Real-time collaboration, approval workflows, roles

Integrations

Marketo, Salesforce Marketing Cloud, Eloqua, Braze, Pardot

Export

Syncs and re-syncs directly into your automation platform

Testing

Built-in render testing across clients, devices, and modes

Ease of use

Reviewers consistently call it user-friendly, and teams report building a well-designed template in just a few minutes. It is far more pleasant than editing inside a marketing automation platform directly, which is much of the point.
