MailEditor

MailEditor is a visual email-building workspace that also lets you revise existing HTML and return production code. It fits teams, creators, and developers who need both layout blocks and source-level control. The strongest case is a mixed visual-and-code workflow; export quotas and externally hosted images narrow its fit for high-volume or self-contained delivery.

Overview

The drag-and-drop editor assembles responsive emails from reusable modules, while custom code editing and custom fonts provide control beyond a block-only builder. You can upload an existing HTML email, edit it visually, then download or copy the revised markup, or save it in your account for reuse. That combination is practical for organizations maintaining legacy templates as well as creating new campaigns.

Exported HTML keeps images hosted online instead of packaging them inside the file. Hosted assets can simplify reuse across campaigns, but teams that require a self-contained template bundle should choose another workflow. MailEditor says templates are the only customer content it stores; they are private by default, and it does not retain subscriber lists or contact profiles from connected services.

Key features

Visual construction and existing HTML

Pre-built content modules speed up repeated layouts, and the visual editor is aimed at responsive output. Upload-and-edit support is particularly useful when a developer needs a designer or marketer to adjust an established template without rewriting its structure. The embeddable JavaScript plugin extends that model into another application, returning updated HTML and CSS to the host product.

AI drafts and Gmail access

Describe a design prompt and MailEditor generates an editable email draft. The small allowances on Free and Starter make this a way to kick-start occasional concepts, not a substitute for a large template-generation pipeline. A Gmail add-on exposes the template library inside Gmail, so users can insert saved designs without switching to the main editor.

Exports and connections

HTML can be downloaded or copied, and ESP export connections include Mailchimp, Gmail, Klaviyo, ActiveCampaign, SendGrid, Brevo, HubSpot, Outlook Web, and Salesforce Pardot, among others. This breadth helps teams move finished designs into existing email stacks, although the number of exports depends heavily on the plan.

Security and data controls

MailEditor says browser traffic and third-party connections use TLS 1.2 or higher, with databases and file storage encrypted at rest using AES-256. Stripe processes payments, and card numbers and payment credentials are not stored on MailEditor servers. These measures suit teams with baseline security requirements, while the product's own image-hosting model remains a separate deployment consideration.

Pricing

All paid prices are annual-billing terms. Starter is inexpensive but retains the two-member seat limit and finite exports; Team is the meaningful step up for collaboration and quota headroom. Agency removes the main production ceilings and includes 24/7 priority support through Get Prime. The free tier has no published monetary price and its export, storage, and AI limits arrive quickly for active campaign work.

Platforms

MailEditor is offered as a web product, API, and extension. The API and embeddable plugin matter to developers integrating editing into another application, while the extension and Gmail add-on support users who work inside their mail environment.

Who it's for

Choose MailEditor if your team alternates between visual layout work and direct HTML editing, needs reusable templates, or exports designs into several email platforms. It is also a sensible fit for developers embedding an editor in a product. It is less suitable when every export must include locally packaged images or when a free account must support sustained, high-volume sending preparation.

Pros and cons

• Pro: Visual modules, custom code editing, and custom fonts cover both marketer and developer workflows.
• Pro: Existing HTML can be uploaded, edited visually, and exported again, reducing the cost of maintaining established templates.
• Pro: Gmail access and numerous ESP export connections fit teams already spread across those services.
• Con: Free and Starter export, storage, and AI quotas constrain frequent production.
• Con: Exported images remain online, so the HTML is not a fully self-contained package.

Alternatives

Pick Canary instead when you want a free, multi-platform email client with templates, unified inbox, and read-receipt features rather than an email design studio. Choose MJML for an open-source, MIT-licensed approach and a free REST API. Blocks Edit is an alternative for teams considering annual collaboration plans. Dragble suits users who want web, API, or self-hosted deployment with project and content-block plans. Foundation for Emails is a free web option. Mela is a broader API and web platform with site, locale, and client-seat limits on its free tier. Choose Mosaico for a free, GPL-licensed, self-hosted/web builder. PostBrix offers freemium web/API plans with project, download, testing, and storage quotas.

Verdict

MailEditor is a strong choice for small agencies, in-house email teams, and developers who want one workspace for responsive visual design, HTML revision, and multi-ESP export. Its main reason to choose it is the bridge between reusable visual modules and editable source code. Look elsewhere if you need bundled images, uncapped work on a free or low-cost tier, or an open-source/self-hosted editor.
