Each tool serves a slightly different type of email team.

If you want flexible visual editing, reusable HTML, and greater control over existing email templates, MailEditor provides a particularly useful workflow.

1. MailEditor

Best Overall Email Builder for HubSpot

MailEditor is our top choice for marketers, agencies, designers, and businesses looking for a flexible email template builder for HubSpot.

It gives teams several ways to start an email.

You can choose a ready-made template, build an email with reusable modules, or import an existing HTML email and continue editing it visually.

This flexibility is especially useful for businesses that already have professionally designed email assets.

Instead of rebuilding a campaign every time the copy, image, product, CTA, or offer changes, teams can continue working with their existing email structure.

The MailEditor email template library covers common business communication needs.

MailEditor provides:

• Drag-and-drop visual email editing

• Existing HTML email import

• Reusable email sections

• 200+ pre-built modules

MailEditor allows those templates to remain useful.

External Email Builder vs HubSpot

Should You Use an External Email Builder With HubSpot?

An external email builder can be useful when you want a dedicated email design environment while continuing to use HubSpot for marketing operations.

The goal is not necessarily to replace HubSpot.

Instead, the two tools can handle different stages of the same workflow.

A common workflow looks like this:

1. Create the email in your preferred builder.

2. Review desktop and mobile layouts.

3. Export or move the design into HubSpot.

4. Add HubSpot personalization.

5. Configure the audience.

6. Review campaign settings.

7. Send a test email.

8. Launch the campaign.

This setup keeps HubSpot at the center of campaign execution while giving design teams a specialized workspace.

How to Choose the Right HubSpot Email Builder

The best email builder for HubSpot depends on how your team creates and manages campaigns.

Consider the following factors before choosing a platform.

1. Do You Have Existing HTML Templates?

If your company already has custom HTML templates, choose a builder that allows you to continue using them.

This can save time and help preserve valuable design assets.

MailEditor is particularly useful for this workflow because existing HTML emails can be imported and edited visually.

A marketing team can update:

• Text

• Images

• Buttons

• Links

• Offers

• Product information

• Sections

without rebuilding the complete email.

2. Do You Reuse Email Sections?

Teams that send frequent campaigns often reuse the same content structures.

Examples include:

• Headers

• Footers

• Product cards

• CTA sections

• Social media links

• Promotional banners

• Shipping information

• Legal sections

A builder with reusable modules can turn these elements into a repeatable email design system.

This can also help maintain brand consistency.

3. How Important Is Collaboration?

Consider how many people participate in email production.

A small team may only need basic sharing.

A larger team may benefit from:

• Comments

• User roles

• Approval workflows

• Version control

• Shared assets

• Team folders

RGE Studio and Chamaileon place particular emphasis on collaborative workflows.

4. Do You Need Email Portability?

Some companies use HubSpot for most campaigns but still work with other email platforms.

In that situation, portable HTML can be valuable.

Your team can maintain a reusable design library rather than recreating campaigns for each platform.

MailEditor supports workflows for HubSpot and several other popular email marketing platforms.

That can make it useful for agencies or companies managing multiple ESPs.

5. How Much Responsive Control Do You Need?

Responsive email design should be a core part of your workflow.

Subscribers may open emails on:

• Smartphones

• Tablets

• Laptops

• Desktop computers

• Different email applications

Your email builder should therefore make it easy to check how layouts behave across different screen sizes.

Pay particular attention to:

• Font sizes

• Button sizes

• Image scaling

• Column stacking

• Padding

• Navigation

• CTA placement

A good responsive email builder helps keep the message readable and easy to interact with.

6. Do You Need Custom HTML?

Custom HTML gives advanced teams more control over email design.

A visual editor can make HTML-based campaigns easier for non-developers to manage.

If developers create the original email and marketers make regular content updates, a tool that combines HTML support with visual editing can improve the workflow.

MailEditor is built around this type of flexibility.
