What Studio Does

HTML Email Builder Features

Built for the real work of creating, updating, testing, organizing, and exporting production-ready HTML email.

A visual HTML email builder made for real-world production.

Build with real email sections, table-safe spacing, responsive structure, and production controls designed for inbox work.

A section navigator for moving through complex emails fast.

Select whole sections, reorder them, duplicate them, delete them, or save the best parts as reusable blocks.

Basic blocks for the pieces every campaign needs.

Start with prebuilt preheaders, headers, heroes, text, images, buttons, two-column layouts, dividers, spacers, and legal footers.

Reusable email blocks for brand-approved sections and repeatable patterns.

Save strong sections once, then reuse them across future emails without rebuilding the same layout again.

Rich copy editing directly on the email you are building.

Edit selected text with familiar formatting tools while staying inside the visual production workflow.

Image tools for uploads, searching, and replacement.

Manage email images, swap assets, update alt text, change image links, and keep visual work moving.

Common email edits without hunting through code.

Update URLs, button labels, image widths, alt text, background images, and repeated values from one focused inspector.

Spacing and style controls that respect email compatibility.

Adjust section backgrounds, side spacing, vertical spacing, divider colors, spacer height, and two-column order safely.

Import existing HTML and make older emails easier to edit.

Bring in a full email, review suggested editable areas, and turn past work into something easier to update and reuse.

Scoped HTML editing when precision matters.

Edit selected HTML, format code, or import a full email without being trapped inside the visual editor.

Version history, undo, and restore-last-save safety nets.

Move quickly while keeping a recovery path for edits, saved versions, and earlier working states.

Email checks before the message goes out.

Run checks for builder schema issues, HTML validity, and email compatibility problems before testing or exporting.

Desktop and mobile previews for responsive email decisions.

Switch views while editing so layout problems are easier to catch before the inbox review stage.

Test sends to real inboxes with recipient controls.

Send previews to yourself immediately, manage recent recipients, and require outside recipients to confirm before delivery.

Clean HTML email export for handoff.

Copy the rendered HTML or download a ZIP package with the email and its images when the build is ready.

An email template library that stays organized as it grows.

Create templates, search by name, organize by project, edit subject and preheader details, and archive old work.

Template management for production teams.

Search templates, organize them by project, update settings, manage subject and preheader details, and archive old work from the library.

The Studio workflow

Build, reuse, test, export.

Studio is built for the practical middle ground between rigid templates and hand-coded everything.

Teams can compose emails from approved reusable email blocks, manage images, preview content, send tests, and export clean HTML for downstream systems like Pardot or other campaign tools. Serious Email's managed sending work remains private and invite-only.

Built for real production

Not another generic page builder.

Email work has its own constraints. The tool should respect them.

Marketing teams

Launch recurring campaigns without turning every request into a design or development ticket.

Agencies

Keep client templates consistent while making routine edits easier to delegate and review.

Developers

Give non-developers controlled flexibility without surrendering the underlying email system.
