Creating and Editing Emails in Interspire

Interspire Email Marketer includes multiple editors to help you create and customize email content based on your workflow and preferences.

These editors are used to build and modify newsletters, email templates, autoresponders, and other content types. Each editor is accompanied by a separate plain-text input box, allowing you to provide both HTML and text versions of your email for improved deliverability.

Available Editors

Interspire provides three email editors:

EditorBest ForHosted WhereKey Features
TinyMCEHTML editing, code imports, API contentLocally hostedWYSIWYG UI, full HTML access
UnlayerVisual design with structured componentsRemotely loadedDrag-and-drop interface, mobile-ready output
BuilderJSModern visual editing, self-hostedLocally hostedDrag-and-drop, inline CSS

These editors are available when creating:

  • Newsletters
  • Email templates
  • Autoresponders

In most other cases, say for exmple when creating dynamic content tags, the TinyMCE editor is used.

Choosing the Right Editor

When creating a new email or template, you’ll be prompted to select one of the available editors. Your choice depends on your workflow:

  • TinyMCE: Ideal for the WYSIWYG word processor style editor, and working with raw HTML or importing templates from external builders (e.g., Litmus, Stripo).
  • Unlayer: Best for drag-and-drop visual design with structured blocks.
  • BuilderJS: Recommended for users who want a modern visual builder that’s fully self-hosted unlike Unlayer that is remotely loaded.

⚠️ Editor selection is permanent per item. Once a newsletter, template, or autoresponder is created with an editor, you cannot change the editor for that item.

Plain-Text Version

Regardless of which editor you choose, every email can include a plain-text version as well. This version is critical for:

  • Improving deliverability
  • Supporting legacy or security-focused email clients
  • Providing a fallback when HTML cannot be rendered

See Text Editor for information on the plain‐text editor.

You can also validate your email, ensuring that it displays correctly in a variety of popular email clients.

See Validating an Email for information on checking how you email displays in popular email clients.
