Format Newsletter Content as Clean HTML
Write your newsletter in any editor, paste it here, and get clean HTML ready for your email platform — Substack, Beehiiv, ConvertKit, or custom HTML sends.
Newsletter writers draft content in whatever editor feels comfortable — Word, Google Docs, Notion, Apple Notes, or a dedicated writing app. When it is time to send, that content needs to be formatted in HTML for the email platform. Direct pasting often brings formatting issues that look fine in preview but break in certain email clients.
This tool extracts clean HTML from your formatted draft. The output uses standard HTML tags that render consistently across email clients — Gmail, Outlook, Apple Mail, and mobile apps.

The Newsletter Writing to Sending Pipeline
The modern newsletter workflow typically involves writing in one tool and sending from another. Writers prefer tools optimized for writing (distraction-free editors, collaborative tools, or just their favorite word processor), while sending happens from platforms optimized for delivery (Substack, Beehiiv, ConvertKit, MailerLite, or custom platforms).
The formatting gap between these tools is where problems hide. A heading that looks great in Google Docs might render as plain text in Outlook. A bulleted list from Word might have inconsistent spacing in Gmail mobile. Clean HTML eliminates these inconsistencies by ensuring the underlying markup is standard and predictable.
For paid newsletter operators (who depend on professional presentation for subscriber retention and conversion), this extra step of cleaning HTML is worth the 30 seconds it adds to the publishing workflow.
