HTML email extractor and newsletter cleaner

Go deeper

Extract HTML from an email without wasting time

An email received in Gmail, Outlook or Apple Mail often contains HTML that is hard to read: MIME headers, quoted-printable encoding, remote images, tracking links, scattered CSS and unnecessary blocks. This HTML email extractor isolates the useful content from the raw source and turns it into a clean base for auditing, cleaning or rewriting a newsletter.

A safer preview with external resources blocked

By default, external images and resources detected in the email are blocked in the preview. This avoids automatically contacting servers referenced inside the HTML, especially when an email contains tracking pixels or remote marketing images. The user can load them intentionally with the dedicated button if they want to see the full rendering.

Clean newsletter code

The tool helps remove tracking pixels, secure outbound links, truncate heavy Base64 images, inline CSS and generate a placeholder skeleton. It is useful when starting from an existing email, preparing a variant, auditing a campaign or sending a clean structure to an AI tool.

Privacy and limits

The pasted content is not sent to Outilo servers: processing happens in the browser. If you then copy the prompt into an external AI service, the content will follow that service's privacy rules. This tool helps analyze the HTML code of an email, but it does not by itself guarantee the legal compliance of a marketing campaign.
