EDITOR
EML Editor
Open an EML file, update sender name and email, set a custom Reply-To, enable High Priority when needed, edit the body, manage attachments, and download a rebuilt EML file.

Sender name, sender email, To, Cc, Reply-To, Subject, Priority
Output

MESSAGE WORKSPACE
Edit message headers and content without leaving the browser
This editor is designed to stay practical. You can update sender name and email separately, set a different Reply-To address, turn on High Priority, optionally refresh the date headers before download, edit plain text or HTML, and rebuild the file in one place.
UPLOAD
Source file
Load a single .eml file to populate the editor with headers, body, and attachments.
Load .EML into editor
Drop an .eml file here or choose it manually. The file is parsed in the browser and prepared for editing.
Current file
No file loaded
HEADERS
Message headers
Update sender and recipient fields, keep or remove Cc and Reply-To, enable High Priority when needed, and optionally refresh the date headers before export.
Rebuilt From header
No sender email set
Reply path
Replies will use the sender address
When enabled, the editor refreshes the Date, Received, and Delivery-date headers just before the rebuilt EML is downloaded.
BODY
Editing workspace
Switch between plain text, HTML source, and a safe HTML preview.
ATTACHMENTS
Attachment manager
Review original attachments, remove what you do not need, and add new files before rebuilding the EML output.
No attachments loaded
Attachments from the message will appear here. You can also add files manually before downloading the rebuilt EML file.
