HTMaiL: Insert HTML into email message

This extension will allow you to easily insert HTML code into the body of the message from your favorite webmail service: Gmail, Outlook, and Yahoo Mail.

HTMaiL is a Chrome extension that empowers users to effortlessly insert custom HTML code into their email messages across popular webmail services like Gmail, Outlook, and Yahoo Mail. It enhances email creation beyond basic formatting by providing an easy-to-use HTML editor with live preview capabilities.

Key features include seamless integration into webmail compose interfaces, the ability to insert HTML templates at the cursor position or selected text, and automatic conversion of CSS styles into inline styles to ensure proper formatting without style leakage. The adaptive HTML editor theme matches your OS theme for a consistent user experience. While it doesn't replace mass mailer systems and has limitations such as handling media queries or external fonts, HTMaiL uniquely transforms email composition to help create more professional and visually engaging messages.

A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
