What is a .MJML file?
A .MJML file is a type of file used to create email templates that automatically adjust to fit different screen sizes, known as responsive emails. These files are written in Mailjet Markup Language (MJML), which is a special language designed to simplify the process of coding responsive email designs. MJML looks similar to HTML and includes its own set of tags and syntax to define the content and layout of an email.
When a developer uses MJML to create an email template or specific elements of an email, such as a header or footer, the information is saved in a .MJML file. This file contains plain text that uses MJML tags to specify how the email should look. For instance, if a developer is working on a new email project in the MJML application, the main content might be saved in a file called `index.mjml`. If the email includes separate header and footer sections, these might be saved in files named `header.mjml` and `footer.mjml`, respectively. The main file (`index.mjml`) will then reference these additional files.
Although the MJML app is the primary tool for creating and editing .MJML files, developers can also use any standard text editor to work on these files. However, specific tools like Microsoft Visual Studio Code, Sublime Text, and the now-discontinued GitHub Atom offer plugins or extensions provided by Mailjet. These tools help streamline the process of editing MJML files by offering features like syntax highlighting and auto-completion specific to MJML code.
In summary, .MJML files are used by web developers to create and manage responsive email templates using the Mailjet Markup Language. These files can be opened and edited in the MJML app or any text editor, with enhanced support in some editors through Mailjet plugins.
