Extract text from Apple Mail stationery files (MAILSTATIONERY)
To convert MAILSTATIONERY stationery files to another format, you need Apple Mail or other Web software.
To convert other file formats to the "Email Template Package" file type, you need software like Apple Mail or a similar tool.
The .mailstationery file is a proprietary email template package used exclusively by Apple Mail on macOS. These files store predefined layouts, background images, and text formatting for outgoing emails.
While native to Apple devices, this format has severe limitations. It is completely proprietary and cannot be opened directly in cross-platform email clients like Microsoft Outlook or webmail interfaces like Gmail. Windows users who receive these files cannot open them without specialized tools because macOS treats them as single files, while Windows sees them as standard folders containing scattered assets.
Users typically need to convert .mailstationery files to access the internal design. The best target format is standard HTML for the layout, combined with extracting the image assets (PNG or JPG). Repacking everything into a ZIP archive is the most practical way to share the template with non-Mac users. Converting to EML or OFT is also recommended for importing the design into other email software.
Because this is a closed, ecosystem-specific format, standard online converters often fail to process it. Only the original software can natively read the package.
