Hostinger Mail
Import emails from files in webmail
Go to Settings → Email import → Import from file, upload a single .eml file or a ZIP archive containing up to 100 .eml files, and choose an inbox, existing folder, or new folder as the destination. Files can be up to 50 MB and must fit within your mailbox’s available storage. If an email can’t be read, it’s skipped while the rest continue importing.
