FAQ

Questions, answered.

Can I import thousands of EML files?

Yes. Drop the folder; the import holds the messages in memory while it writes, so very large imports need about four times their size in free memory.

Is my file uploaded?

No. The engine runs inside your browser tab and reads the file from your disk. Results are written to your browser's private storage until you save them. Nothing is sent to a server.
