Upload your Gmail Takeout export and get a complete breakdown of your inbox: who's flooding it, which newsletters you ignore, and a step-by-step plan to fix it.
Important: The default "Include all messages in Mail" setting exports All mail including Spam and Trash, which is often 10–20+ GB. Mail Zero caps Takeout .zip uploads at 150 MB and extracted .mbox files at 500 MB.
Option A — Inbox only (recommended): Click "All Mail data included" next to Mail to open the label dialog.

In that dialog, uncheck "Include all messages in Mail", then uncheck all labels and check only Inbox. This gives a much smaller file that still covers what most people care about.
Option B — Export all mail:Leave "Include all messages in Mail" checked if you want full history including Sent, Archived, etc. Expect a very large download; upload the .mbox file inside the zip (not the zip itself), up to 500 MB.
If Google splits your export into multiple files, upload any one of them — each part works on its own.
