Two things. Organising every email you have, old and new. Not just the inbox — every folder, every year, grouped by the person you were talking to. Pulling every attachment, old and new. Every file anyone ever sent you, extracted from inside its email and gathered into one browsable library. Everything else the app does follows from those two.
Open the app, tap Add Account, and choose your provider. Gmail and Outlook sign you in through Google's or Microsoft's own page. iCloud and Yahoo need an app-specific password. That is not your normal password — it is a password you generate for one app, and you can revoke it at any time without changing anything else.
The app links you to the right page for your provider when you get there.
Because it is fetching everything, once. On a large mailbox with years of attachments that is genuinely long — hours, sometimes a night or two. It only happens once; after that only new mail arrives. The fast way through it is night mode, on the download screen. The screen goes black but stays on, and the download runs at full speed. Plug in, tap it, put the phone down. Do not lock the phone while it downloads. iOS suspends apps when the screen locks, which stops it. Nothing is lost if you do — everything already downloaded is saved, and it resumes exactly where it stopped. You can also tap Keep downloading while I use other apps to carry on in the background while you do something else. That one does not survive locking the phone either.
As far back as your provider still has, which is usually further than people expect. The app shows you the oldest date it has found while it works. One honest limit: anything your provider has already deleted is gone, and no app can bring it back. Once a message is on your phone it stays, even if the provider removes it later.
Open Files from the Mailweaver tab. Filter by type — PDFs, images, documents, spreadsheets, archives. Sort by newest, oldest or largest. Or search by filename, sender or subject. Tap a file to preview it, then Save to keep it in Files or send it on.
No. There is no Mailweaver server. Your mail goes from your provider to your device and stays there. See the privacy policy.
No. Mailweaver connects read-only. It does not send, delete, move or mark anything.
As much as your mail does — text is small, attachments are not. The app has an attachment budget you can set, and it will not fill your device: it stops before your free space runs low, and tells you where it stopped.
Mailweaver tab → Accounts → the account → Remove. You are asked to confirm twice. You can choose to keep messages that no longer exist on the server, so removing an account does not throw away mail your provider has since deleted. Deleting the app removes everything, permanently.
Email pepnexstep@yahoo.com. Tell us your provider and what happened, and there is a Diagnostics screen in the app that reports exactly what it found and what it could not — that output is the most useful thing you can send.
