Get every attachment out of your mailbox
One .zip archive, sorted by folder. Read-only: your mailbox is never changed.
How it works
- Enter the credentials of the mailbox to scan — address, password (or app password) and IMAP server settings.
- Decide whether to include embedded images — left unticked, the archive skips signature logos; ticked, it contains absolutely everything.
- Check the summary — MailSync tests the connection and estimates the volume to scan, then you start the extraction yourself.
- MailSync goes through every folder, read-only — for each message it takes a copy of the attached files and adds it to the archive.
- Download your .zip archive — a completion email is sent if you provide an address; the archive stays available for 48 hours.
One directory per folder: the archive mirrors your mailbox tree, and a message's attachments land in the directory matching its folder. Two files with the same name in the same directory are renamed ("invoice.pdf", "invoice (2).pdf"): nothing is overwritten, nothing goes missing.
Read-only: your mailbox is never changed at any point. Messages keep their attachments; the tool merely copies them. No message is marked as read.
Use cases
- Gathering your accounting paperwork — invoices, expense claims and statements received by email over a whole year, handed over in one go instead of reopened one by one.
- Collecting the documents of a project that's wrapping up — quotes, plans, contracts and photos exchanged along the way, archived outside your mailbox once it's closed.
- Finding a file when you no longer remember who sent it — once every attachment sits on your disk, your operating system's search is far more effective than your mail client's.
- Preparing a mailbox clean-up — putting the files somewhere safe before sorting through old, heavy messages, knowing nothing will be lost.
- Archiving before an address is closed — changing host, ending a subscription or leaving an employer: the documents come with you even if the mailbox disappears.
What this tool doesn't do
- Extraction works over IMAP only: mailboxes reachable solely through POP3, or through a closed proprietary Exchange connector, cannot be scanned with this tool.
- The archive holds the attached files alone, sorted by folder: it does not contain the message text or its headers. If you want to keep the messages themselves, use the mailbox backup tool instead.
- Images embedded in message bodies (signatures, logos) are skipped by default. That's a deliberate choice: on a real mailbox they run into the hundreds and are almost never useful. The form's checkbox lets you keep them if you need to.
- The tool deletes nothing: it does not strip attachments from your messages to free up space. Your mailbox comes out exactly as it went in.
- The archive stays downloadable for 48 hours after the extraction finishes, then it's permanently deleted from our servers.
- Beyond 5 GB of mailbox scanned, finishing the operation requires a one-off payment or the Premium plan, which removes the volume limit. That threshold is the same for everyone.
Frequently asked questions
How is the archive organized? +
You get a .zip archive that mirrors your mailbox tree: one directory per IMAP folder, holding the attachments of that folder's messages. It's the most useful layout in practice — you usually remember which folder a document was in, whereas the sender can be found by searching your mail client.
What happens if two attachments share the same name? +
Nothing gets lost. Within a folder, a second attachment called "invoice.pdf" becomes "invoice (2).pdf", the third "invoice (3).pdf", and so on — the way your browser does it. The comparison ignores case, so nothing disappears when you extract the archive on Windows or macOS.
Are signature images included? +
Not by default: images embedded in the message body (company logo, headshot, divider) are skipped, otherwise your archive would fill up with hundreds of pointless "image001.png" files. If you need them, tick "Also include embedded images" before starting. Images sent as real attachments (a photo, a scan) are always included, with or without that option.
Is my mailbox changed? +
No. The connection is read-only: no message is deleted, moved, or even marked as read. The tool only reads your messages to take a copy of their attachments; the original messages keep theirs.
How long does the archive stay available? +
The archive is downloadable for 48 hours after the extraction finishes, then it's permanently deleted from our servers. After that, you'll need to run a new extraction.
How much volume is covered for free? +
Extraction is free up to 5GB of mailbox scanned. Beyond that, the first 5GB are processed for free, then you finish the operation with a one-off payment or by switching to Premium, which removes the limit. The threshold is about the volume scanned, and it's the same for everyone.
Are my credentials kept? +
No. Your IMAP credentials are encrypted for the whole duration of the operation, then erased as soon as it finishes. If you're signed in to your MailSync account and chose to save the mailbox, only that one is kept (encrypted) so you don't have to retype credentials; you can delete it at any time.
Which providers are supported? +
Any provider offering standard IMAP access: Gmail, Outlook/Microsoft 365, Yahoo, iCloud, OVH, o2switch, and the vast majority of hosts. You need the credentials and the IMAP server settings (address, port, SSL).
