Volim Mail · Mail on this Mac
Your mail.
Ready when Wi-Fi isn’t.
Keep the mail you need on your Mac. Read it, find it and work through it offline. Volim catches up with Gmail when you reconnect.
Faster mail. Richer context.
More on your Mac.
More to work with.
When mail is kept on your Mac, folders open and search runs without a round trip to Gmail. An assistant you’ve allowed can search that same history.
Less waiting for the everyday
Results from your Mac appear first. Gmail’s results join them when you’re connected.
Better context for the next answer
More history gives AI more to refer to. It doesn’t train or change the model, and each account’s permissions still apply.
A cloud AI service always needs a connection. Offline mail doesn’t make it work offline.
Storage options
A little mail.
Or all of it.
You turn this on for each account, including the one account on the free plan. Volim shows the download size, the time it will take and your free disk space before it starts.
| Level | Messages | Attachments |
|---|---|---|
| Off | Regular browsing cache only | Not kept offline |
| Lightweight | Last 30 days | Not downloaded |
| Medium Recommended | Last 90 days | Last 30 days |
| Heavy | Last 12 months | Last 12 months |
| Full | All mail | All attachments |
What you can open offline depends on what has finished downloading. A large mailbox can take hours. Downloads pause in Low Power Mode and pick up where they stopped.
Working offline
Keep going
between connections.
Read and search
Open downloaded conversations and search inside them without waiting for Gmail.
Write now, send later
Write a reply offline and it waits in a queue. It sends when Volim is open and you’re connected again.
Organize as you go
File, label and archive while offline. Your changes are applied to Gmail when the connection returns.
Open folders sooner
Lists appear at once while Volim refreshes behind them, and nearby conversations are fetched ahead of time.
Recovery
Deleted doesn’t have to mean gone.
Recently Deleted keeps a copy on your Mac of mail removed from Gmail. Keep it for 30 days, 60, 90, or for good, and restore a message to Gmail with its original date.
The limit, plainly: a message must already have been saved on this Mac when it was deleted, and still be inside the period you chose. Volim can’t recover mail it never downloaded. Restoring needs a connection.
Local folders and transfers
Make room in Gmail.
Keep the mail.
On This Mac folders
Move messages into folders that live on your Mac. Volim downloads and checks the complete copy before it removes the message from Gmail. It stays searchable, and you can move it back.
Moved messages go to Gmail’s Trash, and the space comes back when Trash empties, normally within 30 days. After that your Mac holds the only copy, so keep a separate backup of it.
Take your mail to another account
Copy or move messages, conversations or whole labels between the Google accounts you’ve connected. Labels and original dates come along, and you can pause, resume or retry.
More than one account needs Pro. Transfers need a connection. A move removes the original only after the new copy is confirmed, and mail under a legal hold can’t be deleted through Volim.
Privacy and backup
Local storage, explained.
What is encrypted?
Downloaded message text and attachments are encrypted (AES-256-GCM) with a key for each account, kept in your macOS Keychain. Headers, subjects, snippets and the search index are readable on disk. The content is encrypted; the whole database is not.
Does this replace a backup?
No. The mail on your Mac is a working copy. Recently Deleted is a recovery window, and an On This Mac folder can become the only copy of a message. Pro includes separate .mbox backups with scheduling, optional encryption and restore.
Can I remove my local copy?
Yes, in Settings › Storage. Check your On This Mac folders first, and anything else kept only on your Mac. Nothing is stored on a Volim server.
Will every Gmail search work offline?
Offline search covers message text and the common filters: sender, subject, dates, labels, unread, starred and attachments. Full Gmail search is there when you’re connected.
