Most people never keep a copy of their email, because they assume the provider has it covered or that doing it themselves needs paid software. Neither is quite true. Your mail sits on a company's servers that you do not control, so a copy in your own hands is worth making. The confusion comes from search results stuffed with tools charging for something your provider already does for free.
There are really only three routes. Picking between them is easy once you know what each does.
The routes at a glance.
- Download an export from your provider. This gives you a single file with everything in it.
- Or connect a free desktop email app, which pulls copies of your mail onto your computer.
- For a few important messages, just save each one as a PDF or print it to file.
- Move or export the downloaded mail so it is no longer linked to the online account.
- Repeat it now and then, since any copy is only current up to the day you made it.
First, why a free copy is worth having
Your email lives on someone else's computer, where access is not guaranteed forever. A forgotten password, a hack, a closed account or a provider policy change can all put it out of reach. The mail itself is fine day to day, but a copy you hold yourself is the one thing no lockout can touch.
A backup you control is the only copy that survives a lockout, a hack or a closed account. The reassuring news is that keeping one costs nothing. People think it needs paid software only because the search results are full of it, most of it charging for something your provider already lets you do free. Whether sync alone counts as a backup is covered in our guide on whether your email is automatically backed up.
Route 1: download an export from your provider
The simplest route is to ask your provider for a copy. Google accounts have a data download tool, sometimes called Takeout, in the data and privacy section. Turn everything off, switch on Mail alone, choose a format and Google builds a downloadable archive of your messages. It arrives as a standard mailbox file you can open later in a free email app.
A provider export hands you your entire mailbox in one file, which is the fastest way to a complete copy. Desktop Outlook can do the same through its import and export menu, saving a data file to a location you choose. The catch worth knowing is that these exports are a snapshot: they capture your mail up to that moment and cannot be poured back into the account later, so they are for keeping rather than restoring. What these files actually are is explained in our guide on email file formats.
Route 2: connect a free desktop email app
The second route gives you an ongoing local copy. Install a free desktop email client, the kind you add an account to, then let it fetch copies of your messages onto your computer for offline reading. Thunderbird is the usual free choice and works with almost any account. This is where one detail matters more than any other. If the app connects by sync, deleting a message in the app also deletes it online. The reverse is true too, so a plain synced mailbox follows your live account rather than protecting against it.
A synced mailbox is a mirror, not a backup, because it copies your deletions just as faithfully as your messages. To turn it into a real backup, move the messages you want to keep into the app's own local storage, which sits on your computer and is no longer tied to the server. Once they are there, deleting them online leaves your local copy untouched.
Route 3: save the few messages that really matter
Not everything needs a full archive. For a handful of important emails, a receipt, a contract, a letter you want to keep, the quickest route is to save each one on its own. Every provider lets you print a message. Choosing to print to PDF instead of paper saves it as a tidy file on your computer that opens anywhere.
For a few crucial emails, saving each as a PDF is faster than any backup system and just as safe. This is only sensible for small numbers, since doing it hundreds of times is painful, but for the documents you would panic about losing it is the simplest insurance there is.
About those "free" backup tools
A word on what the search results push. Type this question into a search engine and you will meet dozens of downloadable backup tools promising a one-click copy in any format. Some are genuinely useful, but read the word free carefully. Many so-called free versions stop after around ten messages per folder and ask you to pay for the rest, which makes them a demo rather than a free tool.
The genuinely free way to back up email is the set of native routes above, not the trial version of paid software. A dedicated tool can be worth it if you want automation or an exact format on a schedule. Our guide on how an email backup tool works explains what they do. For simply keeping a copy, though, the free routes cover it.
Keep it current and keep it safe
Two habits finish the job. First, a copy is only as fresh as the day you made it, so repeat the export every few months. Do it again after anything you could not bear to lose. Second, store the copy somewhere other than the same account, ideally on your computer plus an external drive or a different cloud, since a backup sitting inside the thing it is backing up protects against nothing.
Keep your copy somewhere separate from the account itself, because a backup in the same place fails with it. That separation is the whole point of a backup rather than an archive, a distinction our guide on archiving versus backup draws out.
