How to Migrate Emails from One Gmail Account to Another (Complete Guide)

Why We Migrate Email from One Gmail Account to Another?

There’s rarely just one reason. It’s usually a mix of a few.

Some people build a new Gmail account because the old address is a headache. Too many spam signups tied to it over the years. A username from college that doesn’t feel like you anymore. Others are leaving a job and want personal messages out of a work account before access gets cut off.

Then there’s the organizers. One inbox for personal life, another for business or subscriptions. That split only works if the right emails land in the right place.

Storage matters too. An old account crammed with a decade of attachments gets slow and hard to search through. Moving the important stuff to a fresh account fixes that fast.

And sometimes the reason is just simple. You want to switch to a new Gmail address without losing emails you might actually need someday. Nobody wants to torch ten years of conversations just because the process looked complicated.

The goal, at the end of it, is this: transfer emails from one Gmail to another, keep everything usable, skip the busywork.

Top 04 Methods to Copy Emails from Old Gmail to New Gmail

No single method fits every case here. It comes down to whether you’re moving old messages, catching new ones, or wrangling a mailbox with years of buildup behind it.

Here’s what your real options look like.

Method 1: Use Gmail’s Built-in Import Tool (Easiest)

Google built this so people wouldn’t have to migrate by hand. It’s buried in settings, and most people never stumble across it.

Sign into the new Gmail account first. That’s where everything old will end up.

Manual Steps to Transfer Email From One Gmail to Another

1. Open Gmail and click the Settings gear.
2. Select “See all settings”.
3. Go to the “Accounts and Import” tab.
4. Click “Import mail and contacts”.
5. Enter your old Gmail address.
6. Follow the prompts.
7. Pick what data to bring over.
8. Start the import.

Gmail takes it from there.

Speed comes down to size. A modest mailbox wraps up fast. One with years of history and heavy attachments takes a lot longer, and Google won’t always give you a clear timeline for it.

One more wrinkle worth knowing. Import availability shifts depending on account type, and Google changes settings without much warning. If the option looks different than expected, or vanishes entirely, that’s why. Time to try something else.

Method 2: Set Up Auto-Forwarding for Future Emails

Sometimes old messages don’t matter to you at all. You just want new ones landing in the right place going forward. Forwarding handles exactly that.

Start in the old account.

Settings, then “See all settings,” then “Forwarding and POP/IMAP.” Click “Add a forwarding address” and type in the new one.

Gmail fires off a confirmation email. Open it, confirm the code, and head back to finish up. Enable forwarding, then decide what happens to the original message once it’s been sent along.

Quick. Almost too easy.

But here’s the catch that always trips people up. Forwarding only touches mail that shows up after you flip it on. Everything already sitting in that old inbox stays exactly where it is, untouched. Want both, new mail forwarded and old mail moved? Forwarding alone won’t get you there. Pair it with one of the other methods.

Method 3: Use a Desktop Email Client (IMAP)

Want more say over what actually moves? This is the method for that.

The idea’s simple enough. Add both Gmail accounts to a desktop client through IMAP. Once they’re connected, copy messages or whole folders from the old account straight into the new one.

The basics:

1. Turn on IMAP access for both accounts.
2. Add the old account to your client.
3. Add the new one the same way.
4. Let both mailboxes sync fully.
5. Copy folders or single messages across.

Something like this, folder for folder:

• Old Inbox → New Inbox
• Old Sent → New Sent
• Old Projects → New Projects

For smaller jobs, this works well and gives you exact control.

The trouble starts at scale. A few hundred emails, fine. Tens of thousands, and everything slows down. Connection stability, attachment sizes, sync speed, they all start fighting you. Accidentally repeat a transfer, or copy a folder twice, and now you’re cleaning up duplicates on top of everything else.

Method 4: Using Professional BreviSoft Gmail Backup Software

Big mailbox? This is usually where people end up.

BreviSoft Gmail Backup Tool exists for this exact job, handling Gmail data without forcing you into endless manual copy-paste. It’s especially handy when you’re planning a bigger move, want a backup before switching accounts, or need the data organised instead of just dumped over wholesale. The software also migrates emails from Outlook to a Gmail account in bulk.

Migrate Email from One Gmail to Another Account Using BreviSoft:-

1. Install and launch the BreviSoft Gmail Backup Tool.
2. Connect or select the Gmail account containing the required emails.
3. Provide the required account details and permissions.
4. Select the mailbox folders or email data you want to process.
5. Choose the available transfer or backup options.
6. Start the process.
7. Check the destination Gmail account after completion.

For a large mailbox, test with a small batch first. Five minutes of checking now saves you from finding a problem after the whole thing’s already moved.

This kind of tool also earns its keep anytime you need to import Gmail to another Gmail account as part of a bigger cleanup, not just a one-time switch.

The real value isn’t flash. It’s not losing an afternoon to dragging messages one folder at a time.

Manual vs. Professional Method: Key Differences Explained

Both routes get you there. The real question is how much manual grind you’re up for.

Moving a handful of messages? Don’t overthink it. Gmail’s own tools or an IMAP client will handle it just fine. But once the mailbox gets big, manual effort stops being a minor annoyance and becomes the whole problem. That’s exactly where a dedicated tool starts pulling its weight.

Conclusion

Leaving an old Gmail account doesn’t mean leaving your email history behind with it. Whether you’re trying to copy emails from old Gmail to new Gmail, just catch future messages, or deal with a genuinely large mailbox, there’s a method here that fits.

Gmail’s import feature is a solid starting point. Forwarding handles new mail without any fuss at all. IMAP gives you granular, folder-by-folder control if you’ve got the patience for it. And for bigger, messier migrations, BreviSoft Gmail Backup Tool takes the manual grind out of the equation entirely.

Before you merge two Gmail accounts into one, take stock first. Mailbox size, key folders, attachments, the stuff you genuinely can’t afford to lose. A little prep now beats a lot of cleanup later.
