To help you with this task, we’ve put together the following guide that compares three different methods for transferring your emails to Gmail.

➡️  Whether your current email account uses IMAP, POP3, or Exchange, you’ll be able to find an approach that suits your situation:

What You Need to Know
Before Importing your Mails to Gmail

Before you start importing your emails to Gmail, it’s important to understand the type of email service you are currently using, as this will directly influence the method you choose for the Gmail migration.

Email services use different protocols, or sets of rules, for handling messages, and each protocol has its own characteristics that can affect the migration process:

IMAP (Internet Message Access Protocol):

Used by most web-based email services like Yahoo! or, IMAP synchronizes your emails across all devices. This means that actions like reading an email on your phone will be reflected on your laptop as well.

➡️ If your current provider supports IMAP, importing your emails to Gmail is generally very easy.


In contrast to IMAP, POP3 downloads your emails to a single device and, depending on your account configuration, deletes your emails from the mail server. POP3 can be compared to receiving physical mail – once it’s delivered, it’s only in your mailbox.

➡️ If you’re using POP3, you’ll need to ensure that your emails are still on the mail server before the email migration.

Microsoft Exchange:

Technically not a protocol but an email and calendar server, Microsoft Exchange is a staple in many corporate environments. It uses the MAPI protocol, whose proprietary nature can complicate the migration process because not all migration methods support Exchange accounts.

Knowing which email protocol your current email service uses is essential as this knowledge helps you to avoid email migration methods that probably won’t work in your use case.

How do I find out which protocol I’m using?
If you’ve added your email address to an email client (such as Thunderbird or Apple Mail), check the account settings in the email client. The email protocol of your current account is typically displayed there. Otherwise, ask your current email provider (write a support ticket or call them).

Best Ways to Import Mails to Gmail

Whether you have a handful of emails or huge mailboxes to migrate, below, you’ll find the right approach:

Method 01
Forward Emails from Your Old Mailbox

import mails: forward emails

Time required: Minutes to days (!), depending on how many messages you have.
Works with:  ✅ IMAP  ✅ POP  ✅  Exchange

Sometimes, the most basic methods can get the job done, and when it comes to importing mails to Gmail, email forwarding is about as simple as it gets.

Here’s how it works:
  1. Set up your new Gmail account.
  2. Log in to your old email account that you’re moving from.
  3. Forward each and every message you want to import to Gmail. Unfortunately, many email clients and services don’t let you do this in bulk, forcing you to forward each message individually.
  4. Go to your mailbox settings and look for a Forwarding section.
  5. Configure message forwarding so that all new emails are automatically sent to your new Gmail address.

✅  No additional tool or service required to import mails to Gmail


⛔️  Bulk forwarding is often not supported
⛔️  Very time-consuming for large quantities of emails
⛔️  Forwarded messages appear as unread in your new mailbox


This approach very time-consuming, in addition you loose the original message status (all emails appear as unread in your Gmail account). Therefore, we only recommend this method if you want to import a very small number of messages to Gmail.

Method 02
Use Gmail’s Built-in Import Tool

import mails: gmail import tool

Time required: Up to multiple days (!)
Works with:  ✅  IMAP    ✅  POP (emails need to be stored on the server)
Does not work with: ⛔️  Exchange

To make it easier for new users to move their online correspondence over to Gmail, Google offers a simple built-in import tool specifically designed for the job.

To access and use it, you need to:
  1. Sign into your Gmail account, click on the gear icon, and select the See all settings option.
  2. Navigate to the Accounts and Import tab.
  3. Click the Import mail and contacts option.
  4. Enter the email address you want to import and click Continue.
  5. Click Continue again and wait for a pop-up window to appear and show a login screen of the email service you’re importing.
  6. Agree to give Gmail access to your messages.
  7. Select what you want to import (your mail, your contacts, new mail for next 30 days) and click Start import.
  8. Wait up to multiple days for the import process to finish.

✅  Import all messages in one go
✅  Accessible directly within the Gmail settings
✅  Ability to import contacts along with emails
✅  Can keep your mailboxes synchronized for 30 days
✅  Preserves message read status


⛔️  Incompatible with Microsoft Exchange mailboxes
⛔️  The process can take a very long time (multiple days) to finish
⛔️  Can lead to duplicate messages


This built-in tool is great for those who need a more comprehensive migration of all messages and possibly also contacts, but it has several important shortcomings:

To start with, it can only import mails to Gmail when they’re stored in IMAP and POP3 accounts, making it unusable for Microsoft Exchange migrations. Depending on how many emails you’re migrating, it can take up to multiple days for the Gmail import tool to finish its job. And because the tool imports all messages under a new label, you may need to take extra steps to eliminate duplicates.

Method 03
