If you want to import IMAP emails into Gmail, a simple approach is to do it in two steps. First, create a complete backup of your IMAP mailbox in PST format using the MailsDaddy IMAP Backup Tool, which securely exports emails while preserving folders and message properties. Once the PST file is ready, use Google Workspace Migration for Microsoft Outlook (GWMMO) to import the PST file into your Gmail account. This method helps maintain your original folder structure, email formatting, attachments, and metadata throughout the migration. It is a reliable option for users who want to move their IMAP mailbox to Gmail without losing important data.
Users can consider Shoviv IMAP to IMAP Migration Software. It preserves folder hierarchy, read/unread status, and other metadata during the transfer, and supports batch migration for multiple accounts at once. Users can apply the filter for the desired data selection and automate the migration process using the scheduler. It is boosted with the incremental migration facility to resume migration and avoid item duplication. It can be a quicker route if you want a direct IMAP to Gmail move rather than going through the backup and import process.

The easiest way to import IMAP emails into Gmail is by adding the IMAP account to Gmail via Gmail’s Mail Fetcher or by migrating the mailbox via your email client. But it works only when the OST file is accessible through an active Outlook profile. This is fine for smaller mailboxes that don’t need to be migrated in full.
Limitation: Gmail’s import options are limited. They may not move every folder as you would expect, can take a long time for large mailboxes and don’t scale well if you need to move many IMAP accounts.
For larger migrations, an IMAP backup method is often more reliable. For example, DataVare IMAP Backup Tool enables downloading IMAP mailbox data to the local system in PST and other formats. Once you have backed up the mailbox, you can import the data using the method that best suits your Gmail migration workflow. This is especially useful if you want to keep a local copy of your emails before making any changes to the original IMAP account.
If you’re moving a small IMAP mailbox, Gmail’s built-in Check mail from other accounts (POP3) or adding the IMAP account in an email client can work, although these methods may not preserve every folder exactly as expected and can be slow for large mailboxes.
If you need to migrate multiple IMAP accounts or want more control over the process, a dedicated migration tool can be helpful. For example, the Aryson IMAP Migration Tool lets you migrate emails directly from IMAP to Gmail while maintaining folder hierarchy, attachments, and email properties. It also supports bulk migration and filters, which can be useful for larger migration projects.
The best approach depends on the size of your mailbox and whether you need a one-time migration or ongoing access.
I’m planning to consolidate a few old email accounts into my primary Gmail account, and most of them are hosted on IMAP-enabled servers. I know Gmail has a mail fetch option, but it seems limited, especially when dealing with multiple accounts, large mailboxes, or preserving folder organization.
Has anyone here imported IMAP emails into Gmail using a dedicated migration tool instead of the built-in Gmail importer?
While searching for options, I came across the MacSonik IMAP Backup Tool, and it looks like it supports direct migration from IMAP accounts to Gmail. What caught my attention is that it also works with Office 365, Google Workspace, and even IMAP-to-IMAP migrations, so it seems useful if you need to move data between different platforms.
Another thing I liked is that it can process multiple mailboxes in one go without any mailbox size restrictions. For organizations or anyone managing several email accounts, that sounds much more practical than exporting and importing accounts one by one.
I also noticed it lets you preview mailboxes before starting the migration, so you can select only the folders you actually want to move instead of transferring everything. It apparently maintains the original folder hierarchy as well, which is important because I don’t want my folders to become a mess after the migration.
One feature that seems especially useful is the ability to avoid duplicate emails by comparing fields like Subject, From, To, and Body. That could save a lot of cleanup time after importing into Gmail.
Besides Gmail migration, the tool can also back up IMAP emails into formats like PST, PDF, MBOX, EML, MSG, CSV, DOC, and DOCX, which is a nice bonus if you ever need an offline archive.
Importing IMAP emails to Gmail is possible manually, but it often becomes slow and complicated when dealing with large mailboxes or multiple folders. A more reliable approach is to use an IMAP migration tool. I recently used the Softaken IMAP to IMAP Migration Tool, and the process was straightforward. After installing the software, I entered the source IMAP account credentials and then logged in to my Gmail account as the destination. The tool displayed all mailbox folders, allowing me to preview emails and apply date filters for selective migration. Once I clicked Start Transferring, it securely moved emails, attachments, and folder hierarchy without altering the original data. It supports Gmail, Office 365, iCloud, cPanel, and many other IMAP servers, making email migration quick and accurate.
