This guide will explain some good methods to import EML to IMAP on Mac & Windows system, including a manual approach as well as a professional solution and you can choose whichever suits your needs and technical capabilities.

Ever Been in Such Situations?

You found some old folders of email files on your machine. These were in the EML format. Now, you wish to access these straight from your IMAP email account, but you do not know how to transfer your data.

Or you have switched from one particular email app to another, but that new app only supported IMAP, and your old email files are in the EML format. What to do now? You need to import EML files into IMAP server successfully without even losing attachments and for this you need to choose a solution that is capable enough to complete the process safely.

Why Do Users Need to Import EML to IMAP?

The necessity to import EML to IMAP comes up as EML files are local; they could easily get lost or corrupted, or even remain inaccessible in the absence of any supporting app. IMAP format tends to allow easy access to emails from all devices, anywhere and anytime!

As per Statista (Year 2024), more than 4.59 billion people globally tend to use emails as of the year 2024. IMAP tends to remain the most preferred format as it keeps email data synced across many devices.

A Practical Example

Just suppose that you had been using Windows Live Mail in your office in the past. All your work-related emails were stored in .eml files. Now, your office shifts to Gmail (which works on IMAP). To keep all your emails safe and fully accessible, you need to import EML to an IMAP server.

Situations Where You Will Need This Process the Most

Below, you will find some of the most common scenarios where such a conversion is needed:

While changing your email service provider, but wanting to keep old emails intact.
While moving from a desktop-based email application to a cloud-based service.
For forensic purposes or compliance reasons, where old email records are needed in IMAP.
To avoid any accidental loss of some email data that had been saved only on a local drive.

Manual Mechanisms to Import EML to IMAP

There are 2 main manual mechanisms that you can try:

Mechanism 1: Making Use of Thunderbird

Firstly, you must install Thunderbird.
Then, configure your IMAP account there in Thunderbird.
After that, drag & drop your EML files into the configured IMAP folder.

Pros: This is a free-to-try mechanism with no extra software required.

Cons: This mechanism is somewhat time-consuming. It also works poorly if you need to import EML to IMAP in bulk, and there is also a risk of data loss.

Mechanism 2: Making Use of MS Outlook

First of all, you must open MS Outlook.
Now, you need to configure your IMAP account.
After that, you require importing EML files one by one.
Then, you have to sync with the IMAP server.

Pros: Such a mechanism works pretty well for a small number of emails.

Cons: This has a complex setup, which needs Outlook, and it is also not suitable for bulk conversions.

Manual Mechanisms Are Not Always Workable!

Such mechanisms are not suitable for big batches of EML files.
There are higher chances of missing email attachments and/or metadata.
Such ways need you to have sound technical know-how.
Such processes are very time-consuming.
