How do I migrate emails to my Mailfence account?

Note: Before you migrate emails to your Mailfence account, create a backup. This will allow you to avoid any possible data loss during migration process.

For small volume of emails:

If emails to be migrated are only a few (e.g., 10-25):

migrate-to-mailfence
Settings -> Messages -> External addresses
  1. Connect your External account via IMAP to Mailfence web-interface.
  2. Once done, drag-and-drop emails from your External account into your Mailfence account (folders cannot be copied/moved, only emails can be copied).

If emails to be migrated are in .eml format and total size is less than 50 MB:

migrate-to-Mailfence

To migrate medium volume of emails to Mailfence:

If the total size of emails to be migrated is more than 50 MB, but less than a couple of GBs, then use an IMAP client.

1. Install a desktop email client, such as Outlook, eM Client or Mozilla Thunderbird.

2. Configure your External account (from which emails need to be migrated) using IMAP protocol, in the email client. This will require IMAP to be supported and enabled in your External account.

3. Configure your Mailfence account using IMAP protocol, in the email client.

Both accounts, from which emails have to be migrated From and To, should be configured using IMAP protocol (other protocols, e.g. ActiveSync, will likely not work).

At this point, you can drag-and-drop emails or folders from your External account to your Mailfence account, in the email client. However, we do not recommend this due to the possibility of losing emails during the potentially long import process due to connectivity issues. We therefore recommend you to follow step 4.

4. Export your External account emails and import them in your Mailfence account, in the email client e.g.,

Using Outlook:

Make sure the synchronization of your external account is done.

4.1 Create a backup of your External account (in .pst format):

4.2 Then import this backup file in your Mailfence account:

Once done: Make sure to run Send/Receive All Folders function, to synchronize all of the imported emails with Mailfence server. This can take some time depending on the number of emails to synchronize. If specific folders (e.g., recognized as tags) fail to synchronize, close and re-open Outlook client, then run Send/Receive All Folders function again.

OR

Using Thunderbird (folder by folder):

Install following plugin:

4.1 Export emails from your external account:

  • Select concerned folder (to be exported) from your External account.
  • Right-click and click on ImportExportTools NG -> Export all messages in the folder -> EML.
Export all emails from selected folder into EML format

4.2 Import emails in your Mailfence account:

  • Select concerned folder (to store imported emails) in your Mailfence account.
  • Right-click and click on ImportExportTools NG -> Import messages -> Select all emails (in. eml format) from your device to import.
Import all emails into selected folder

Migrate large volume of emails to Mailfence:

If the total size of emails to be migrated is more than couple of GBs, then contact our support.

Migrating tags/labels is not possible. In some cases however, you can add your External account (e.g., Gmail) to an email client program and recuperate tags/labels. Thunderbird for example (via IMAP) will recognize google tags as folders. You can then move those folders to your Mailfence account via IMAP using the same client program (while avoiding possible email duplications).

Should you have any questions, please send us an email to support@mailfence.com (PGP key).
