Summary: Are you planning to transfer emails from Roundcube to Gmail? This blog is for you. In this blog, we will cover several methods to complete the transfer process. The manual methods include using Gmail’s “Add Account” option, Thunderbird, and Email Forwarding. We’ll also go through the reasons why people prefer to make the switch. We will also explore an automated MCD IMAP Backup Tool that is especially designed for seamless email migrations. Each method is explained in detail with step-by-step instructions to ensure quick and easy email migration.
Roundcube is a web-based email client that allows users to manage and read their emails through a web browser. On the other hand, Gmail is an email service provided by Google that stores email messages in the cloud. Users can access these emails on any device when they are online. Users often transfer their emails from Roundcube to Gmail to utilize Gmail’s advanced features and better security.
There are four methods for transferring emails from Roundcube to Gmail. The manual methods using Gmail’s Add Account option, Thunderbird email client, and forwarding method. Another one is by using a dedicated and secure tool. Users can choose either of the two methods depending on their specific requirements.
To make this method work, ensure that POP is enabled on the source email server. Also, to import Roundcube emails to Gmail mailbox, we are importing from the email account linked with Roundcube using POP3.
| Username: | abc@example.com |
| Password: | Email password |
| POP Server: | mail.example.com |
| Port: | 995 |
Limitations: This method will only import inbox emails and not the drafts, sent items folders. Manually entering the server details may lead to errors. There is a chance of loss of data while handling large mailboxes. Some of the emails may lose their attachments.
This Roundcube to Gmail migration involves linking a Roundcube account in Thunderbird. Then, add the Gmail account and drag-and-drop emails from Roundcube to the Gmail account folder.
Limitations: If too much data is transferred, then it may affect the performance of Gmail. Make sure to have a stable internet connection to fully transfer the data. The user should have some technical knowledge about setting up IMAP accounts, monitoring migration, etc.
This method is suitable when you want to transfer only a few important emails.
Limitations: There is no option to bulk forward the emails. Manually forwarding emails one by one take a lot of time. Some of the emails might lose the attachments during the process.
The IMAP Backup Tool is a powerful utility that allows efficient email backup and migration. With this tool, the user can convert IMAP emails into multiple file formats. It also allows users to transfer the entire mailbox to cloud services like migrate Roundcube to Office 365, Gmail, etc. For large-scale migrations, the bulk conversion feature is useful, making the ideal choice for businesses. Moreover, the tools’ built-in filters feature is used to target selective email types. Users can also choose to back up only the email messages by excluding attachments, reducing storage space.
In this blog, we have reviewed the most reliable methods to transfer emails from Roundcube to Gmail. While the manual options do exist, they often have some limitations and are prone to errors. For a more secure and accurate process, the IMAP Backup Tool is the more efficient tool to use. It also offers the option to batch transfer multiple emails at once, filter out duplicates, etc. Users can choose the right method as per their requirements.
