How to Seamlessly Use Calibre to Send eBooks to Your Kindle

### Send books from Calibre.app to Kindle Paperwhite and Kindle apps In this digital age, on-the-go reading has never been easier thanks to e-readers like Amazon’s Kindle Paperwhite and apps available on various devices. However, organizing and transferring your digital book collection can be daunting without the right tools. Enter Calibre—an open-source e-book management software that allows users to easily transfer and manage their e-books. This blog post will guide you through the process of sending books from Calibre to your Kindle Paperwhite and Kindle apps, ensuring a seamless reading experience. We’ll cover the creation of a GMX email account, configuring your Calibre preferences to include both GMX and Kindle emails, adding your GMX email to Kindle’s approved list, and finally, the straightforward process of sending a book to your Kindle. Let’s embark on this journey to simplify and enhance your reading adventures. #### Create GMX email account Before we can start sending books from Calibre to Kindle, it’s essential to set up an email account that supports the transfer. GMX provides a free email service that’s perfectly suited for this task. Begin by visiting the GMX Mail website and click on the “Sign Up” or “Create Account” button. Fill in the required fields with your personal information, such as name, desired email address, password, and any necessary security information. Remember to choose a strong password to maintain your account’s security. Once you’ve completed the registration process, you’ll receive a confirmation email from GMX. Open it and verify your account by clicking the provided link. With your GMX email account active, it becomes an integral tool in managing your e-books and subsequently transferring them to your Kindle. This email account acts as a bridge between Calibre and your Kindle device or app, facilitating seamless book transfers. #### Add GMX email to Calibre.app Preferences Now that your GMX email is set up, it’s time to integrate it with Calibre for book transfers. Open the Calibre application and head over to the ‘Preferences’ section. Here, you’ll find an option labeled ‘Sharing books by email.’ Click on this option to proceed with configuring the email settings. You’ll need to input your GMX email details here, which will act as the sender email for any e-book transfers made from Calibre. In the SMTP server settings, enter the GMX outgoing server details: `smtp.gmx.com` with port `587`. Ensure you enable ‘TLS’ or ‘SSL’ for a secure connection. Input your GMX username and password to complete this setup. Before exiting, send a test email to ensure everything is functioning correctly. With this step completed, your GMX email is ready to transfer books to your Kindle, acting as a conduit between Calibre and Amazon’s Kindle service. #### Add Kindle email to Calibre.app Preferences The next step involves adding your Kindle email address to Calibre’s preferences—a necessary action for successful book transfers. If you’re unsure of your Kindle email address, it usually follows the format of `[username]@kindle.com` and can be found in the ‘Your Devices’ section of your Amazon account. Note it down as we’ll need to input it into Calibre. Return to the ‘Preferences’ section in Calibre and navigate back to ‘Sharing books by email.’ Now, in the list of recipient email addresses, add your Kindle email address. This entry ensures that any book you send from Calibre is directed straight to your Kindle device or app for easy access. With both GMX and Kindle email addresses inputted, you’re setting up a clear and secure path for your book files to travel seamlessly from Calibre to your Kindle. #### Add GMX email to Kindle approved list An essential security step involves granting your Kindle the permission to receive emails from your new GMX account. Head over to the Amazon website, log into your account and navigate to the ‘Manage Your Content and Devices’ section. Here, find the ‘Preferences’ tab and click on it. Look for the ‘Personal Document Settings’ and find the section that allows you to manage ‘Approved Personal Document E-mail List.’ In this list, add your GMX email address. By doing this, you’re authorizing your Kindle to receive emails—and thus e-books—from your GMX account, ensuring that your book transfers won’t be blocked for security reasons. This step is crucial because if your GMX email is not on the approved list, any attempt to send an e-book to your Kindle will fail. With these security measures in place, you’re ready to transfer books freely and securely. #### Send a book Now that all configurations are completed, you’re ready to send a book from Calibre to your Kindle. Open your Calibre library and select the book you want to send. Right-click on the selected book, and from the dropdown menu, choose ‘Connect/share’ followed by ‘Email to…’ You will be prompted to select an email address. Choose your Kindle email address from the list provided. Upon sending, Calibre will use your GMX email as the conduit to send the chosen book to your Kindle device or app. The transfer process usually takes a few minutes, depending on your network speed and the size of the book. Once the transfer is complete, you’ll find the book in your Kindle’s library, ready for reading. This hassle-free method ensures that your cherished books are only a few clicks away from accompanying you on your next adventure. ### Summary of main points Now, let’s look at an overview of the entire process in tabular form:

With these steps, managing your e-books between Calibre and Kindle becomes an effortless task, allowing you to enjoy your book collection wherever you go.
