You have a number of options for sending e-mails.
|Priority||You can change the priority of your e-mail. Changing the priority to high will not cause your e-mail to be sent faster. However, this setting can let the recipient know that this e-mail contains important information.|
|Confidential||You can mark your e-mail as confidential. This function is only for informational purposes. You can use this function to ensure that the recipient does not share the contents or forwards the message to any unauthorized persons. If you send a confidential e-mail to a GMX address, it will appear in the inbox with a confidential icon.|
|Attach vCard||You can attach your digital business card to your e-mail (as a VCF file). The digital business card allows you to easily exchange personal data such as your name, phone number and address. You can edit your business cards in your Contacts settings.|
|Read Receipt||You can request a read receipt from the recipient. A read receipt confirms that your message was opened. Please note that the recipient can decline to send read receipts. There are other scenarios in which read receipts are not sent, such as when the recipient's e-mail program doesn’t support read receipts. There is no way to force a recipient to send a read receipt.|
