You can write HTML and text-only e-mail in your GMX mailbox. Your mailbox is set to the HTML e-mail format by default. Using the Format button, you can switch from HTML to text-only e-mail for an individual e-mail. If you want to send a text-only e-mail by default, you can change your sending options.
If you write an HTML e-mail, numerous design options are available: You can adjust the typeface of the e-mail, paste an image into the body or use stationary templates. You can also check the spelling in your e-mail. You can find all the design options and the spell check in the bar above the message field.
A text-only e-mail makes sense in the following situations:
If you want to send a link by e-mail, enter the website (for example https://www.gmx.com). When you send the e-mail, the written website automatically turns into a link. However, you cannot click the link while writing the e-mail.
