Email sent to your Zendesk instance has two parts that can be used for creating the ticket: the plain text part and the HTML part.
By default, Zendesk uses the HTML part of the email to create tickets and comments. This means that any rich content in emails is retained and displayed in tickets. Rich content includes full color, basic formatting options, such as bold, italic, and underline, code blocks, tables, and inline images. Special fonts and background images are not supported and do not appear in tickets.
You can disable the rich content option if you want to use the plain text version of incoming emails (which has no formatting) to create tickets instead.
- Click the Admin icon () in the sidebar, then select Channels > Email.
- Beside Rich content in email, click Enable to deselect the option.
This option should be selected by default, and you need to deselect the option to disable it.
- Click Save.
