Hi Laidetec,

Thank you for reaching out to Jotform Support. I am currently using a translation to provide assistance, but if you want to get assistance in Spanish language, we can forward your request to our Spanish Support Team, but please note that it may take longer to receive a response.

Customizing the background image of the Notification Email is easy to do. Let me walk you through it:

• In Form Builder, in the orange navigation bar at the top of the screen, click on Settings.
• Under the Emails tab on the left side of the page, hover your mouse over the Email element you want to edit, and click on the Pencil icon.
• In the window that pops up, click on Table Properties in the black menu bar at the bottom.
• Add the below line of code in the Style field.

background: url(Add_the_backgorund_image_URL_here)

• Save it.

Reach out again if you need more help.
