The emails sent to users for account creation, such as email address verification or password reset, can be branded with a header image and color.
Go to the App settings and select the tab Sign in. Please note that you can only change the branding when the sign in option Email is selected, as for external login this is handled by your own system. Scroll down to the section E-mails.
Logo in header: This image is shown above the email. Create a 900x300 px version of your app branding for it.
Accent color: The accent color is used for the title, for links in the email and for the footer line. Make sure this color matches your app branding.
Organization name: This name is used in the text and as a salute.
Emails will then look like this. The text itself cannot be changed.
