Problem statement
Some of the images in the verification email template are not getting loaded on the end-user’s inbox, and this is pretty random. They are SVG images.
Cause
Depending on the email provider, some providers block images from appearing.
Solution
This issue is not on the Auth0 side and is more related to the level of support each IMG type has in different email platforms.
This website states that SVG images aren’t fully supported across all Email platforms:
To fix this, you’ll need to change your image type to one fully supported, such as PNG format.
