Hi there @8046allan, 

Welcome to the Community! Happy to help! 

The dark background on your Gmail screenshot leads me to believe this  is a dark mode issue! 

Dark Mode can be challenging to design for because inbox providers like Gmail & Outlook, as well as email applications (Apple Mail, Android apps, etc.) all handle Dark Mode differently. Some email clients will invert colors, while others will simply change all colors darker. Ultimately, dark mode changes are rendered once the email is already compressed, sent out of Klaviyo, and exists within the inbox of the email client. Because the changes occur once the email has already been sent out of Klaviyo, there are a limited number of changes you can make within Klaviyo to alleviate dark mode rendering, but there are optimization tactics and best practices I’ll share below to check out as well as the documentation I linked above! 

All that said, I know that dark mode can be frustrating as it decreases control over the way your email displays in a recipient's inbox! It's important to keep in mind that all recipients using Dark Mode have selected this setting intentionally, and to circumvent the dark mode setting would go against their preferences. Here are some additional resources to help learn more!

Hope this helps!
