Product images don't show up in gmail & hotmail

Hello, so the product images don’t show up in gmail & hotmail (phone & desktop) but show up in Apple Mail (iPhone & Desktop) but the Logo shows up everywhere? But maybe its because I am in test mode?

Do you have an idea how to solve it? Thank you!

Hi there,

Is your image URL using the HTTPS protocol? Some email providers and browsers can prevent images from displaying when not using HTTPS for security and anti-spam reasons.

Let me know if this helps,
Cheers!
