I have ad blocker to block deceptive ads that appear like an unread email
I understand ads generate revenue and happy for them to be used, but you need to not impede the user experience or use deceptive means to generate clicks. Ads need to be clear that they are an ad so people can choose to click on it, using deceptive means to trick people into clicking is just wrong and shows your true motivation - not to have a good mail platform, but to make money.
Now you go and put a splash screen up to force us to turn off an ad blocker that is blocking the deceptive ads you put up. Turn off the splash screen, remove deceptive ads and take a long hard look in the mirror!
