Spam issue regarding security on gmail app

I have been getting a ton of spam email, so I looked at one of them. I did not click anything, or download anything. However there was a spammy image with option to click on (as they always do).

Would this infect my device or the app (gmail app)? I am using an android phone. All I did was look at a spam email.

As checks, I ran the play protect from the play store. In addition, I have run several malware detection apps: Malwarebytes,Bitdefender etc. I have also looked at the installed apps and used safe mode just in case. Nothing has turned up, all of these steps show no infections.

My questions: a) is there any other check I should do? b) does just looking at an email cause an infection on the gmail app on android?
