Should I be concerned?

So basically what had just happened was I got an email a bit ago (from job recruiting site(?)) | have gotten emails from them before no issue but this time around there was a yellow warning I can't remember what it said but pretty sure there was an option to choose safe and all it did was make it so that the company logo appeared (I think I might have had to press the area for the logo to pop up?) My question is, was that a bad idea to do? Not actually safe? (This was on gmail btw)
