Your problem
My problem is:
I have a SocialElement block on the end of the newsletter (using the GrapeJS builder). Now when passing through Mail Tester, I get the complaint that the alt text of the social icon images is not defined. Is there a way to define the alt text for those social elements? Or do I need to change it to an image block to be able to do that?
