With Newsletter Glue, you have the flexibility to adjust how images appear on both desktop and mobile within the block settings.
For example, perhaps you have a logo that needs adjusted on mobile because it’s too large. First, select the image block in question and then select the mobile phone icon.

Next, set the desired width for mobile. In the case of this example, 250 pixels works perfectly.

And that’s it! Your image is now properly formatted for mobile.
