This question came in to support:
I can’t figure out why my logos are coming out so huge on this mailing. I’m setting the sizes very small on the editor.
Some email clients (outlook, for instance) will show the images at the original size even though you set the size small when you insert them in your email.
To get around this, you should re-size the image to the size you want BEFORE you upload it. See the attached for advice on this.
