@Mack999 Generally speaking that shouldn’t happen in any situation. Can you share some screenshots of your email and how you set the logo?

It sticks out like so.

@Mack999 - Ah I see.  A few things I would try:

• Re-size the image if it’s too large (pixel width)
• Additionally, set a Max Width (in pixels) so that it would fit the mobile view.

Generally, I like to resize the image to two times the Max Width.  That will reduce the image file size and still maintain the image’s “sharpness” on high resolution devices or screens.  

Let us know if it worked!
