My Logo is Blurry in my newsletter

Hi there @Leslie Nicole,

Thanks for posting to the Community!

One of the prevailing standards for improving the crispness of a rendered image in an email is indeed to insert an image 2x the desired size and then reduce the image size within your template. There are two ways to approach this:

1. Insert a large, crisp version of your image into your template, then click Edit Image and resize to your preferred dimensions
2. Insert a natively larger image (i.e. 600px wide) and display at a smaller size (i.e. 300px width) using CSS; to take this approach, you'll need to insert your image into a text block and adjust the CSS source code.

Could you explain why this process might not work for you? Is there some graphical error that occurs when resizing or some formatting issue? 
Here is a great resource to help you troubleshoot your desired logo quality. 

All the best,

Alex
