Converting email templates to JPEG or PNG file

Converting an Email Template to PNG

Mail Designer 365 allows you to directly export your email newsletter as a PNG file, giving you an alternative, high quality option to share your designs with your audience – for example on your website, on social media or printed.

How it works:

Let's say you've created an email template to advertise a promotion you're running in your online store. The email has gone out and now you want to export the design so you can use the visuals for other platforms.

Optimizing Your Design for Other Platforms

Mail Designer exports your design at its exact canvas width. If you are repurposing an email for social media or a website, you should consider adjusting the measurements in the editor before exporting to ensure it looks its best once uploaded.

As a guide, here are the suggested dimensions for some of the most popular platforms:

How to Check Your Dimensions Before Exporting

To make sure your design fits the recommended sizes above, you can check your current dimensions directly in the Mail Designer editor:

• Design Width: This is set in the Document settings in the sidebar. To change your design width, go to the sidebar and enter your desired pixel width before hitting export:
  
  

  Adjust the design width here before exporting to optimise for other platforms

• Height: Look at the Ruler on the left side of your canvas. The total height is determined by the number of blocks you have added.

Measurement Tip: If your design is currently 800px wide and you want it to be 1080px for Instagram (4:5 ratio), your height should be roughly 1350px. Simply resize or remove blocks until you hit that mark on the ruler!

Use the ruler to check the design height

Once your dimensions look good, go to File > Export > PNG (Desktop) to save your high-resolution design.

Which format should I choose?

PNG vs JPEG

While PNG is perfect for logos and sharp text, a JPEG is often better for repurposing your designs for social media or blog headers because it offers a much smaller file size without sacrificing visual quality.

Note: JPEG does not support transparency. If your design has a transparent background, converting it to JPEG will turn those areas white.
