Email Kit is rigorously tested on the most common email clients.


Images are a great way to enhance the design and help provide context in supporting the content in your email. Below are the most common types of images to add in your email:


Hero images are used to draw attention to the primary action or content. They are generally found at the top of the email.


Thumbnail images support secondary content by adding context to the title or description.


Brand images such as a logo are usually located in the header and/or footer of the email.


Avatar images are used to represent a user such as a status update or testimonial.


Icons are used to supplement text in order to help the user better understand the content, message or action.


Note the following when including images in your email.

  • Size: To accommodate retina screens, it is best to save your images at least double the intended display height and width.
  • Compression: Keep your files sizes low by using a dedicated file compression program after saving them.
  • Type: Use PNG, JPG and GIF file types as they are the most commonly supported formats.
  • Alt Tag: Include an alt tag because many email clients disable images by default.
