5 Smart Ways to Reduce the Size of Your HTML Email

Be smart with email content

This may sound like a no brainer, but cutting down on your email content is the easiest way to quickly reduce the size of your email design. If you notice your email is getting too long, think about how much content you have included and whether it’s relevant.

Including links to landing pages with more information is a great way to cut down and still keep readers up to date.

Cut down on layout blocks

Layout blocks are a great way to stylishly arrange email content, but too many of them will significantly increase the size of your email design.

One way in which you can smartly use layout blocks is by utilising combi layouts. Combi layout blocks allow you to save space by arranging image and text side by side instead of having to double up and insert separate blocks for each:

Use padding instead of spacers

Another smart hack is to make use of the padding tools. These can be found in the Style menu. Instead of inserting a spacer layout block to create space between blocks, simply adjust the padding to give you your desired amount of spacing. This helps cut down the HTML and reduces the email size.

Optimize newsletter images

This is arguably one of the most important factors when it comes to saving space, as images can add a great deal of weight to your email design.

Luckily, Mail Designer 365 offers an image optimization feature, which automatically recognises the optimal image type for your design. You can also use this tool to compress the size and quality of images.

Keep alt text concise

Every little helps when it comes to saving space. One further way of cutting down the size of your HTML is by keeping any alt text descriptions brief and concise – especially as alt tags which are too long will get cut off in email clients such as Gmail.

Adding an alt tag to an image is easy in Mail Designer 365, simply click on your image and select “Edit Link & Background” in the Style menu:
