The Importance of Email File Size
Let us take you through the basics of email file size by sharing some tips on how to reduce the size of your emails and the images inside them.
CSS
Also known as: Cascading Style Sheets
CSS is the styling code that controls how your emails look, including fonts, colors, spacing, and layout.
CSS stands for Cascading Style Sheets. It is the code that tells your email how to look. It controls fonts, colors, spacing, and simple layout. When people talk about making an email look good, they usually mean working with CSS.
Good CSS helps your emails feel on brand and easy to read on any screen. Most email tools take the CSS you write and turn it into inline styles so more inboxes can understand it. You still need to be careful because each email client supports CSS in its own way. That is why the same email can look fine in one inbox and broken in another.
For safer results, stick to simple properties like font, color, padding, and background color. Use tables for layout when you build HTML emails because clients like Outlook handle them better. Always test your campaigns in a few major inboxes before a big send. Small checks up front save you from awkward layout bugs later.
