What is Minification?
Minification is the process of removing all unnecessary characters from source code without changing its functionality. This includes spaces, line breaks, comments, and other non-essential characters. The primary goal of minification is to reduce the file size, which can improve load times and overall performance.Why is Minification Important in Email Marketing?
In
email marketing, reducing the size of your emails can have a significant impact on deliverability and user experience. Smaller email sizes are less likely to be flagged as spam and are easier to load on various devices, including mobile phones. This ensures that your
email campaigns reach your audience effectively and are opened and read.
How Does Minification Improve Deliverability?
Emails with smaller sizes are often preferred by email service providers (ESPs). Large emails can be a red flag for spam filters, which may prevent your emails from reaching the inbox. By using minification techniques, you can reduce the risk of your emails being marked as spam and improve your overall
email deliverability.
Types of Minification Techniques
There are several minification techniques you can use to optimize your email content:HTML Minification
