What is Code Validation in Email Marketing?
Code validation in the context of
email marketing refers to the process of ensuring that the HTML and CSS used to create email templates are correctly written and adhere to industry standards. This is crucial for ensuring that emails are displayed properly across a variety of
email clients and devices, thereby providing a consistent and professional appearance.
Why is Code Validation Important?
Validating your code is essential for multiple reasons. Firstly, different email clients interpret HTML and CSS differently. Code that works perfectly in one client may break in another. Secondly, errors in code can lead to issues such as broken images, misaligned text, and other formatting problems that can negatively impact the
user experience. Lastly, clean and validated code can improve
deliverability rates, reducing the likelihood of your emails being marked as spam.
How to Validate Email Code?
There are several methods to validate your email code. One popular approach is using online tools like the
W3C Markup Validation Service. You can also use email-specific tools like
Litmus or
Email on Acid that provide comprehensive testing environments. These tools can simulate how your email will look in various email clients, helping you identify and fix issues before sending your campaign.
Common Issues Detected During Validation
Some common issues that code validation can help identify include: Missing or improperly nested HTML tags
Unsupported CSS properties
Broken links or images
Non-responsive design elements
Fixing these issues can significantly enhance the overall effectiveness of your email marketing campaign.
Best Practices for Writing Validated Code
To ensure your email code is always validated, follow these best practices: Use
inline CSS instead of external stylesheets, as many email clients do not support the latter.
Stick to
table-based layouts for better cross-client compatibility.
Avoid using JavaScript, as it is generally not supported in emails.
Test your emails across different clients and devices before sending.
