What is Code Hygiene in Email Marketing?
Code hygiene refers to the practice of keeping your HTML and CSS clean, organized, and functional when creating email templates. This includes following best practices for coding, ensuring compatibility across different email clients, and regularly updating your codebase to maintain performance and security.Why is Code Hygiene Important?
Neglecting code hygiene can have significant repercussions for your email marketing campaigns. Poorly maintained code can lead to rendering issues, making your emails look unprofessional or even unreadable. This can harm your brand's reputation and reduce
engagement rates.
How Does Neglecting Code Hygiene Affect Deliverability?
ISPs and spam filters often scrutinize the coding structure of emails. If your code is cluttered or contains errors, your emails are more likely to be flagged as spam. This directly affects
deliverability, reducing the number of emails that reach your subscribers' inboxes.
What Are the Risks of Poor Code Hygiene?
1.
Rendering Issues: Different email clients interpret HTML and CSS differently. If your code is not clean and standardized, your email may not render correctly across all clients.
2.
Increased Load Times: Poorly written code can slow down the loading time of your emails, frustrating recipients and leading to lower
click-through rates.
3.
Security Vulnerabilities: Neglected code can become a security risk, making it easier for malicious actors to exploit vulnerabilities.
4.
Maintainability: Untidy code is difficult to update or modify. This can make it challenging to make quick changes or troubleshoot issues, leading to inefficiencies.
How to Maintain Code Hygiene?
1.
Use Inline CSS: Many email clients do not support external style sheets. Using inline CSS ensures that your styles are applied consistently across all platforms.
2.
Avoid Unnecessary Code: Remove any redundant or unused code. This helps keep your email lightweight and easier to manage.
3.
Validate Your Code: Use tools to validate your HTML and CSS to catch any errors or warnings.
4.
Comment Your Code: Adding comments can help you or anyone else understand the structure and purpose of your code, making it easier to maintain.
5.
Test Across Clients: Ensure your emails render correctly by testing them across different
email clients and devices.

2. Email on Acid: Another popular tool for testing and debugging your email code.
3. W3C Validator: A free tool to validate your HTML and CSS code.

Consider a scenario where an email appears perfectly on desktop but breaks on mobile devices. This often happens due to neglected code hygiene, where media queries or responsive design principles were not properly applied. In another case, an email might get flagged as spam because it contains broken or suspicious code snippets, reducing its
open rates.
