What is Source Code in Email Marketing?
In the context of
email marketing, source code refers to the HTML and CSS code that is used to design and format the content of an email. This code determines how the email will appear in a recipient's inbox, including text, images, and layout. Understanding source code allows marketers to create visually appealing and highly functional emails that can lead to better engagement and conversion rates.
Customization: It allows marketers to customize the email content beyond the limitations of standard email templates.
Responsiveness: Ensuring that emails are
responsive and look good on all devices, including desktops, tablets, and smartphones.
Deliverability: Well-coded emails are less likely to end up in the spam folder.
Brand Consistency: Maintaining
brand consistency through custom fonts, colors, and layouts.
Use Inline CSS: Many email clients strip out
external stylesheets. Therefore, it's best to use inline CSS for styling.
Tables for Layout: Unlike modern webpages, emails still rely heavily on
HTML tables for layout. This ensures better compatibility across different email clients.
Alt Text for Images: Always include
alt text for images. This is useful for recipients who have images turned off by default or use screen readers.
Test Across Clients: Test your emails across multiple
email clients and devices to ensure they render correctly.
Keep it Simple: Avoid overly complex designs and heavy use of JavaScript, as many email clients do not support them.
Common Pitfalls to Avoid
Here are some common pitfalls to avoid when coding emails: Broken Links: Ensure all
hyperlinks are correctly formatted and lead to the appropriate destination.
Large File Sizes: Avoid using large images or heavy attachments that can slow down loading times.
Ignoring Accessibility: Make your emails accessible by using proper
semantic HTML and providing alt text for images.
Non-Mobile Friendly Design: Always use responsive design techniques to ensure your emails look good on mobile devices.
