Does My Email Client Allow Scripting?


Heather Bennett

Have you ever wondered if your email client allows scripting? In this article, we will explore the different email clients and their support for scripting, so you can make an informed decision about how to enhance your emails.

What is Scripting in Emails?

Scripting in emails refers to the ability to embed and execute code within an email message. This can be useful for adding interactivity, dynamic content, or tracking capabilities to your emails.

Email Clients That Support Scripting

Let’s take a look at some popular email clients and whether they allow scripting:


Gmail does not support scripting in its default configuration. This is primarily due to security concerns, as allowing scripts could potentially expose users to malicious code or phishing attacks. However, Gmail does support some interactive features through AMP (Accelerated Mobile Pages) technology.


Outlook has limited support for scripting. It allows certain types of scripts like JavaScript and VBScript within emails but restricts their execution for security reasons. Outlook also disables external content by default, so recipients need to explicitly enable it for scripts to work.

Apple Mail

Apple Mail does not natively support scripting. Similar to Gmail, Apple Mail prioritizes security and restricts the execution of scripts within emails.


Thunderbird is an open-source email client that offers more flexibility when it comes to scripting. It supports JavaScript execution within emails but warns users about potential security risks before running any script.

Why Should You Care About Scripting?

If you’re considering using scripting in your emails, here are a few reasons why it might be worth exploring:

  • Interactivity: Scripting allows you to create interactive elements within your emails, such as image carousels, accordions, or forms. This can significantly enhance user engagement.
  • Dynamic Content: With scripting, you can display personalized content based on user preferences or past interactions.

    This level of personalization can greatly improve the effectiveness of your email campaigns.

  • Tracking and Analytics: Scripting enables you to track email opens, link clicks, and other user interactions. This data can help you measure the success of your campaigns and optimize future communications.

Best Practices for Using Scripting in Emails

If you decide to incorporate scripting into your emails, here are a few best practices to keep in mind:

  • Keep it Simple: Avoid complex scripts that could potentially cause compatibility issues or slow down the rendering of your emails.
  • Test Across Email Clients: Different email clients may handle scripts differently. Test your emails across various clients to ensure a consistent experience for all recipients.
  • Beware of Security Risks: Scripts can introduce security vulnerabilities. Be cautious and validate any input received from users to prevent potential attacks.

In Conclusion

In today’s digital landscape, email clients have become more stringent in their support for scripting due to security concerns. While some clients offer limited support for specific types of scripts, others prioritize user safety by disabling scripting altogether. As an email marketer or developer, it’s essential to understand the capabilities and limitations of different email clients when considering the use of scripting in your campaigns.

Note: Always consider the potential impact on deliverability and user experience before implementing scripting in your emails.
