The tool also allows you to preview your templates in both desktop and mobile views, ensuring your emails are responsive and look great on any device.

Frequently Asked Questions

How accurate is the email client simulation?

Our tool simulates the rendering behavior of different email clients based on their known CSS support and rendering engines. While it's not 100% identical to the actual clients, it provides a very close approximation that helps identify most rendering issues before sending your emails.

Which email clients are supported?

Currently, we support Gmail, Outlook, Yahoo Mail, Apple Mail, and Thunderbird. These represent the majority of email clients used by subscribers today. We're continuously working to add more email clients to our simulation.

Can I test responsive email designs?

Yes, our tool includes both desktop and mobile view options. When you select mobile view, your email template is displayed in a simulated mobile device frame, helping you see how your responsive design adapts to smaller screens.

Does the tool support CSS inlining?

Our tool simulates how each email client handles CSS. Some clients like Gmail require CSS to be inlined, while others support embedded stylesheets. The simulation reflects these differences, helping you understand how your styles will be interpreted.

Can I save my tested email templates?

Currently, the tool doesn't have a built-in save feature. However, you can copy your HTML code from the input area and save it locally for future use. We' re planning to add template saving functionality in future updates.
