When testing your HTML emails, pay attention to several key aspects:
Rendering Issues: Check for broken layouts, missing images, and incorrect fonts. Ensure that your email looks consistent across different platforms. Links and Buttons: Verify that all hyperlinks, buttons, and call-to-action elements are working correctly and lead to the intended destinations. Load Time: Ensure that your email loads quickly. Large images or heavy code can slow down load times, which can frustrate recipients. Responsive Design: Test your email on various screen sizes to ensure that it is mobile-friendly and looks good on both desktop and mobile devices. Spam Filter Checks: Use tools to check if your email is likely to be marked as spam. This helps ensure that your email reaches the inbox of your subscribers.
