What is Email Client Testing?
Email client testing involves verifying the appearance and functionality of your email campaigns across different email clients, devices, and browsers. This ensures that the email renders correctly and provides a seamless user experience, no matter where or how it is viewed.
Why is Email Client Testing Important?
Email client testing is crucial because different email clients interpret HTML and CSS in unique ways. An email that looks perfect in
Gmail might appear broken in
Outlook. Testing helps you avoid such issues and ensures that your
email marketing efforts are not wasted due to poor rendering.
