There are several ways to test your emails across multiple platforms:
Manual Testing: Send test emails to different email accounts on various email clients and devices. This can be time-consuming but provides a hands-on experience of how your email looks and functions. Email Testing Tools: Use specialized tools like Litmus, Email on Acid, or Mailtrap that offer comprehensive testing across numerous email clients and devices. These tools can save time and provide detailed reports on how your email renders. Browser Extensions: Some browser extensions can help preview how your email will look in different email clients.
