Identification of syntax errors can be achieved through various methods:
1. Email Previews: Use tools like Litmus or Email on Acid to preview emails across different clients and devices. 2. Code Validators: Employ HTML and CSS validators such as the W3C Markup Validation Service to check for errors. 3. Testing: Send test emails to different email accounts and devices to manually check for issues. 4. Quality Assurance: Implement a robust QA process involving multiple team members to review and test emails before sending.
