There are several types of email tests you can perform:
A/B Testing: This involves sending two variations of the same email to a small segment of your list to see which version performs better. Spam Testing: This checks if your email is likely to be flagged as spam by various ISPs. Rendering Tests: These tests ensure your email looks good on different email clients and devices. Link Testing: This ensures all the links in your email are working correctly. Content Testing: This involves checking the email copy, images, and overall design for errors or inconsistencies.
